My bi-color edit of the Western Veil Nebula, a supernova remnant packed with H-alpha and Oiii. This has been a fun project, a very difficult one to capture in narrowband, maybe someday I'll add RGB stars to the scene to give it a bit more pop. I'm happy with the detail I was able to extract given the relatively short integration time, both H-alpha and Oiii managed quite a bit of signal. Shot with an ASI183mm-Pro and WO GT81 on a Sirius EQ-G mount, all subs are at Gain 178 and offset 11, 5 minutes per sub H-alpha was 72 total subs, Oiii was 63 total subs. Editing done in PixInsight, Photoshop, and Lightroom.
Here's a shot I've been sitting on for about...6 months. Stupid COVID, I had done pretty much all the subs for this, but got so busy with other stuff I completely forgot about finishing it, all I had to do was get new dark frames for calibration. So I put this edit together really quick yesterday, it's such an interesting feature with tons of dust and makes a very "artsy" SHO target. Shot with an ASI183mm Pro on a William Optics GT81 with a Sirius EQ-G mount, gain 178 offset 11. 90 x 5' subs for H-alpha 90 x 5' subs for Oiii 83 x 5' subs for Sii PixInsight Calibrated, registered, and stacked Each stack aligned to H-alpha DynamicBackgroundExtraction Stretched with EZ Processing Suite Combined channels with PixInsight Saved as BMP for editing in Photoshop In Photoshop I did mostly curves and saturation enhancements before uploading.
