This Squid Nebula uses 12 Light (300 seconds), 20 DARK, 20 flats, 20 DARKFLAT, and 20 BIAS.
Telescope time rental services say the darkness of 21.5 SQM at night. Perhaps I think it was taken with that darkness, but the left and right brightness is imbalanced as if it were the effects of light pollution.

The camera is ASI2600MC Pro and the telescope is TAKAHASHI FSQ106-ED F/3.6.

APP Version 1.083.3

Thank you.

Seems like there was some, maybe the moon? You can easily get rid of this using the light pollution tool. 🙂 I would also suggest to update to 1.083.4 as quite some fixes were made in there.
