NGC 7320 Peg 2.2

2010:08:31:01:47:52

This is a combination of 20 images, each of 30 seconds The images were taken with a Alta-U16MD7D9 attached to an OGS 20" F/8.1 telescope. This used 2x2 binning. Each of the images was corrected with a dark frame and a flat field.

I am still playing with the U16 on the OGS. In particular, I am concerned about flat fielding the images (since there seems to be a lot of reverse vignetting). Here you can see the glow at the corners and some residual dust bunnies.
