Seestar S50, UV/IR cut, mosaic mode, 9 (1.7x framing) panels, 10362 10s subs for a total of 28 hours, 3-4 hours per tile over 19 nights in Bortle 6.
This was made using the mosaic mode to generate enlarged mosaic panels for each area, then stack them into one. In terms of native Seestar FOV this whole area is roughly 30 to 50 panels, depending on how all overlaps are considered.
I chose this area for such a large project due to its sheer brightness, with tens of thousands of stars that the S50 can resolve, so each panel wouldn't require very deep integration, making it possible in a reasonable amount of time.
I thought doing a mosaic of this size with the Seestar was all fun and games until I realized it was going to turn out a bit of a gradient fest, with a particularly stubborn inconsistency in background brightness that seems to be a mix of light pollution (this area peaks at 32 degrees for me, and the Moon was involved in some of this data) and the way GraXpert handles it, I didn't have much luck with other tools either, and processing brought it out before I could notice it earlier. So this is mainly caused by the wide variations in brightness across different nights, nearer towards the horizon, especially as some subs approach the end of astronomical darkness. So yeah, its not what I'd considered a polished image in terms of color gradients and noise artifacts, but I absolutely expected the data to be a pain once all stacked together, so I wanted this to be more of a project to test how far the Seestar could go with its handy mosaic mode, even covering areas larger than it normally allows.
