Description

I had always taken 5 min subs, and built my DSLR dark library on that premise. My histograms were well over to the right, so I thought I would experiment with shorter exposures and a faster lens. I used my 85mm Nikon lens at f2.8 (it did OK at this speed, but not great). I took 57 1 minute subs through the Astronomik LPR_CCD clip filter and 56 2 minute subs through the Astronomik Ha clip filter. Quite a surprising result from Bortle 8 skies and less than 3 hours of data I think!
