Perseus Double Cluster

6" Newtonian, Canon 350D, 13x60seconds
First picture using Coma Corrector

Newtonian reflectors suffer from 'coma'. Stars at the edges of the field are elongated and look like small comets.
Compare these two enlarged images. They are both taken from the top left corner of an image.

Andromeda Galaxy M31
6" Newtonian, Canon 350D, 9x30seconds, ISO 1600
First try at ISO1600. Comparison with ISO800 is difficult because there was no moon

NGC7662 Planetary nebula in Andromeda, the 'Blue Snowball' nebula
6" Newtonian, Canon 350D, 9x30seconds, ISO 1600 Small and very bright, but few features discernable

NGC404 Elliptical galaxy in Andromeda
6" Newtonian, Canon 350D, 20x30seconds, ISO 1600
Found by accident when using Beta Andromeda to focus the camera.

The negative image shows the galaxy clearly and also stars down to magnitude 16
