TerryMcK Posted January 7, 2021 Share Posted January 7, 2021 I started this on Christmas Eve 2020 with my OSC camera and got around 87 decent subs of 6 minute duration. The job ran into Christmas day and I did some rough processing on the results but decided I needed some Ha with the mono camera to add to the RGB.Over the evening of January 6th to the morning of January 7th 2021 I got 60 Ha subs of 6 minutes duration each. On top of this I captured a further 24 subs of OIII before the clouds came in. I managed to close up the tent before the snow came and as I write this on January 7th the snow is coming down heavily.Technical details:Camera 1: ZWO ASI183 MC OSC, Filter: IDAS D2Camera 2: ZWO ASI183 MM Mono, Filters: 6nm Ha, 6nm OIIITelescope: William Optics ZS103Flattener/Reducer: William Optics x0.8Mount: Skywatcher HEQ5 ProGuider: William Optics 50mm with ASI120MMAcquisition dates: 24/12/2020-25/12/2020 OSC, 06/01/2021-07/01/2021 MonoIntegrated with AstroPixelProcessorProcessed with PixInsight and some work with Photoshop CC2021/Topaz Noise AI Click on the image for a bigger view (only a jpg here though). This will probably need some more work as the stars have developed panda eyes possibly due to star size reduction. 9 Quote Link to comment Share on other sites More sharing options...
TerryMcK Posted January 8, 2021 Author Share Posted January 8, 2021 This time I have done something slightly different. I started out with the RGB image which was acquired Christmas Eve and used that as the reference image. Then in PixInsight I used the Channel Extract script to extract just the blue channel. So all that nice red and green was removed.Next I used the Channel combination script to map the Ha image to red, OIII to green and the previously extracted blue layer into... blue.The process was then to crop to what I have here.Then after doing my usual workflow ofDBE, PCC, MLTNoise, Histogram transformation I arrived at the permanently stretched imageSome more HDRMultiscale transformation, TGVDenoise, Local Histogram Equalization and a final MLTSharpen.Finally I ran the DarkStructure enhance script and ended up with this. Again the jpg does not do it justice. 2 Quote Link to comment Share on other sites More sharing options...
