We had some delightfully clear skies during the recent September new moon, and I could imagine three nights in a row. I got three sessions of 30 300-second frames each night in narrow-band S-II, H-alpha, and O-III from here in Salado to create this image of NGC 6888, The Crescent Nebula, and the surrounding dark nebulae in LBN 205. I used my trusty Askar V in its 60mm aperture with its 0.7 reducer, creating a 270mm focal length using my other usual equipment. I processed the Hubble Palette image in PixInsight with final color touchup and flattening in Adobe Lightroom Classic, which has an amazing distortion removal tool that literally took all the lens curvature out of the image (as well as the others I have done this year).
There is a notable feature here worth noticing. As many of you know, NGC 6888 results from a repeatedly exploding Wolf-Rayet star (WR 136), emitting successive shock waves composed primarily of Oxygen. Its distinctive shape results from those shock waves being blown back, in this image from the upper left, by a strong galactic wind. Just to the upper left of the Crescent, you can see the waves formed in the dark nebula by that wind. Behind the Crescent can be seen a faintly fluorescing Oxygen whisp blown off the back of the Crescent by that same wind. I am quite happy that WR 136 and that powerful galactic wind are 5,000 light-years from us!
