Here is my first deep sky shooting exercise. I used a pre-assembled astroberry distro. Somewhat surprisingly, the ASTAP stacking software included in the package did not even agree to open the RGB24 TIFF format that was in the default settings of the imaging software, so my stacking intentions remained next time.
