Description

First light image with Atik 428EX. I'm pretty happy with the performance of the CCD except for the right side of the image is slightly out of focus. I swapped out the 414 with the 428 and kept the spacing to the reducer the same. I really didn't notice the problem until I looked at them in PixInsight. Maybe something isn't square now. I'll have to keep working on it.
