Acquisition type: Lucky imaging

Last year's Saturn two weeks after closest approach to Earth.

Integrated eleven four minute runs to produce this view of the ringed planet following 2021 opposition on August 2. Was blessed with some steady seeing between 10 and 11pm local time as Saturn neared its maximum elevation of 73.5°. Transparency was variable with high level cirrus cover.

I decided to go easy on sharpening and saturation for this treatment, resultant image is a closer analogue of telescopic appearance with subtle colour differentiation between atmospheric bands all the way towards the North Pole.

The Hexagon feature is now difficult to resolve due to a much decreased tilt of the rings compared with 2020. There's enough resolution in the data to show the Encke Gap, C ring and slight rippling of the NEB boundary. It was also a bit too late to observe Seeliger effect one fortnight pass opposition. I haven't been taking many images of Saturn in 2021 so reasonably happy with this effort. Other captures are from April, May and June with the planet sporting a smaller apparent diameter.

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.
