Description

The data is obtained from  Mr Vincent J Misti,  I have  process this data using Pixinsight, I had to convent from a Jpg to Tiff to be able to process it in Pixinsight. I decided to reduced the stars mass and revile the massive gas region behind, with the help of starnet and starmask followed by Morphological Transformation.
Overall Workflow:

Processing Phase       i.            DBE on each Filter     ii.            Color (RGB) Combination   iii.            Background neuration   iv.            Colour Calibration     v.            Denoise TGV and MLT – EZ SCRIPS   vi.            From STF to Histogram Transformationvii.            SNCR (80%) RGB Non-Linear Phase viii.            Star Mark – creation for denoises application or star reduction (EZ Script).                               i.            Will create a Starnet (keep it)                             ii.            Do a Clone Stamp to clear the artifice.                           iii.            Will create a Star Mask (keep it)   ix.            Star Reduction/Roundness Morphological Transformation (does a more reduction!)                     i.        Do a star mask                   ii.        Then a MT     x.            Star Net-Clone Stamp   xi.            Color Maskxii.            Color Curvesxiii.            Noise Reduction[b] [/b]Luminance Phare(if its form taken image , not extracted) xiv.            DBE – Luminance as per RGBxv.            Deconvolution -EZ Scrip (for sharpening)xvi.            Curves Transformation to bring out overall brightness-slightly                               i.            Lum De-noise (Mask) MLT-TGV – ACDNR)                             ii.            Lum Sharpening (might use it)                           iii.            Lum Dark Structure Enhance Scripts (might use it)xvii.            Linear Fit on RGB with Lum[b] [/b]LRGB Combination xviii.            LRGB combinationxix.            Before Enhancement, I did noise reduction MMT or ATWT xx.            Star Mask using Morphological Transformation to round the starsxxi.            Image Enhancement
 iv.            GAME mask   script to localize the three  objects. v.            Enhance Contract (Local Histogram Equitization) (IP4AP)xxii.            Final Color Adjustment                    vi.            Curves Transformation                    vii.            Color Saturation                    viii.            Star Color Adjustment
