The Great Wall of Cygnus

 Due to very cloudy weather I have remade some of my older photos, this time the Cygnus Wall has been remade. This is a combination of several older images from 2008, 2010 and 2014. Two different longer focal length telescope was used, The Meade LX200 GPS 12" and Celestron Edge 11". Beside long focal length images material from shorter focal length optics was used from the Canon EF 200mm f1,8 and Tokina AT-x 300mm f2.8 camera optics. Older material was taken with the QHY9 astro camera and after 2014 Apogee Alta U16 camera was used. Total exposure time is around 30 hours.

Info about imaging technique

I have used my new processing/imaging technique VARES for this new composition (VAriable Resolution Imaging) It's really powerful toolset when data from very different focal lengths are combined to a single high resolution image. The principle is that the high signal/noise elements are from the long focal length instruments and the low signal/noise data from the short focal length optics is used to boost relatively featureless and very dim image elements.
