The huge M31 didn't fit in the field of view, so I wanted to try assembling a mosaic. This is currently an "experimental," raw version. Even the existing material will be processed better. The experiment was squeezed in.

Mosaic of 4 tiles: 2x2. Exposure and calibration frames are the same for all tiles.
PS: 2 tiles were captured during twilight.
