Cassiopea. Canon R6 astromod, 50mm F/1.2L. 3hrs

F/1.2. Maximum aperture open. Near Moscow. The Milky Way is not visible to the naked eye. It's surprising that anything showed up in the photo at all. The stars at the edges have "spikes" parallel to the frame edges—this is due to the slightest sensor tilt (a few microns) and the very fast F/1.2 aperture. Had to crop. Processing: PixInsight. WBPP failed with an out-of-memory error (too many files, not enough RAM). Had to process using the LN file (LN reference generation). Crop. Graxpert BGE. BlurX, NoiseX, HT_Stretch, StarX. Starless: Graxpert BGE, red mask.
