I like your picture very much, i´m a big fan of dark nebulas anyway. If you would get rid of the gradient (greenish looking in the left upper corner) it would be A+. I use Gradient X Terminator to do so. But there are other (cheaper) ways too.

There are so many other targets in Cepheus still waiting to be imaged. @frank Quote: i´m just wondering i couldn´t find your picture in one of the german speaking forums!? there is only a question of time. The gradient in the upper left corner may due light pollution, the gradient in the bottom left corner comes from my flatfielding. I think the rotating shutter of my camera is not precise.

Yes, dark nebulae pose a different challenge than "standard" nebulae. -Tom Post Extras:       J.P.M Post Laureate Reged: 11/14/06 Loc: 65"01'N25"47'E Re: Barnard 150 - Dark Nebula in Cepheus [Re: Thomas Davis]       #4162690 - 11/04/10 09:53 AM Edit   Reply   Quote Quick Reply   Darkies are interesting targets, good work with this one!
