Description

The Wizard Nebula was the first target I ever tried with my mono camera and was hooked. I did such a poor job in hindsight, I want to try again with better methods and processing. I still may go back and add RGB stars at some point, but I think that this is a reasonably decent rendering. I applied three round of star reduction. There are so many stars in the field that even this was not enough. The field is just full of stars.

Comments and Critique is always welcome. Clear Skies.

NGC 7380 (also known as the Wizard Nebula) is an open cluster discovered by Caroline Herschel in 1787. William Herschel included his sister's discovery in his catalog, and labelled it H VIII.77. It is also known as 142 in the 1959 Sharpless catalog (Sh2-142). This reasonably large nebula is located in Cepheus. It is extremely difficult to observe visually, usually requiring very dark skies and an O-III filter.

Located 7200 light years away, the Wizard nebula, surrounds developing open star cluster NGC 7380. Visually, the interplay of stars, gas, and dust has created a shape that appears to some like a fictional medieval sorcerer. The active star forming region spans about 100 light years, making it appear larger than the angular extent of the Moon. The Wizard Nebula can be located with a small telescope toward the constellation of the King of Aethiopia (Cepheus). Although the nebula may last only a few million years, some of the stars being formed may outlive our Sun.

The lastest image is a full reprocessing of this old data. Data is data and my old techniques just did not do it justice. The main improvements were in noise reduction - Mure denoise and Noise Xterminator. These are major new tools that I did not have before. New stretching methods like ArcSinHStretch and GeneralizedHyperbolicStretch were not available then. I also am much better a techniques like LocalHistogramEnhancement. I also am starting to use LargeScaleEnhancement and LocalFuzzyHyperbolization.
