This image was taken at a WYAS open night on 19th September 2012 using one of the new piers on the Telescope pad. This was taken using my 8" Celestron U2K SCT scope unguided with a Canon 40D DSLR.
The colour image of M27 was only the second time I had attempted to take images using a new imaging set-up at home. The image was taken with a Televue 102 using an Atik filter wheel containing Baader LRGB filters. 20 mins L, 15 mins R, 30 mins G and 30 mins B (all calibrated in MaximDL. Lodestar guided images.
The narrow band images were taken using the same set-up but using Baader narrowband filters 30 mins H-alpha (red), 10 mins OIII (green), 10 mins H-beta (blue). Many images taken were spoiled by strong wind.
