M27 With ST-237A, M27 is also known as the Dumbell Nebula

Austin, Texas

This is my first try at using a cooled CCD camera. The image was taken with an SBIG ST-237A Black and White CCD camera with Red, Green and Blue filters. 10 two minute pictures where taken with each filter and 10 luminance pictures with no filters. The 40 pictures where aligned and stacked in Images Plus. The scope used was a Televue 85 refractor on a Losmandy G11 mount.
