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 .

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



In this year it took some time to have a real first light for the season due to the weather up here 65N.
Image is exposed during several nights, 13.09 - 14.10,  between the speeding clouds.


NGC 6992
A portion of the Eastern Veil in constellation Cygnus.

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

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.
