How many dark frames do you take and average?
And any dithering involved?

Actually Brian, looking at my notes, they were all done in a rush , and less than an hour a piece. All in the same nighht. Altair Astro RC8, with Revelation 0.75x reducer, QHY10, EQ6. Guided with 60/285 finder, PHD2 and Altair GPCAM2 AR0130. 7 x 360s , darks and flats. Taken with ATP, calibrated in ...

I am now very keen to try out your methods on my altair mono and colour cameras, and my old QHY10 CDD. Is there any chance you can provide a little written explanation to your thou...
