Messier M15 - NGC 7078 - Globular Cluster 25/09/2010 (Processed)
One of the first images, cropped and colour adjusted by Adobe Photoshop CS5. Taken through the Apogee 80 on the SkyWatcher NEQ6 mount, sidereal tracking but unguided for 30sec @ISO 800 in-camera JPEG with no in-camera dark and with no light pollution filter or field flattener.
M15, like M2 and M28, is quite small, so cropping has exacerbated the poor focus here. The globular nature of the objects is present but obscured by the lack of detail in the unfocused core. This object needs longer focal length for detail. Also see original unprocessed image.
Telescope - Apogee OrthoStar LOMO 80/480 without Field Flattener or light polution filter, Canon 400D DSLR, Ambient xxC not noted. Mount - Skywatcher NEQ6 Pro. Unguided. (Prime focus)
