This is a combination of 5 images, each of 480 seconds The images were taken with a Pictor 416 attached to an Meade 10" F/14.768 telescope. A Pictor 201XT was attached to an ETX for guiding. Each of the images was corrected with a dark frame and a flat field. After combining, the image was logarithmically stretched.

I used a Meade Model 140, 2x barlow. The effective magnification with the 416 was 2.34x.
