This is a nice star forming region in Cepheus, well placed in late fall. It's darned dim, with a lot of H-alpha (red).
Details: 37 * 5 minutes plus 36 * 5 H-alpha for a grand total of 6 hours. Equipment: SBIG ST-8300m (monochrome) CCD camera with the FW8-8300 filter wheel, Astrodon narrowband 36mm filters, and the Takahashi FSQ-85 telescope with reducer, AP 900GTO mount. The Ha frames were used to enhance the red channel and luminance. This object, as noted, is very dim... About 3 times the exposure would useful to show all the detail in this object, though I think the new version goes deeper than the older one below.
This is a nice star forming region in Cepheus, well placed in late fall. It's darned dim, with a lot of H-alpha (red), along with a few blue reflection areas as well. I finally (2008) got a chance to stack 3 sessions worth of pictures on this, with at least 39x4 = 152 minutes total exposure.
2005 Night: Prime Focus: 20x4min = 80 minutes exposure at 800 ISO. Temps were around 79 F most this night, which is a major disadvantage when using my uncooled DSLR. Canon EOS 20Da (unmodified), ISO 800, Takahashi TOA 130 (a 5" APO refractor), and Astro-Physics AP 900GTO mount.
