I'm only just starting to learn how to use my new Celestron Advanced VX EDGE HD 8" telescope (surely the longest name ever!), and last night had a go at photographing Comet Jacques, as it enters the northern sky. I'm still someway off getting a really good polar alignment, so I was limited to quite short exposures. This is a stack of 8 x 8-second light frames, with no darks, flats, or anything, taken at the f/10 prime focus with the 5D MkII at ISO6400. I only cropped the edges to get rid of stacking artefacts. Limiting magnitude is about 15.4.
