I had my first chance to try out my new Hyperstar V4 with my 11″ Celestron SCT (Elf). With this configuration, Elf becomes an 11″ f/1.9 lens with a focal length of 532mm.
This was not a night for long integrations. It was just a shake down cruise. Below are some images of, top to bottom, Omega Centauri, Centaurus A, and Markarian’s Chain. In this configuration, the camera has a 2 degrees by 1.4 degrees. Each of these images are 50 sixteen second images combined. Minor stretching was done but no other post processing. I want you to see it almost as it came out of the camera. Click for a larger view.
Here are a couple images taken in the early hours of Saturday May 30, 2020 from the River Ridge Observatory. The Moon didn’t set until 2 AM so I spent several hours essentially piddling around and then stayed up all night. I used my Canon Rebel 800D with a 50mm f/1.8 lens riding on my 11″ SCT while it was busy imaging something else. I used a so called “city light suppression” filter to try to mitigate some light pollution. By the way, this was to the south from the RRO and Little Rock was to the southeast. Each image is a combination of six 5 minute frames then processed in Photoshop. My Photoshop skills are still a work in progress. The CLS filter tends to cast a green tint so that had to be removed. The dark circle in the lower right is the telescope.
Here is a picture of most of the constellation
of Orion taken with my Canon 800D and a 50mm lens at the River Ridge
Observatory Saturday January 18, 2020. My friend John Reed did the post
processing. I used my Celestron AVX mount as a tracking platform and took 12 5
minute subs for one hour of data combined in DeepSkyStacker. The ISO was set at
800 and I was using a “city light suppression” filter to try to mitigate the
My main goal was to capture Barnard’s Loop
around the Orion Nebula and I did that. Inside the loop, near the center you
can see three blue stars that make up the belt of Orion. “Attached” to the
bottom star are the Flame Nebula (below and to the left of that star) and the
complex that includes the Horsehead Nebula (below and to the right of that
star). Further to the right is the Orion Nebula. All of this nebulosity including
the big ball of fluff on the left is part of the huge Orion Molecular Cloud
Complex. Only some of it is illuminated
by nearby stars, stars being born there now.
In the lower left quadrant is the star
Betelgeuse, in the news recently because of it dramatic dimming. It’s still
bright but is more like top 25 bright instead of top 10 bright. In the upper
right is the bright blue star Rigel.
