![]() ![]() Label the result as luminance mask and invert mask on starless image.ĩ. Clip point varies on how cleanly the background/nebula split is.Ĩ. Clip luminance until ~50% of pixels are clipped. Curves transformation for another color saturation boost.ħ. Bring shadows back in and stretch more, maintaining 20% peak position without clipping.ĥ. ![]() Stretch until histogram peak is ~20% over from left.ģ. Tried GHS, but I'm getting error messages when I tried running it.Ģ. #Pixinsight 1.8 download seriesSeries of histogram stretches, though not mimicking the auto-stretch. I save this intermediate step in case I need to go back to it at a later time.ġ. Stitch it back together in PixelMath, GLOW+STARS becomes "PS1" for "Pre-Stretch Image 1", saved as TIF. ![]() Clone stamp in case there are dust motes flats didn't take care of.ġ0. On starless image (labeled "GLOW", for the object)ĩ. Literally grab the 50% point and drag it ~10% to 20% towards the lower-right corner. Curves transformation in RGB/K to reduce star size. Curves transformation to boost star saturationĨ. The 90% / 15% default seems a bit too "polished" or "wax"-looking to my eyes)ħ. NoiseXterminator (80% Denoise / 15% Detail. Photometric color calibration (NOTE-if the image is OSC Narrowband, I'll do photometric color calibration assuming this)ĥ. ABE/DBE, depending on the gradients involved.Ĥ. Dynamic crop for stacking artifacts/margins.ģ. Screen Transfer Function / autostretch.Ģ. I've just seen the improvement in the images using the following method, but am wondering if I can still improve upon it.***ġ. I'll post some of these in the next few days. ***NOTE-I haven't posted any photos with this method yet, but I have reprocessed several images using this method. Once it's in PixInsight, here's what I do. Why not use PixInsight? Because DSS is just too easy and learning everything in PXI is 10X harder than it needs to be. Personally, I find VisibleDark's the easiest to follow and understand, but to each their own.īasically, I'm wondering if you were taking OSC images (I have ZERO desire for mono imaging), how would you judge the following workflow?įor stacking, I just use Deep Sky Stacker and take the unmodified Autosave.TIF file straight into PixInsight. I mean, I've picked up at least a few things along the way. Finding the time to sit down to watch all 653,242 PixInsight YouTube tutorials (each spanning a length of geological time) is admittedly a hurdle. As time has gone by, I've gotten better at processing, but there's always room for improvement. I'm currently using modded Nikon DSLRs (D5300 and D5500) but just recently picked up an ASI 533MC-Pro. I've had PixInsight for about 2-1/2 years and got it shortly after taking up astroimaging. ![]()
