And here they are photographed with my Canon DSLR attached to my ST80 with X2 lens attached. I have enhanced the colour a little, mainly to compensate for the loss when I reduced the original image to make it fit on this page. I think this is more like it would appear to the eye in a dark sky. Date and Time: 16th September 2010 23:30 UT Camera: Canon 1000D DSLR Telescope: ST80 with X2 lens. Capture: K3CCDTools. Exposure 60 sec, at ISO 1600 Processing: PhotoImpact. Gamma 1.8, contrast 10, Focus Magic 1, 100 |
