VdB 152 is a reflection nebula at the tip of the dark nebula Barnard 175. The small bright red object just under VdB 152 is the Herbig-Haro object HH 450 (a proto-star.) The red tendrils are a supernova remnant. A pretty cool field
It took me quite a while to process this one because it was difficult (28 hours of Ha was still very noisy) and also because I was testing a new version of PI that will be released soon. It has some pretty cool new features and my ColorMask script is now part of the standard version

There are still some minor nits that annoy me and I'll probably go back and do a repro. Feel free to point out all the obvious faults that I've missed
Cheers,
Rick.
