Sharpless 171

A plain H-alpha image of the central region of Sharpless 171 (Sh2-171). This busy region is surrounded by another ring of gas, not visible in this frame.

Composed of a total of 4.5 hours of 10 min exposures from my backyard. A first test of the 0.79 Reducer from TS… stars are looking good already. I will try to gather OIII data as soon as I get some clear skies.

Setup: APM 107/700 Triplet, 0.79 Reducer, ATIK 460 EXm Site: Langen, Hessen, Germany
