Description

I thought this was very challenging to process, mostly due to all the noise there was to deal with - probably because of the short integration time. Clouds moved in and I had to toss out a lot of subs - a repeating theme this summer. Maybe I need more "Clear Skies" wishes .

Sh2-155 is an interesting H II region and stellar nursery in the constellation Cepheus. It lies at a distance of about 2400 light-years from Earth, and the cave portion is about 50 light-years across.

Clear Skies,
Mark
