My wife and I were camping at Bottomless Lakes State Park in New Mexico in December and the skies were pretty dark there. I was able to do astrophotography just about every night. My best results came from the Orion Nebula. This picture is a combination of many different exposures of varying seconds and ISO settings. The final faint nebulosity was acquired with 6 subs of 120 sec each at ISO 1600. The trapezium area consists of 5 subs of 5 sec each at ISO 100. There are probably 4 more intermediate exposures in the final image also. Processed in PS CS2, Noise Ninja and Carboni Tools were all part of the process. Acquired with 9.25" Edge HD Celestron on a CGEM hyper tuned by Ed using a Canon XSi modified and guided with SSAG on an old AP 80mm guide scope. Hyperstar III was the key to making it all happen! BYEOS, PHD also played a significant role in focus, frame, acquisition and guiding. Deep Sky Stacker used to get the various images for layering.
