Description

First mosaic try ever. Used my Rasa11" with ASI6200MM-Pro to make a 2x2 panel. 30 minute exposure per panel. Not quite aligned, so the end resolution is at 170 Megapixel. I converted it to 8bit to keep filesize doable

interesting is that the Mosaic stitching using distortion correction in PixInsight actually helped resolve some of the flatfield issues with my new, not completely calibrated, Rasa11.

I'll add some other NB channels sometime for just 2h of exposure a lot to see.
