Barnard's E 22/08/07

The above image of B142/B143 (Barnard's E) in Aquila, which was taken on 22nd August 2007, is actually a stack of 3 x 150 Second exposures. Although the sky transparency was good, the seeing wasn't particularly brilliant and so a lot of processing had to be done on the individual images as well as on the final stacked image. Equipment used: Canon EOS 300D, Sigma EX 150 mm APO lens, 1.4 x APO teleconverter, Vixen GP photo guider. Exposure details: 3 x 150 Seconds @ F/5, ISO-800. Alan Tough
