Acquisition type: Lucky imaging

This is my first time imaging Saturn this season. It reached it's highest point at about 2:00AM local time. I used a new telescope for this and it was my first time imaging with it. It is a Obsession 20" F/5 Dobsonian reflector (made in 2002). I had some challenges to overcome and definitely think I will be able to improve on this with such a large telescope. I didn't have enough "in-travel" on the focuser with the full imaging train, so had to shorten things up a bit. I think I can move the primary mirror closer to the secondary mirror to gain a bit of room to focus with full imaging train. We still had smoke in the sky an the seeing was poor and it was quite windy, which made the telescope vibrate quite a bit. But I did manage to get a half-way decent image. The large size of the telescope should allow me to get better results in better conditions. Also, I never used my atmospheric dispersion corrector on this type of telescope and got the horizontal reference wrong, so the color balance is significantly off. Still, I managed to resolve the inner C-Ring of Saturn better than I ever have before.

Obsession 20" F/5
D=508mm, L=2,556mm
Televue Powermate 2X
Effective focal length = 5,112mm @ f/10

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
