Description

NGC 6888, The Crescent Nebula. This is the first light with my new Starlight Xpress Trius-SX694 mono CCD with Mini Filter wheel and Astrodon filters. I was using a modified Canon 450D prior. I have got to say the cooled mono CCD's are a drastic improvement. Particularly when using the narrow band filters since I image from my backyard in a deep red zone inside a city. I am very pleased with this new imaging setup.
