IC 1396 Area CCD Image
This is a star forming area around 3000 light years from Earth. Note the dark dust clouds. Dark Nebula Barnard 161 (B161) is on the mid-lower left, along with LDN 1110, 1112, 1124, 1121, 1117, and several more. Image composed of 18 * 4 = 72 minutes exposure using Takahashi TOA 130 Telescope (a 5" APO refractor telescope) with the reducer, AP 900GTO mount, QHY8 CCD Camera. Other pictures from the camera are are here. Images processed using my Astronomy Image Processing Workflow. Compare with my older DSLR image later on this page.
34*4 minutes = just over two hours total exposure with a Nikon 55mm lens on my modified Canon 20Da DSLR. Dark Nebula Barnard 169 is visible below IC 1396; see this in the telescope shot on the Dark Nebula Page. Sharpless SH2-129 (SH-129) glows above left. SH-132 is below right, SH-134 is to the left of that. There are many other dark and bright nebulae in the frame. This image is from the: December 2010 Astronomy Pictures My notes say: Barnard 169 is the dark area below right while Barnard 160 is the most prominent dust lane above.
