Sun Baked Observatory Shroud


Sun Baked Observatory Shroud for Successful Solar Imaging
Imaging the sun with a mobile phone camera function is possible, however the touchscreen can be very problematic. For example, iPhone has a highly reflective screen that reflects so many images in bright sunlight, the photo image on the screen becomes completely lost in the reflective glare.

One simple solution is to make a hood of black material, with plenty of air circulation ventilation. An anti-reflective screen cover may also help. As a third option, go to settings and change the phone screen brightness to maximum.

Acuter Maksy 60 & Celestron Nexyz


Acuter Maksy 60 & Celestron Nexyz

At first glance, and for the impatient, it would seem the Celestron Nexyz mobile phone mount was not going to work for the Acuter Maksy 60 telescope.

Above Photos: the best arrangement was found by rotating the 90-degree diagonal and tilting the mobile phone in its mount slightly to one side.

The ten ounces added significant weight to the light 1-lb Acuter Maksy 60 OTA and would appear to burden the tiny tripod. To make matters worse, the rack mechanism appeared to ram into the OTA when the phone was positioned back over and above the OTA to gain some semblance of balance. 

The Acuter has a permanent balance point over the tiny tripod and is not adjustable. In some positions, the weight of the mount and phone can tip over the telescope and tiny tripod.

Left & Above Left: Arrow marks the rack support that rams into the telescope's OTA preventing the attachment of the mobile phone holder. This happens when positioning the length of the mobile phone above and along the OTA when trying to achieve the best balance. 

However, all these points are fixable by positioning the mount and phone camera as seen in the photo at the top of this page.

Left: make sure the control knob does not ram into the Acuter Maksy 60 OTA optical tube assembly.

A small amount of experimenting and various adjustments by trial and error will bring the mobile phone and its mount to the correct position, with no tube interference and no telescope tippage. Top photos show one correct way to position the cell phone and mobile phone holder, for no tube interference and the best weight balancing. At left, the knob is ramming into the tube.

The Celestron NexYZ is well constructed, easy to use, and the cell phone clamp has a perfect amount of grip - not too heavy and not too loose. The grip does not press on the buttons at the side of the iPhone. The Celestron NexYZ has become the mobile phone holder for astro imaging, by choice. The holder currently sells for about $80.95. Note: the best balance position may vary depending on the telescope's orientation for the object which is being viewed.

“Unlike other adapters, the NexYZ features three directional knobs (X, Y and Z axes) that perfectly align your phone’s camera with the scope eyepiece in seconds. In addition, you can make tension adjustments to keep the phone firmly in place and, rather pleasingly, the clamp system allows the phone to be positioned to capture images in landscape mode as opposed to portrait, which is so often the hallmark of most smartphone images.” – from Expert Reviews, Birdwatch magazine, November 2018

“Fitting the phone to the adapter is simple and quick, and the phone is held securely in place – no need to worry about it dropping out as you move around. You then adjust the phone’s position using the X and Y axis knobs – this too is easy and relatively quick. Finally, the Z axis knob enables you to lower or raise the phone to eliminate vignetting.” – Matt Merritt, “Unlock your phone’s potential,” Gear Reviews, Birdwatching magazine, August 2018

On the Road to Better Mobile Phone Imaging

On the Road to Better Mobile Phone Imaging

Every time one is forced to touch the mobile phone's touch screen, as in taking a photo, vibrations are introduced into the telescope system along with being open to touch pad errors.

In the case of videos over photos, two jarring taps are needed instead of one. The first to start the video and the second to stop the video.

Photos will blur due to motion. Fingers may be too dry and not register the tapping, tapping may need to be repeated, and tapping for exposure is a problem. Moisture in the air may create touch screen failures and anomalies.

The idea is to use a wireless bluetooth operated mobile phone camera remote control for the shutter. This will not introduce vibrations and taking a photo does not require tapping on the touchscreen. The device is so small, it can be worn on a necklace strap or bracelet so as not to become lost and also to remain handy for quick use.

If you have an older phone and a newer phone, two different remote shutters may be needed, one for each phone based on the differences in bluetooth frequencies or the changing technology standards and the phone's programming differences. These devices are not expensive and generally cost between five and ten dollars.

The remote shutter uses one button battery, CR2032, and it's a good idea to keep a few spares on hand. The range of the Bluetooth® connection is approximately 30 feet (10 meters). However, maximum communication range will vary depending on obstacles (person, metal, wall, etc.) or the electromagnetic environment.

Celestron Mobile Phone Mount


Celestron Mobile Phone Mount

According to photos, the good design of the Celestron Nexyz camera holder does not interfere with the iPhone side buttons which are located mainly towards the top half of the cell phone. Therefore the phone mount will not cause trouble by depressing the side buttons when using the phone for astro imaging. The only concern for small telescopes may be the additional 10 oz. weight.

My Observatory Summary

Bad Phone Camera Mounts


Bad Phone Camera Mounts

Beware of numerous cheap phone camera mounts that fail because they grip the side of the camera exactly where the side function buttons are located.

The key is knowing the position of the phone's side buttons and the finite distance to the eyepiece center relative to where the mount grips the phone.

Another shortcoming is the grip tension is far too much and not adjustable. One way or another, this firmly depresses the side button(s) and the camera fails to operate correctly. Maybe these work with mobile phones other than Apple brand - the key is knowing the position of the phone's side buttons and the finite distance to the eyepiece center relative to where the mount grips the phone.

Units tested are seen in the photos - one that tightens around the top of the eyepiece by turning it and other that uses a screw to tighten the tension around the eyepiece (bottom photo). Both mounts pinch the side buttons on the Apple cell phones with too much force, thus activating the buttons and their respective functions.

The next mobile phone mount to be examined and tested is the Celestron Nexyz. This has adjustments along all three geometrical axes and according to the photos, the gripper is at the lower section of the phone, away from the live buttons.

Acuter Maksy 60 Phone Mount

Acuter Maksy 60 Phone Mount

Don't waste a lot of time trying to find the correct band combination to hold your phone exactly over the eyepiece opening. If the band tension is not just right, or with too many bands, too tight or too loose, the phone camera will not stay over the opening above the eyepiece and won't have the ability to undergo fine positioning adjustments.


The photos show how to position one band (front and back connections) and allow the side positioned camera to reach the opening and maintain its position. One band was removed because two bands put too much tension on the phone and trying to position it resulted in the wrong position.

Left: the backside of the Acuter stock phone mount should look like this for positioning the camera with the proper tension. The use of only one band is needed.

The reason for this unusual design is there are no phone side grippers. I tried several different phone mounts with side grippers and they all interfered with the side buttons on the phone and could not be used.

This applies to the Apple iPhone 6 Plus and Xs Max.

The designers at Acuter Optics knew what they were doing when they designed this mobile phone holder. It does not pinch the sides of the phone and does not interfere with the side buttons or the operation of the iPhone. Read about bad phone mounts:

Trials & Tribulations Acuter Maksy 60 at Sun Baked Observatory



Above: Attempting high magnification at the Sun's limb produced this unusual appearance - the system needs additional tuning to clearly show sunspots and solar flares and edge prominences.

Exposed with the primary solar filter but no fine tuning engagement of H-Alpha filtering.

Left: at 20mm EP projection and hand holding the iPhone camera, the solar disk was overexposed and getting the iPhone to compensate was insufficient. However, overexposure has advantages and some prominence-appearing minute detail is beginning to appear at the solaredge as well as the graduations towards the photosphere.

Trials & Tribulations of the Acuter Maksy 60 at Sun Baked Observatory
The Acuter Maksy 60 is being tuned for solar work. A number of fixes are needed before this telescope will be fully up and running.

Here's a List of Numerous Anomalies Encountered on Sunday May 29 2022.

Small Stock Tripod Insufficient to Hold Weight
The small tripod mount is insufficient to hold the telescope and the weight of the iPhone.

Small Stock Tripod Cannot Reach Elevation
The small stock tripod must be rotated to a small gap opening at the top to get it to reach a higher elevation, otherwise it bumps into the mount which is very limited. It's inconvenient to stop and move the entire mount and telescope for a position that works better.

Small Stock Tripod Insufficient to Make Fine Motions
The small tripod mount is incapable of making the fine motions needed for adjustments to image positioning

Small Tripod does not fit the Observatory Platform
The small tripod did not fully fit the observatory platform

Stock Phone Mount Failure
The stock iPhone mount failed - mount number one with the stock bands was not fully adjustable and the phone camera would not stay over the eyepiece at the proper position

Phone Mount 2 Failed
The 2nd iPhone mount failed - it pressed on the side of the iPhone against the function buttons and locked p the phone

Phone Mount 3 Failed
The 3rd iPhone mount failed, the lock holding the phone was not able to have fine tuning.

Phone Mount 4 Failed
The 4th phone mount failed, it was too heavy.

Sun Blocked by Roof
Just as the project was getting started, the sun moved into a position blocked by the roof.

Clouds & Haze Obliterates Features
The sun features were relatively void due to viewing the sun through the clouds and haze.

iPhone Touchscreen Failure
The iPhone continued to fail as any touch to the screen activated some unwanted feature.

iPhone Screen Not Visible
The iPhone screen was invisible in the bright sun - a shield was fabricated but it too had too many reflections to see anything.

Two iPhones both Fail
Two different iPhones both had the same problems.

iPhone Goes into Undesired Modes
Just setting on the table, the iPhone goes into undesired modes not conducive to astro imaging. Anything near the screen or touching it randomly is a problem.

Observatory Platform Needs Moving
The observatory platform needs to be completed in construction and moved to an ideal location.

Battery of Telescopes

Battery of Telescopes

In this experiment, a battery of telescopes will attach to the Celestron Nexstar 6SE and mount.

The primary concern is not to overrun the mount's payload capacity which is quoted as 12 pounds.

https://www.celestron.com/blogs/knowledgebase/what-are-the-payload-capacities

The larger telescopes attached to the 6-inch f/10 Celestron OTA will be the Acuter 60mm Maksutov-Cassegrain OTA weighing in at one pound at 8-inches long, and the Orion Optics 80mm f/5 CT-80 refractor achromat doublet OTA at 2.25 lbs and 14.75-inches long. Attaching the telescopes to the Nexstar 6SE will use the Celestron camera mount and another mount
incorporating a Dovetail shoe.
The weight total is 3.25lbs and this leaves some extra load capacity for a finderscope and the add on weight of the extra mountings and accessories like eyepieces and a 90-degree star diagonal. Extra telescopes can take advantage of this extra sturdy mounting and utilize the tracking drive and possibly the goto features and database.

Weather

The weather is day and night non stop rain and in a new cycle of Monsoons. However, for exactly 5-seconds today, the sun popped through a sucker hole in a patch of overcast that formed a broken cloud. There was not enough time to use the telescopes on the Sun and then it went back to raining. It's my fault as I bought two new telescopes and this is the double whammy of the curse - new telescopes equal clouds and rain.

No Occultation of Moon Venus
On Friday, it rained and the rare Venus being occulted by the Moon was not visible. Above is a computer planetarium simulation.

Observatory Platform
The required number of 40 recycled bottles is now saved up for completion of the telescope outdoor observatory platform but the deck is soaked from rain and the fitting will need to wait for dry conditions. An extra 3 bottles are available and this number may grow.

New Astro Imaging Section
The Astro Imaging web site has introduced a new section, "What's Behind the Clouds." A computer planetarium program will be used to see and study the simulation of celestial events that otherwise could not be seen.

Mount Calibrating Solar System Objects


Quick-Align uses all the date and time information entered at startup to align the telescope, However, instead of slewing to the alignment stars for centering and alignment, the telescope bypasses this step and simply models the sky based on the information given. This will allow you to roughly slew to the coordinates of bright objects like the Moon and planets and provides the telescope with information needed to track objects in any part of the sky (depending on accuracy of polar alignment). Quick-Align is not meant to be used to accurately locate small or faint deep-sky objects or to track objects accurately for astroimaging.

To use Quick-Align, simply select Quick Align from the alignment options and press ENTER. The telescope will automatically use the entered date/time parameters to align itself with the sky and display Alignment Successful.

SOLAR SYSTEM ALIGN WITH NESTAR 6SE
Solar System Align is designed to provide excellent tracking and GoTo performance by using solar system objects (the Sun, Moon and planets) to align the telescope with the sky. Solar System Align is a great way to align your telescope for daytime viewing and a quick way to align the telescope for basic nighttime observing.

To perform a Solar System Align
1 - Once the telescope is powered on, use the SCROLL UP and SCROLL DOWN buttons to select Solar System. Align Press ENTER

The hand control will display the last time and location information that was entered into the hand control. Press ENTER to accept the current information or press BACK to manually edit the information (see SkyAlign section on page 10 for detailed instruction on entering time/site information).

2 - The SELECT OBJECT message will appear in the top row of the display. Use the SCROLL UP and SCROLL DOWN buttons to choose a Solar System object (a planet, the Moon, etc ) to use for alignment. Press ENTER

3 - The hand control will then prompt you to use the direction arrow buttons to slew the telescope to the alignment object and carefully center it in the finderscope. Press ENTER when centered.

4 - Then, center the object in the eyepiece. Press ALIGN

Once in position, the NexStar SE will model the sky based on this information and display “Align Successful”

Sun Baked Observatory Report


Sun Baked Observatory Report
The Sun is ramping up activity according to NASA's announcement of X-class solar flares, and observers who have seen large sunspot groups with the unaided eye. Online services have issued multiple aurora alerts even for mid-latitudes.


According to Sky & Telescope, after years of quiescence — the Sun was more often spotless than not in 2018, 2019, and 2020 — the change of pace is exciting solar observers. The Sun goes through 11-year cycles of magnetically instigated activity, which include sunspots, flares, and massive eruptions. While such activity last peaked around 2012 through 2014, that maximum was meager at best. In fact, it marked one of the quietest cycles in 100 years. Now, the uptick in activity seems to mark a change in the Sun’s behavior.

The consensus model from Solar Cycle 25 Prediction Panel (red line) slightly underpredicts the Sun's current activity (sunspot numbers shown in black). But there's wiggle room in that prediction: give or take six months for the cycle's start and give or take 10 sunspots for the daily sunspot number. With an slightly earlier start and higher activity, the panel's forecast is still spot on. Space Weather Prediction Center

Spectroscopic Clouds





Spectroscopic Clouds

Is there any hope of penetrating these clouds by altering the spectroscopic ranges of vision?


This is the experiment to look through water vapor or clouds using spectral variances in optical light moving towards the infrared spectrum. I used the first batch of four experimental filters held in front of the iPhone camera lens and got these results. From top to bottom, a light red filter (AngelEyes W23A), H-Alpha (ZWO Ha 7nm), ProPlanet (Astronomik 742 IR), and deep sky (Optolong UHC). 

According to these results, which need to be confirmed, the red filter is the worst and actually enhances the clouds. The narrowband H-Alpha filter is the best at penetrating the clouds. The ProPlanet is second best and produces some interesting results by reversing the colors of some areas which will need additional analysis, and the deep sky filter also enhances clouds making second to the red filter. In the next series of trials, the focus will be on polarization. The study was stopped at this time because the sky quickly turned to overcast and rain.

Looking Inside an Atmospheric Hole


Looking Inside an Atmospheric Hole
To penetrate the atmospheric sky hole and look inside to see the portion invisible to human eyes, I ran an image processing program to examine optical properties in greater depth and detail.

As can be seen, the small area is not clear or an actual hole, because it contains a large amount of obscuration. This would interfere with telescope observations and create distortions in the final image. The next step is to optically polarize the region, then introduce a series of physical and optical spectroscopic filtering for water vapor.

Sticky Clouds

Sticky Clouds

These clouds can't make up their minds to become sky clouds or land clouds. At the present time, they seem to have chosen both states.

Today is Thursday, May 26th, 2022 - just one day before the Occultation of Venus  by the Moon. I hoped we might have sky clearing but no chance of that according to the weather man. Tomorrow looks like 90% chance of rain. Maybe we'll have some good luck with sucker holes in the clouds if the rain stops momentarily. Currently it's raining but we had the sun shine through a sucker hole for about 2 minutes. I've noticed a large amount of haze obscuring and dimming the views through these holes.

Weather
The weatherman has updated the weather forecast to rain every day for the next two weeks. This is undoubtedly the curse of new telescope = rain. And to think, I bought two new telescopes and all the accessories! I don't know when I will ever see clear skies again! Even the distant mountains are going invisible.

The Curse of New Telescope = Clouds
https://otisastro.blogspot.com/2022/05/the-curse-of-new-telescope-clouds.html



Left: The mountains are almost totally invisible. No solar imaging today and no imaging of the mountains or wildlife studies. Rain continued all day and into the evening. The weatherman claims the rainy season Monsoon has reared its ugly head.

Left: after 20 minutes, the mountains were gone due to the proverbial mix of rain, mist, fog, smoke, air pollution, smog, and 100% humidity.









Observatory Construction
Work on the outdoor observatory has stopped due to inclimate weather and rain. A total of 40 recycled water bottles, each at 1,000 psi strength, blanketing 40,000 psi for earthquake resilience, are now collected and waiting for clear weather and the fitting process to the telescope platform and to the elevation safety guard railing which is anchored in steel, cement, and granite on the side of the skyscraper. The telescope platform must conform to a small granite floor a mere 15-inches in depth. It will be advantageous to automate most of the telescope functions, limit load weight, and minimize exposure to the outdoor elements. This can include bites from deadly bugs in this subtropical/tropical zone.

Sun Baked Observatory Study
Studies begin with successful data obtained from previous/past historical imaging sessions. I'm working with several software packages and testing the results on the sun. Developing new techniques and inventions will be a high priority. Several posts detail the telescopes used for solar studies that began in 1965 through the present day. https://otisastro.blogspot.com/2022/05/sun-baked-observatory-explores-venus.html

Orders
All remaining orders are on temporary hold due to mitigating and extenuating circumstances.

Indoor Work
Indoor work, such as organizational, is proceeding with indoor observatory areas.

Telescope Lifting
After heart surgery and the long recovery process, in order to ever lift the most heavy telescopes and their mountings again in the future, I have taken up weightlifting. Today I worked arms and legs on a split routine with multiple sets of repetitions. It's hoped the sum total of all this work will lead to greater longevity, increased health and well being, and a possible life span to 2066 - the quoted life of some of the heart related machine components.  https://humanoidolabs.blogspot.com/


Lofted Fog Phenomenon
Under an Overcast Sky: Just when we thought one small patch of Lofted Fog was interesting, a short time later 20 appeared. These are big and spread across the ten mile span. Locals claim that weather patterns have changed from the traditional seasons and predicting when the current Monsoon rainy period will end is anyone's guess.

Sun Baked Observatory Explores Venus Atmosphere During Solar Transit

 
Sun Baked Observatory Explores Venus Atmosphere During Solar Transit

We are constantly developing new ways to process and extract data from raw solar imaging. Much of these efforts are experimental and subjective. This time we've enhanced the atmosphere thickness surrounding Venus during a solar transit when Venus was passing in front of the Sun, and looked for Venusian atmospheric detail across the planet.

Topmost Image: This is the final step 4 in the processing cycle. Here we see Venus moving across the face of the sun, approaching the solar limb. The Sun and Venus final result show the appearance of detail in the atmosphere of the planet and a surrounding atmosphere of varying thickness outwards from Venus. The color shows the differentials.

Immediately Above: Step 2 in image processing will determine if any data is present in the raw image as related to the planet and the surrounding region of atmosphere, and if it warrants continued processing.

Left: This is step 3 in the process after
step 2 determines the presence of imagery on Venus and adjacent features, suggesting a surrounding band of thick atmosphere that sunlight is filtering through. The changing solar plane also shows detail closer to the Sun's limb as it receives color encoding to specify the intensity levels of objects discerned. This is also a first level step in reducing the luminosity differential between the Sun and Venus.

At left: Step one in the solar-venus process is to acquire a raw image of Venus traveling across the face of the extremely bright sun. At these great and vast luminosity differences, Venus looks like a black featureless disk, i.e. until processing can view the underlying sheath of light differentials. This image is first processed to reduce the effects of Venus' motion and increase the clarity and sharpness of underlying features.

Saturn Blazes Beyond Belief





Saturn Blazes Beyond Belief
Saturn, the ringed planet is still approaching opposition, yet offers a plethora of spectacular features for study and observation. Get your largest telescope ready for this ringed marvel to collect as many photos as possible during astro imaging as it begins to put on a show blazing beyond belief!

This view of the ringed planet Saturn shows there's much more to view other than the main ring. The planet is rich with points awaiting study - the many ring systems, the view of the globe through transparent rings, varied colors, planetary spots, the axial tilt of the rings, the atmospheric variations on the planet and a changing climate, Saturnian storms, the changing polar cap, a study of color variations in belts and bands, stars that occult through the rings, the projection of the globe's shadow onto the rings, and the many moon systems. For best results, a Celestron EdgeHD C14 CGX/L and ideal local conditions are suggested.

History of Solar Telescopes at Otis Astro Imaging

The history of solar telescopes began in 1965 and has continued ever since. Otis Astro Imaging now has these telescopes inside solar observatories doing their work and studies. 

Above: The first solar telescope is a 4.25-inch f/11 reflector from Edmund Co. which is fitted with a purchased accessory glass solar filter, possibly purchased from the former Kenneth Novak and Company. Numerous photos are taken of sunspots and a solar eclipse.

Left: the 2nd solar telescope is a low cost bare bones Celestron 2.99-inch FirstScope f/3.95 Newtonian reflector on a tiny Dob mount - The telescope is fast to setup and lightweight to carry around and transport. It has a focal length of 300mm (12-inches). It was purchased at a toy store in Beijing, China. For solar use, the telescope needs an accessory solar filter film mounted over the front of the telescope tube for best results (sold separately). The grab n go portability and no setup time makes this telescope a first choice for ease of use. General land & Moon images are taken by holding the mobile phone over the eyepiece for eyepiece projection and selecting the best result.

Left: The third sun telescope is the Meade f/5.6 ETX-60AT Refractor is used for solar transits and for studying sunspots. One special study captured the disk of Venus in front of the sun during the June transit and is examining the atmosphere fringes out from the planetary disk and any Venusian surface features.

The 60mm telescope is a precision achromatic refractor on a battery powered GOTO mount. The telescope has very high resolution and is a very good performer. The telescope has a flip mirror, with positions for the eyepiece or straight-through for astro imaging.


Left: 4.5-inch f/4 Orion Starblast is German equatorially mounted and outfitted with an extra accessory electronic sidereal drive and a Chinese solar filter made with Baader solar film. The filter is shared with a second Orion Starblast on a Dob mount.

The second telescope is a Celestron 2.99-inch reflector on a Dobsonian mount that uses solar projection in conjunction with a high concentration of air pollution, in Beijing China. Images were published at the Parallax Forum by Humanoido.


Left: The fifth telescope is the Orion StarBlast 4.5-inch f/4 RFT reflector with a grab and go Dob mount. This telescope shares an identical solar filter with the first equatorial mounted Orion Starblast telescope.

The telescopes have different purposes - one is more ideal for the static observatory and the other is perfect for a portable observatory with the grab and go telescope.

The third telescope is a Meade ETX60AT (2.6-inch) f/5.8 achromatic refractor used to observe the transit of Venus from a skyscraper rooftop.

A solar sunspot study was made in full color on the previous day of June 5th, 2012 at 4:43:48 pm local time, using ISO125 at 1/400 F5.6 to identify the position of solar spots, test the imaging results, obtain satisfactory full disk image size and resolution, position enlarged disc views, and lock down the setup and imaging procedures. (see June 5th
photo).

The fourth and fifth telescopes are Orion StarBlast 4.5-inch f/4 with a driven equatorial mount and a grab and go Dob mount. These share a solar filter obtained from China.

Telescope six is a Celestron Nexstar 6SE f/10 on a goto mount that fits the Celestron solar filter.

The newest addition is telescope seven, the famous Acuter Maksutov-Cassegrain Catadioptric 60mm (2.4-inch) f/12.5 with its own solar filter. The solar filter is an extra purchase.

Seen at left, the filter form fits tight onto the front of the Acuter 60mm Maksutov-Cassegrain telescope's OTA. The filter assembly contains a safe projection sun finder molded into the carrier and offset to the side of the filter.

This system is very convenient to carry around (the OTA weighs only one pound) and it has a setup time of only a few minutes. It can compete with finding and utilizing the holes in the clouds to quickly capture views of the sun and sunspots within their 20-minute openings. The setup is ideal for transits and solar eclipses. Others have used the telescope for attaching H-Alpha filters for viewing of the chromosphere, solar prominences etc.
