First try from Bortle 6 backyard in -10C with the SSA GTI (2024-01-15) with my Canon 600/4 III + Sony A7RIII; the stars were perfectly round. I started with 15 sec subs for one hour and then 30 sec subs at ISO 800. But apparently thin high clouds had rolled in, so even though the stars looked good at 30 secs, the entire image had a light cast from the clouds. So had to make due with 123 of the 15 sec subs I captured initally. Only used the SSA's built in guidance, but that was enough to give about 80% keepers. I'm impressed by how well the both the lens and the SSA worked at 80% of max load.
Still very new to Pixinsight, so not very happy with the postprocessing, but it's a start...

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.
