Made this pretty picture last monday!
There are some weird circles present, only when using the L stack. I assume they are because of bad flats, but if they could be something else, please tell!
Equipment used:
Omegon 2845/355mm RC telescope
EQ8r-pro mount
0.67x reducer
ASI2600MM
ZWO EAF
ZWO 7×2" EFW
Antlia LRGB filters
Lacerta flatbox
All of this inside of a ScopeDome 3m dome, connected to a mini pc with NINA.
Data:
7x180s L
6x240s RGB (6 frames each)
Processing:
Stacking in DeepSkyStacker with Bias, Dark, Flat, Darkflat frames.
Removed gradient in graxpert
Used 1.0 strength AI denoise in graxpert
Stretched each stack in Siril
Combined frames, linear match & align in Siril
Final stretch in Siril
Finished with wavelet filter
If you have any questions or tips they'd be welcome!
