Cygnus - Sadr Region




I have had this camera for over 5 years and have yet to really discover it's full potential. I have been focusing more on how to squeeze the most out of it. I decied to lower the ISO from 1600 to 400, add some solid guiding via the C8 and QHY guidecam as well as ad bias calibration. I'm quite pleased with how the end result came out! It is minimally processed after all new darks, flats and new bias frames added to the stacking in DSS.





Included in this region are the following:
