Photo description / processing

LDN 1251 is a complex of dark molecular clouds located in the constellation Cepheus. Dense interstellar dust obscures the rich stellar background of the Milky Way. Emitting no light of their own, these clouds appear as a "fish" silhouetted against the countless stars behind them.

I shot over several nights in August, September, and October. The weather this year doesn't encourage frequent outings.
