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.

Venus Jupiter Conjunction

 
INDOOR ASTRONOMY
Venus Jupiter Planetary Conjunction

The planets moved closer when the sky was raining and overcast for two weeks. During some partial clearing on the morning of Thursday, May 12, 2022, both Venus and Jupiter made an appearance. Jupiter, at right, was up around 30 degrees in altitude at 4:48 when this photo was taken from indoors with a mobile phone - Apple iPhone XS Max 4.25mm f/1.8 ISO500 1/30 second exposure. The photo was processed with multiple software and Apple iMax Catalina to remove window glass.

All Four Planets
Depiction: Facing southeast, all four planets in the current conjunction - this depiction shows the view to the right of the photo above, seen are two more planets - Mars and Saturn. These are currently around a half year or more from opposition and very dim, and were seen popping in and out of view through the moving clouds and haze. Light pollution and upper atmospheric haze is seasonal and is very heavy in this region of urban astronomy and can obliterate objects as bright as zero magnitude. From lower left to upper right - Venus, Jupiter, Mars, Saturn. The diameter of the objects simulates the approximate brightness in magnitude.  Approximate color is also added.

Acuter Mak 60 Planet Observations

Jupiter and Galilean Moons near Jupiter as observed by Mike Otis early morning May 12, 2022 with the new Acuter Maksy 60 telescope using a 20mm EP and table top mount. The drawing graphic depicts two of the three moons visible and the image scale is vastly increased from the raw visual. The moon closest to Jupiter is Io and farther to the left is Ganymede. Not shown at this image scale, located farther to the left is Europa.

Acuter Mak 60 Planet Observations
On the early morning of May 12, 2022, around 4 to 4:20 am, the Acuter Maksutov-Cassegrain telescope was used for the first time to observe all the main planets Venus, Jupiter, Mars and Saturn. A number of things were learned about the telescope.


Left: the smaller image scale is more like the visual at the telescope and depicts Io, Ganymede and Europa from right to left. The observations were made through window glass at around 4:20 am on the morning of May 12th. At a 30-degree altitude, Jupiter had the least effect from the atmosphere compared to Venus.

* The 20mm eyepiece with 37.5x is too low a magnification to show significant detail on planets. It is, however, good for showing all the Galilean moons of Jupiter. For detail on the globe, the telescope should be ramped up to around 120x but then tracking the planet will become a great challenge.

Venus was spectacular in brightness and showed a "moon-like" phase. The low altitude was affecting the image. This drawing rendition by Mike Otis shows the phase of Venus through the new Acuter Maksy 60 telescope and a 20mm eyepiece. The scale is greatly exaggerated.

Left: this depiction of Venus and its phase, with the 60mm telescope, is closer to the actual visual observation regarding image size. At the lower "bubbling atmospheric" altitude and with the brightness of Venus, the phase was a challenge

* The small table top tripod is insufficient for astro imaging of planets and fine detailed motions. Therefore, the first observations included here will be various visual drawings and representations. In the future, the Maksutov will mount onto the Celestron Nexstar 6SE and have total digital control and tracking.

Left: Mars was a tiny dot very pronounced in orange color and too small to see any detail

* The bumps on the side of the telescope are not sufficient for finding objects during the night. Even with some illumination near the telescope, the bumps are difficult to see and line up. For study other than the Moon, a finderscope is needed. The Mak could also be mounted on another telescope and use its finding resources.

Saturn and its ring systems were too small to show any detail and the image scale from a 37.5x ocular was not enough. When Saturn is closer to the Earth, 120x should show more. The visual depiction here is only a guide.



As the rich and successful observing night with the new Acuter Maksy 60 telescope concluded, a beautiful golden sunrise appeared in the East with noctilucent appearing clouds, flanked by the tallest skyscraper in Taiwan located nearby - Taipei 101 (with 101 stories) towering at a height of 1,667-feet and scientific antenna dishes for various satellite and weather studies. The skyscraper is so tall, it often can be seen rising up into the clouds with the top section completely obscured and the bottom visible. Three such skyscrapers placed end to end would reach a full mile into the sky. The spectacular skyscraper sports a tower at the peak which is lit according to aircraft and airport rules and regulations. This is ideal for use as an artificial star and for calibrating finderscopes and checking telescope parametrics.

About 101
Its design incorporates a number of features that enable the structure to withstand the Pacific Ring of Fire's earthquakes and the region's tropical storms. The tower houses offices, restaurants, and indoor and outdoor observatories. The tower is adjoined by a multilevel shopping mall that has the world's largest ruyi symbol as an exterior feature.

Going to the Top Observatory
After the construction of Taipei 101, I was given permission to go up to the top of the skyscraper at the tallest point of the tower. The last part to get there is by taking the steps. The extra steep steps did not conform to what I expected to be USA building code dimensions and in my exuberance and excitement, I stumbled on a step and nearly fell all the way down. A couple security agents probably almost had heart attacks! I finally made it up to the top where it was extremely windy, cold and dangerous, feeling that a strong gust of wind could pick me up and send me sailing out across the sky! But the risk was well worth it - the view was spectacular! Some time later, all people were prohibited from going outside to the top so I had a very lucky and exciting experience.

Planet Saturn Blasts into View - Celestron Nexstar 6-inch SE

 

Saturn from decades ago, had a different ring tilt - more edge on.

Planet Saturn Blasts into View - Celestron Nexstar 6-inch SE

As the story goes way back in the 1960s, I was taking classes in Jr. high school and a friend was pacing his new Criterion 6-inch reflector telescope that evening along with the Pastor's large refracting Unitron telescope. I was experimenting with the paramount invention of a new film developer, with the resolution of Acufine and the contrast of Metol. I asked to take a couple of photos of the planet Saturn through the telescope, not expecting much of anything, and he said, sure ok. When the negatives were developed, the results were mind blowing!

Seeing conditions were exceptional that night when I attached my Praktina FX camera with a roll of film, Kodak Tri-X emulsion,  and snapped very few Saturn photos which were later developed that night in the astro photographic darkroom. When the negatives were printed, I was stunned and completely blown away as they had the appearance of an observatory telescope photo taken with an aperture of a much larger size. The ringed planet was obviously at opposition, closest to the Earth and the view was crisp and clear with many divisions in the rings clearly visible.

Now, with Saturn and the rings in a different angle of tilt position, more open to face on, it begins its long journey towards another apposition, and the nostalgic telescopes comes to mind. This time, the telescope is a high resolution catadioptric Celestron f/10 Nexstar 6-inch SE on an altazimuth tracking mount with GOTO features.

Astroimaging Venus & Celestron Nexstar 6 SE

Astroimaging Venus & Celestron Nexstar 6 SE

Venus, along with three other planets (Mars, Saturn and Jupiter) are now increasingly well positioned, rising in the Eastern sky, for observing and astroimaging. The totally new powerful Celestron Nexstar 6 SE telescope is being prepped and pruned for planetary visual observing and electronic digital photographic astroimaging. The 6-inch catadioptric has ultimate superb optics and calibration and is being run through the paces as an indoor telescope viewing through a single pane of high quality white window optic for observatory convenience.

On the morning of Wednesday, April 6, 2022, the telescope was positioned by the window but initially not close enough. Once it was moved very close to the window, the sky field of view was increasingly wide enough to take in the planets. Jupiter had not yet risen from behind a tall skyscraper to the left, but extremely bright Venus was an easy centered target. Dimmer Mars and Saturn to the upper right were more difficult to locate given all the extreme light pollution, air pollution, and upper atmospheric haze.

This marks the beginning of a spectacular lunar and planetary observing and astroimaging season with a new telescope that's very easy to align, fast & efficient to use, and a breeze to transport.
