NGC6888 in Ha
« on: 2014 November 03 02:18:22 »
Hi,

A image of the Cresent Nebula in Ha. The image is captured by use of Boren-Simon 8" f/3.6, Starlight Xpress H9 with a 6nm Ha filter.

Have made a lot of versions where the main challange has been to preserve the details in the outher parts of the nebula, easily burned out. Solved this by a "strong" MaskedStretched so that only reduction of saturation was necessary, mostly curves . One other, for me a not normal steps, was a bit sharpen by using deconvolution with starmask at non linear stage.
