Comments: | This is my first image with my recently acquired ST-8E and new CFW-8. The greater dynamic range of this camera seem to bring out more detail in images of the same duration over the ST-237A. All equipment on a CI700/SkyWalker/2 upgraded EQ Mount. Reprocessed on 04/19/03 with new techniques learned from Ron Wodaski's CCD image camp at New Mexico Skies. |
