An other supernova remnant in Cygnus, G65.3+5.7 SNR
This is a rarely imaged target. I haven't been able to find an other color image of it, showing the whole supernova remnant. This is also one of the most difficult targets, I have ever shot. Due to very dense star field, large angular dimension and a very diffused structure this is even more difficult target, than a Simeis 147 supernova remnant in Taurus. Total exposure time of 32h was needed to have this kind of "thin" image.
G65.3+5.7 SNR has about the same angular dimensions, than brighter and more famous remnant in Cygnus, the Veil Nebula. The angular dimensions are about 3x4 degrees.
NOTE, this image is updated at 20.01.2014. There is now a better H-a channel and the background is practically full of ionized Hydrogen, H-alpha.

Veil Nebula unveiled
The exhibition is over, lots of visitors and many photographic prints has been sold.
Many thanks to all visitors and buyers!
I have some new material waiting for publishing, even though the weather has been really bad up here.
I had some technical problems with my longer focal length instrumentation and I had to move back to use my wide field tools. Veil Nebula in this post has been shot with the Canon EF 200mm f1.8 camera optics.
There is now 13h h-alpha light, collected from years 2008, 2012 and 2013.

Info
Veil Nebula is a cloud of ionized gas and dust, leftovers from an exploded star. The star went off some 5000-8000 years ago at distance of about 1470 light years. This, relatively faint target, is difficult to image due to the large angular diameter, about three degrees, and a dense star field.
This is a second version of this object, older version can be seen Here.

There are not too many images around about this little fellow.
Sharpless 106, the Hourglass Nebula, locates in constellation Cygnus approximately at distance of 2000 light years. This is kind of a small object, an apparent size is about four arc minutes (Moon is about 30 arc minutes.) There is a young star at the center of the nebula, S106IR. The solar vind, a radiation pressure, from the young star is responsible for the gas cloud's hourglass like shape.
I think, there is a hint of the outer shock front visible in my image. It locates symmetrically at both side of the central nebula .

INFO
Sharpless 132 is a very faint emission nebula, it locates at the border of Cepheus and Lacerta. Distance is about 10.000 light years. This image covers about 210' x 160', that's about 3,5 x 2,7 degrees. Resolution is 3,79 arc seconds/pixel.
In this final version, a strong O-III area is visible as a Blue color in both color palettes. There is some S-II in the area too but it's weak.

First light for the Autumn Season 2013, NGC 6992

INFO
NGC 6992, the Eastern Veil, is part of the Veil Nebula, a supernova remnant in constellation Cygnus at distance of about 1470 light years. This is one of the more luminous areas in this SNR.
The shock front formed by the material ejected from giant explosion, the super nova, can be seen in this image.
