NGC 7822 - DSLR + CCD
The top image consists of 27 * 4 (108 total) minute DSLR images combined with 28 * 5 (140 total) minute CCD images for 248 minutes total exposure time. More details below. CCD image captured on this trip to the Davis Mountains.
Above: 140 minutes total exposure CCD image. It's covering a wider area than the combined image on the top. Takahashi TOA 130 Telescope (a 5" APO refractor) with reducer, AP 900GTO mount, and QHY8 CCD Camera & normal workflow. CCD image captured on this trip to the Davis Mountains. Below: Compare with DSLR image.
I think this is mostly Cederblad 214 and some of NGC 7822 but am not entirely sure. I found this in "The Sky" while looking for something to shoot in the cloud-free part of the sky 12/29/2007 at Starry Nights/Wimberley. Update: apparently it's also Sh2-171!
27 images of 4 minutes each = 108 minutes total exposure. December 29, 2007. Canon EOS 20Da (unmodified), ISO1600, Takahashi TOA 130 (a 5" APO refractor) with reducer, and Astro-Physics AP 900GTO mount. My current image processing workflow is here.
