The Veil Nebula in Cygnus, in grayscale Hydrogen-Alpha.  An earlier film attempt, a wide-field full-complex color mosaic, and a more recent bicolor image are also on file.

Location: Texas Star Party 2004 near Fort Davis, Texas

Seeing: 8/10

Transparency: 9/10

Date and Time: May 19, 2003

Equipment: Tak FSQ-106 on Tak NJP mount

Camera: SBIG STL-6303E, self-guided

Filter: Custom Scientific 5 nm H-alpha filter

Exposure information: Grayscale, 60 minutes (10 min sub-exposures)

Processing Information: Calibration, deblooming, alignment, and Sigma combine in MaxIm 4. Curves, Levels, and selective, iterative Unsharp Mask in Photoshop CS.

Exposure Notes: This was my first attempt at using the 5 nm H-alpha filter that is integrated into the STL-6303E. I didn't have as difficult a time finding a guidestar as I originally feared.

About this Object

Perhaps my favorite visual object! This area of the sky is huge, so large in fact that placing all three segments of this supernova remnant on the CCD chip is rarely done without some form of mosaic. In this case, a large format CCD coupled with a short focal length astrograph can produce a thrilling, wide-field view of most all of the nebular regions of this complex.
