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.

Veil Nebula
Supernova remnant in constellation Cygnus

Image is in Natural color palette from the emission of ionized elements, 
R=Hydrogen + Sulfur, G=Oxygen and B=Oxygen + Hydrogen.

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.

A rarely imaged object, the Sharpless106, Sh2-106


Sh2-106, The Hourglass nebula, an emission nebula in Cygnus
Ra 20h 27m Dec +37° 22′

Image is in Natural color palette from the emission of ionized elements,
R=Hydrogen + Sulfur, G=Oxygen and B=Oxygen + Hydrogen.

A closeup




INFO

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 .

The second image of the Autumn season 2013. Sharpless 132




Sh2-132, an emission nebula in Cepheus
Ra 22h 19m 20s Dec +56° 06′ 00"

Image is in mapped colors, from the emission of ionized elements, R=Sulfur, G=Hydrogen and B=Oxygen.

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.
