On July 30th, the Moon was not much of a factor and I decided to go after a reflection nebula. IC 5076 is definitely on the more obscure side of things but it is located in Cygnus a little North of the North America Nebula, NGC 7000, and so is well placed this time of year. In the same field is NGC 6991, an open star cluster that is rather poorly separated from the field. I ended up with an hour of luminosity data, and a total of 4.5 hours of RGB data (90 minutes in each channel).

Since this isn't imaged very often, it doesn't have a common name that I am aware of. But to me, it looks like a swallow because of the subtly split tail of the nebula. Hey, someone has to name these things!

NGC 6991 is centered to the left of the nebulosity and includes the area where IC 5076 is located. There are two distance measurements given in Simbad, one for 700 parsecs, and the other for 1400.

IC 5076 is thought to be some 5700 light years distant (1750 parsecs) according to Wikipedia. The bright star located within that is causing it to shine is HD 199478, a variable star that varies between magnitude 5.65 to 5.84.

Here is a version that was cropped to 1600x1600 and then reduced to 800x800 for Cloudy Nights.

Beautiful image!  The diffraction spikes really make this one.

Beautiful as always. I do think you could get away with just a little more noise reduction, though. Your data quality is so good, a nice light pass of TGV would probably do wonders.

Nice Image, well done. GC are my favorites for visual, but once I get my AP setup I think I will have to hunt M13 down.

Thanks Richard, Adam, Terry, Jon, Warren, Rick, and Cherokawa. I was really stepping out on a limb with this one with little idea of what to expect.

MR, you seem to always find lesser known targets that end up looking rich and inviting - well done!

Beautiful capture there. So much dark red dusty nebula during the summer, it is nice to see a bright blue target captured so well. It really is a great match for your fov and scale too.

As always, love the processing. Even the big diffraction spike adds to the image..  you take a lot of unusual targets MR.

It comes with the territory when one dwells in an alternate universe :p

True. :) My alternate universe is calling for some clear skies tonight. I'm not convinced it is actually going to happen yet, but I need to start thinking about what the universe might reveal tonight.

Terry thinks you are in an alternate universe but I think your obs is a satellite above all the weather, pollution and other **** conditions that us normal imagers put up with :)  Again, I really like that you are coming up with unusual targets! Well done, as usual.
