Celestron Nexstar 6 SE Looking Through Window Glass

THE INDOOR OBSERVATORY

Celestron Nexstar 6 SE Looking Through Window Glass

This ongoing page is dedicated to indoor observing by looking through window glass with the Celestron Nexstar 6 SE telescope.

Years ago when astro imaging with small telescopes, like the 2.99-inch Celestron Firstscope, it was discovered that it was possible to photo solar system objects through a closed window while the telescope remained indoors. The window was kept closed to avoid the excessive summer heat, high dew forming humidity, and deadly bugs and killer mosquitoes carry Dengue Fever. This indoor observatory also experimented with a Celestron EdgeHD 14 and 9.25-inch telescopes. Now moved to a new location with more space, more windows, and newer windows, indoor telescopes will prevail.

There are several tricks to observing through window glass to get the best results, some of which are controllable and some are not. Here's the top of the ongoing bucket list:

* Have access to new white float glass with higher precision flats

* Do not use tinted glass

* Clean the both sides of the glass just before observing

* Do not use double or triple insulated windows

* Keep the window closed

* Inspect & remove any dew, frost or dust from the glass when observing

* Do achieve indoor thermal equilibrium with indoors/outdoors

* Move the telescope as perpendicular as possible to the glass

* Measure window aperture, plot when objects will become visible using

   planetarium software

* Measure & know clear sky altitude, azimuth and horizon

* Have exact latitude longitude for telescope GOTO

* Computer image "process out" window glass

* Subtract any secondary reflections from the back of the glass

* Make any color corrections necessary

* Boost compensation contrast & sharpness as necessary

* Smaller telescope apertures may minimize aberration differentials

* Move the telescope closer to the glass to increase sky viewing area

* Use lower EFRs to minimize magnifying any defects

* Avoid glass bubbles, striations or any defects

* Avoid telescope tube obstruction by window frame

* Correct for achromatic and chromatic aberrations from the window glass

How to Subtract Achromatic Chromatic Aberrations

Depending on factors (window glass type, angle of telescope relative to the plane of the window), correct for typical achromatic chromatic aberration from the window glass when the image has blue on one side and red on the opposite side by employing a ZWO ADC Atmospheric Dispersion Corrector to correct the image at the telescope. Aberration effects can also be minimized through final image processing on the computer.

Monster Astro Projects

New Orion brand telescopes wait as skies begin clearing

Monster Astro Projects & Updates
The largest projects are described as of Wednesday, November 10, 2021

Numerous ongoing projects make use of the telescopes for astro imaging, conservation, weather, and technical studies. Never a moment lost - if the day is clear, the telescopes are pointed to the mountains to study and statistically categorize the ecology to include plants and animals, large insects and terrain. This area is surrounded by mountains, some 100 miles away, and the telescopes provide exceptionally clear magnified views for visual studies and photographic imaging.

If the night is mostly clear but with sections that may have upper atmosphere haze, or smog, fog, air pollution, heavy humidity, or breaks in the clouds, various inventions are deployed to penetrate the hood to resume astronomical observations.

Main divisions include:

* Singularity Observatory

* Solar Observatory

* Astro Imaging Laboratory

      Equipment, telescopes, accessories purchases

* Conservation

      Forestry study of mountains, plants, animals, birds and resources for

      conservation

* Cartography

      Moon mapping & atlas creation for lunar colonists

* Atmospheric Studies

      Invented methods to penetrate clouds, haze, air pollution, water vapor and haze

Main Sections

* Outdoor Pacific Ocean Astronomy

* Indoor Astronomy

* Armchair Astronomy

Perfect Weather & Clear Skies

The month of November is going exceptionally well. The weather has cooled to the perfect temperature of around 70 degrees and the skies are mostly clear and transparent, providing outstanding views of the mountains for conservation studies and the sky for planetary observations and weather studies. Mother nature has given five months of clear nights after two years of rain and overcast conditions.

Accessories, Inventions

This year has see the purchase of accessories and inventions to penetrate clouds, haze, air pollution, water vapor and haze. 

Telescope Trends

The trend of telescopes: at age 20, the goal was to make the largest telescopes possible. The progression went from 4.25" to 8 and then 12.5. At age 30s, weightlifting helped with strength to build and hoist the world's largest amateur telescope with a plate glass objective at the time - 40 inches in diameter. This was followed by two 50-inch telescopes around age 40s. At age 50s, the telescopes progressed into new inventions - giant power telescopes and then super large space telescopes using recycled nasa parts in space worth trillions of dollars. By age 60s, methods were invented to amplify the power of smaller telescopes into 925 and 1,400 inches aperture. By age 70, the telescope continued to shrink so they could become more manageable, easier to carry and set up.

Digital eVscope Not for this Region

It was finally discovered that, among other problems, Unistellar eVscopes in this region fail due to the combination of severe light pollution combined with haze that occludes and obstructs swaths of stars preventing the telescope from properly calibrating and plate solving.

Busy Making the Lunar Atlas

With renewed interest in the Moon, new private industry moon landings, scientific lunar outposts in the making, upcoming vacation tours to the Moon and potential off-planet colonization, a lunar atlas is in the works. It uses actual raw and processed lunar imaging from our best and most powerful telescopes at Singularity Observatory.

Observing the Sun

Recent telescope upgrades now include a solar observatory, complete with solar filters, abilities to view and image and count solar sunspots to determine sub periods of min and max, transits, eclipses, specula, and other phenomena. Tests will be made on prominences and the solar corona, and correlations with the aurora borealis and aurora australis.
