ASTRO: another image of M-2
This is my image of M-2 taken in 2002 using my ST-9E camera. It is a
10-minute exposure processed with DDP to bring out the full extent of the cluster. This type of processing destroys the photometric accuracy of the image, i.e., the true star brightnesses are lost. The cluster looks a lot more like the color image I posted earlier when viewed visually thru a 20-inch scope (either the RC or my 20" F/5 Dob). George N |
