This image of planetary nebula M27 was taken on the night of 7-Sep-2013. It is a combination of 22 two minute exposures at f/4.9, processed with 20 dark frames, 20 flat frames and 50 bias frames. This composition represents essentially the entire field of view recorded by my Canon T2i at the prime focus of my 8 inch newtonian reflector telescope. This is the first image in this gallery for which the flat frames were taken with an artificial light source, a light box that I built myself.

All image processing was done with PixInsight software. The imaging telescope was guided with a Meade DSI camera attached to the prime focus of an 80 mm f/11 refractor. Guiding signals were fed back to my Atlas EQ-G mount by PHD Guiding software and the EQMOD driver. A Bahtinov mask was used for focusing. Focusing feedback and shutter control were accomplished with BackyardEOS software.
