Description

Another full disk mosaic now from the previous day. 5.3 ms exposure times with 125 gain (31%). Best 400 frames are stacked for each subframe (total 31 subframes). 

Autostakkert4! was used for stacking the videos with flats and ImPPG was used for initial processing. Mosaic composition and processing were made in Photoshop where I also sharpened the image with USM and high pass filter to the final status and added colors.
