ASTRO: SH2-235 and PK 173.7 +02.7

Emission nebula Sharpless 2-235 and Planetary nebula PK 173.7 +02.7 are
among a field of emission nebulae in Auriga. I originally intended to image
the whole field with my ED80 refractor, but then decided to take a close-up
with my 10" Meade ARC. Maybe I'll manage to do the widefield later this year
(or next).
This is a Ha:G:B image. I also took some OIII frames, but they had almost no
signal, in neither of the nebulae.

Taken from the middle of Berlin with a 10" Meade ARC at f/5.7, SXV-H9
camera, 78x5 minutes for Halpha, 4x5 minutes each for green and blue.
