Hi guys, I´m starting astrophotography, I have been reading about ISO issues, but can´t find a solid info, sometimes I found contradictory answers related to this matter in different forums.
As far as I know, higher ISO doesn´t mean more details, and each camera has it´s own proper ISO in astrophotography (noise-signal), so, questions:
-why then shooting higher ISO than 100/200 if it´s doesn´t add details and apparently it´s better for noise except for certain older cameras?
-The "optimal" ISO for each camera is applied in the short time exposure like 1 min or only in long exposures? that´s my case, 8 bortle sky and no guiding so I´m stuck in 30/60 sec maximum.
I have a Nikon D3200, 200 ISO seems to be best for my camera according to http://dslr-astropho...nikon-cameras/
So guys, Do I have to shoot on ISO 200 even with 1 min max exposure and light pollution? what would you suggest?
