Very nice. If you have any details regarding exposure, #frames, etc, that would be interesting since I'm just now going up to astro learning curve with my new star tracker.

The shot consists of 6 stacks of 4 x 8 second exposures in portrait mode f1.2 ISO 5000. Each group of 4 was stacked using Sequator, then the 6 shots were stitched into a panorama

Thanks, that's a very interesting exposure time. I'll have to give it some thought.

I have found with the 61MP of the A7CR that I need to limit my shots to about 10 seconds with my 16mm lens, and 8 seconds with the 35mm lens. Of course stacking them e
helps reduce transient objects like satellites, and noise from the stacked shot while expanding the overall exposure time. The effective shutter speed for each of the shots in the panorama was 32 seconds. For panoramas I limit myself to 4 or 5 exposures per panel, but for single frames I would usually stack 10 shots. Of course with a star tracker mount my exposure times would be longer.

Thanks, I thought you were using a star tracker. That makes more sense.
