Description

Description (Wikipedia)

WR 134 is a variable Wolf-Rayet star located around 6,000 light years away from Earth in the constellation of Cygnus, surrounded by a faint bubble nebula blown by the intense radiation and fast wind from the star. It is five times the radius of the sun, but due to a temperature over63,000 Kit is 400,000 times as luminous as the Sun.WR 134 was one of three stars in Cygnus observed in 1867 to have unusual spectra consisting of intense emission lines rather than the more normal continuum and absorption lines. These were the first members of the class of stars that came to be called Wolf-Rayet stars (WR stars) after Charles Wolf and Georges Rayet who discovered their unusual appearance. It is a member of the nitrogen sequence of WR stars, while the other two (WR 135 and WR 137) are both members of the carbon sequence that also have OB companions. WR 134 has a spectrum with NIII and NIV emission between two and five times stronger than NV, leading to the assignment of a WN6 spectral type. The spectrum also shows strong HeII emission and weaker lines of HeI and CIV.

Personal Note

Beautiful Blue and Red; I really like to bright colours of this object.  Also spectacular is the round structure of the bubble with all its details. The processing challenge was to retain as much of the blue full circle structure as possible against the red Hydrogen gass. I applied the Fornaxx method to balance the channels; with a satisfactory result.

Processing

DBE, Deconvolution, Denoising, Star removal, MaskedStretch, ArcsinhStretch, Fornaxx combination of starless images and stars images, curves for color saturation and contrast, sharpening.
I prepared a Luminance based on H channel and full picture, but it did not add more quality to the picture, so I did not use them in the end.
