NGC 1365 Great Barred Spiral Galaxy Bortle 8 Sydney

Just wanted see how the new 2600MC camera would perform imaging a dim galaxy under Bortle 8 Skyglow with limited data
NGC 1365 Great Barred Spiral Galaxy in Fornax
Magnitude 10.3
Size 5’ x 4’
2 hours of data over 2 nights ( 90 sec dithered guided subs )
Conditions ( seeing ) were average with some high cloud passing later on both nights
No darks or flats
6” f6 newt on an EQ6-R mount
ZWOASI2600MC
Ascom driver set at HDR ( gain 0 offset 50 )
Cooled to -15C
No filters used
Stacked in DSS
Processed in Startools v1.6 Linear data set

Stacked image ended up being a noisefest but managed to extract some sort of image out of the mayhem
All things considered the camera performed well
Another 2 or 3 hours definitely would have improved SNR and resulted in more detail

2 versions original frame size and cropped

You can make out a few faint fuzzies in the field from the original version

Comments most welcome

Thanks
