The crescent nebula in Cygnus. Taken over two nights, first in H-Alpha light, then in filtered Red Green and Blue light. Total exposure 1.5 hours for the hydrogen alpha light and 15 minutes for each color.
The color light was taken last night, the H alpha a week prior. Both shot through a 5" f7 refractor from Verona on a crescent and subsequent first quarter moon nights.
