After using a Canon 600D DSLR for just over 3 years , I can’t believe how good this camera is under heavy light polluted skies using the Duoband filter
Using my DSLR the maximum sub length in Sydney was 60 to 90sec and even then the subs were washed out with all types of noise and obviously worse in summer.
Also I’ve only been cooling the camera to -10C and according to the specs it’s capable of up to -45C below outside ambient so dark current can still be greatly reduced even though there’s minimal noise in the subs in the first place
So much more experimenting and testing to do and I haven’t even got down to my dark site yet
Totally gobsmacked with this camera !!!
