![]() Used camera RAW filter to remove purple halos from stars ![]() Made the stars smaller by selecting highlights, then using the minimum filter (2 pixels)Ĭolour corrected the stars as best I could using the selective colour tool Load each image into its respective RGB channel in a new file I've never processed a NB image before so this was an exciting thing to learn on a rainy Saturday afternoon! It's taken about an hour to do while I figured out what on earth I was doing with the stars, still couldn't get it right but here's the process I followed using Photoshop:Ĭhange each individual image to an RGB 16bit imageĪdjust curves and levels, trying to ensure levels are similar across each image PhotometricColorCalibration for star colour and background neutralisation (narrowband mode)Īdjust contrast, colour and saturation of each layer to taste I opted to keep Gamma Cass big and bright as it's a key part of the composition for IC63 ![]() Multiple small stretches with HistogramTransformation then a MaskedStretchįor the stars, I used several Small stretches via HistogramTransformation to keep them tight with good colour. I like to try something different each time I process an IKO image and this time I used PixelMath "Dynamic narrowband combinations" to combine as SHO (based on the post at ) Thanks once again to FLO & IKO for this opportunity to work with quality data as the awful weather continues to dominate in my part of the world!īalance channels with HistogramTransformation SHO PROCESSED.tif Edited Februby Skipper Billy Masked the big bright star and reduced it as far as possible whilst still leaving it big and bright - which it is!įinal tweaks in curves and Histogram Transformation In Photoshop pasted the star layer onto the nebula layer at 95% 'lightness' then back to Pixinsight Processed stars with Multiscale median transform to reduce the size slightlyĪdjusted star colour in Curves transformationĪdjusted star brightness in Histogram transformation. TGV Denoise very gently - there wasn't much noise. ![]() Inverted the image and hit it with SCNR to remove Magenta Starnet++ to remove stars - from here on the processes are mostly to the nebula sans starsīoosted Reds and Yellows in Curves transformation Stretched individual channels to non-linearĬhanel combination using SHO (Hubble pallet) Some very minor masked selective colour adjustment to the orange and blueĪ selective high-pass on the "head and arms" of the ghost and a few other areas to bring out some structure.ĮDIT -Rev 2 placed after Carbonis actions to bring some colour back to the stars. LHE (very gentle) on HaĬombined in SHO-AIP script - several different blends until I got what I was looking for but essentially HSO with some of the Sii in red and some of the Ha in blue (I think!) with Ha as a luminance. Stretched all three gently using HT - further stretches with Star masks and range masks to focus on the nebula and keep y Cas in check. Lovely data like this makes processing so much easier and I really did not have to do that much to itĭecon and a gentle denoise (MLT) on the Ha I did this with much masking and stretching in PI I wanted to emphasise the ghost and his tail and minimise y-Cas. Processed In PixInsight with some finishing touches in PS.ĭone as HSO as I'm not really comfortable with the SHO pallet yet.
