The Veil nebula complex is one of the features of the constellation Cygnus. It is another supernova remnant, consisting of gases blown off by an exploding star. Its huge size indicates that the explosion occurred long ago. North is straight up in this image.

| Scope |
Nikkor 180 mm f/2.8 ED lens at f/2.8, piggybacked on an A-P 1200GTO mount. Camera: SBIG ST-10XME with CFW-8A color wheel. MaxIm CCD camera control. Guiding was via an ST-4 on a separate guidescope. |
| Exposures |
Ha 3 nm Custom Scientific filter; 12 x ten minutes for 120 minutes total |
| Processing |
Frames were calibrated with darks and flats, hot pixels removed, and gradients corrected in MaxIm DL. The frames were then registered and combined in Mira Pro. Two iterations of Richardson-Lucy deconvolution were applied in CCDSharp. Levels and curves were then applied in Photoshop v7 followed by mild unsharp masking. |
