Description

M42, M43, NGC 1977 in Hydrogen Alpha wavelength (7nm).

It was a bit murky, and the bright moon made most targets unsuitable, but Orion strutted his stuff over the house and made such an offer of a quick picture it was hard to resist. Skywatcher 150ED and Atik 11000, Baader 7nm Ha filter.
