Description

Sharpless 2-27 is a large and faint HII area in Ophiuchus, maybe some 6 x 6 degrees in total.  This framing  covers just part of this area including LBN 20-22, 32 and 35.

It's a 2 panel mosaic, but I had to crop a fair bit due to some gradient / background artifacts that I can't fully explain at the moment, although they are repeating in my images, so something is going awry somewhere. This area is fairly low in my skies and the HII area is faint, so the end result is perhaps a bit murky, although there is lots of other dust around too which us contributing to the effect.
