Urban NGC6960 The Witch's Broom Nebula

Here is another urban effort taken from my light polluted urban driveway. The target is NGC6960, part of the Veil Nebula complex, also known as the Witch's Broom Nebula. To give you an idea of the light pollution  I deal with for my urban images, scroll down the page to a picture of my gear while I was capturing this image. The view is a 30 second exposure at f/5.6 with an ISO setting of 400 looking west over my scope.

According to Wikipedia - The Veil Nebula is a cloud of heated and ionized gas and dust in the constellation Cygnus.

It constitutes the visible portions of the Cygnus Loop, a supernova remnant, many portions of which have acquired their own individual names and catalogue identifiers. The source supernova was a star 20 times more massive than the Sun which exploded between 10,000 and 20,000 years ago. At the time of explosion, the supernova would have appeared brighter than Venus in the sky, and visible in daytime. The remnants have since expanded to cover an area of the sky roughly 3 degrees in diameter (about 6 times the diameter, and 36 times the area, of the full Moon). While previous distance estimates have ranged from 1200 to 5800 light-years, a recent determination of 2400 light-years is based on direct astrometric measurements. (The distance estimates affect also the estimates of size and age.)

Processing This image was captured using Sequence Generator Pro, telescope control provided by Mosaic Engine and processed entirely in Images Plus.  Initially an arcsinh stretch was used to brighten the image. The image was cropped and split into star and DSO layers using the feature mask tool. The DSO layer was noise reduced using a frequency domain low pass applied with a mask to limit the amount of blurring applied to the nebula. The nebula image was further brightened and sharpened using the multiscale decomposition tool. The stars were reduced and a slight trail fixed then recombined with the noise reduced nebula image. Multiresolution sharpening used to slightly sharpen the image. Curves were used to set the contrast and the image was binned by two for web download.
