M55 in Sagittarius


Scope: StarMax127 f/3.2 Location: Blair Valley - Anza Borrego CA   10/4/2002 Camera: Vesta 690

Exposure: 16 x 50 sec color frames with IR block filter

This image was taken with the extreme focal reduction (from f/12.1 to f/3.2) I was experimenting with using two focal reducers - spaced. As you can see from the image there is a circular coma pattern on the edge stars. I still enjoy this image despite its flaws so I put it on the site. Horizontal FOV is 26'
