My DSLR capture settings are determined on where I’m imaging from and what object I’m imaging
In Sydney ( bortle 7 to 8 ) I’m currently using lots of short subs ( 30 sec) at ISO 800 on M42 but down at my holiday house 220km south of Sydney ( bortle 2 to 3 ) I used longer subs (60 to 80 sec) at ISO 800 / 1600
I find the “sweet spot” for the Canon 600D is generally ISO800 on a majority of objects
I totally concur that DSLR’s were never designed nor do they perform well for long long exposure astrophotography.On 2 to 5 minute subs my DSLR’s sensor temperature was reading 45 to 49 degrees which is counterproductive
Cheers
