Description

The Veil Nebula, sometimes called "The Witch's Broom" is in the constellation Cygnus. Some 5,000 years ago, give or take, a star went supernova and this image is a piece of the remnant. The full circle of the remnant takes up about a three degree circle in the sky equaling a space about six times the diameter of the moon. With instruction manuals, trial and error and plenty of help from experts on amateur forums, I point the observatory telescope to a pre-identified place using sophisticated, automated equipment and capture the sub images. William Herschel, on the other hand, made his own telescope and found the object for the first time in 1784. No digital cameras were involved.

This is my first attempt with the hydrogen-alpha (Ha) narrowband filter which took the place of the normal luminance frames and also was used to enhance the red. Somehow the blue that is in there did not quite show up.

With the Paramount ME I can get away with 5 minutes frames unguided. As of yet I have not been able to get TheSkyX autoguider to improve the outcome or not make a hash of the process.
