Description

First time trying my Nikon DSLR with the 8" astrograph. Terrible coma even with the Baader MPCC. I must have the back focus wrong. This image is without flats or bias. I don't normally shoot darks with the Nikon but bias are a must. Significant vignetting as well so next version will have flats and bias.

Battery died shy of the 2 hour mark which is just as well, the nearly full moon was flooding the sky towards the end.
