NGC6914

Located in the Cygnus constellation about 6000 light years distant, NGC6914 is a blue reflection nebula consisting of VbB131 and VdB132.  

Surrounding NGC6914 are reddish areas of hydrogen emission nebula which provide a dramatic colour contrast to the blue nebulosity.  The contrast is further increased by regions dark nebulosity (LDN 899).

The stars are also a notable feature of the image since embedded within the nebula is the star cluster Cygnus OB2 which consists of about 100 class “O” (yellow)  and 2500 class “B” (blue-white) stars.

The image was taken with my Esprit 150 and represents 16.5 hours integration time. It is an LRGB image with a Ha blend into both the Red and Lum channels.

I prefer the original colour balance. Nice subject well framed.

Regards Andrew 

Thanks for the comment Andrew. In terms of the colour balance, I was drawn to change this when I checked the histogram levels which shows that the original image is quite unbalanced at the lower levels, however, I also like the "more blue" effect in the original.

I I think the credit for the framing goes to CCDNavigator (where you can preview the image for your given FoV) and ACP, for actually getting the object in the center of the FoV.  As an aside, CCDNavigator was recently made compatible with ACP Expert which enables you select objects to image through a view mouse clicks, which I really like.
