I imaged the entire Veil Nebula over the summer but revisited the Eastern Veil, specifically, with my Stellarvue SV102A to try and get a good image of the "Joker Face" before it was gone for the season.  I only ended up with about 4.5 hours of good exposures over two nights in late October.  Guiding wasn't good due to position in the sky and poor overall seeing.  Guiding for me gets much worse once I transit, as my neighbors to that side normally leave their porch lights on and seeing isn't as good for the guide cam.  I had to limit exposures to 180" to keep the stars sharp with a small patch of 300" subs.  I was imaging at the full 714mm, so didn't have much leeway for the guiding seesaw that happens for me with poor seeing.  I used an Optolong L-Enhance with a Risingcam IMX571 and Orion flattener.   

I wasn't really sure what I was going for when I began post-processing.  I've been playing around with dynamic expressions in PixelMath, as outlined in the Coldest Nights webpage, and trying different expressions applied to the strengths of the Ha and Oiii in the R, B, and G channels.  I opted to build a synthetic green, represented as a formulaic expression of both channels.  My Ha and Oiii were extracted using APP and both had DBE applied in PI.  I created a dummy sacrifice clone, to oversaturate colors to use for better color mask stretching and did much of the heavy stretching with color masks and GHS.  I normally blur my masks but did not do any mask blurring except with the yellow mask.  I wanted to retain a lot of the sharpness of the "shockwaves" and I've noticed blurring my color masks often introduces a soft, dreamy feel that wouldn't have worked well here.   Another departure for me, was removing the stars prior to stretching.  As a matter of fact, I didn't even use the stars from the HGO combination, but rather pulled the starts from the linear stack of L-Enhance data that was stacked with the normal Airy Disk algorithm in APP.  I then color calibrated this image with SPCC using the narrowband settings for the LEnhance.  I then registered this image to my main image and pulled the stars using Star Xterminator while still in linear phase.  I then slightly stretched these stars with Histogram Transformation until they got to a size I liked and added back in.  I'll normally go in and do some additional manipulating or sharpening, but opted not to this time.  I then did some denoising with Noise Xterminator.  There was some things I wish I would've done differently, and started to can the whole thing and start over.  But, I'm trying to go more with my gut rather than a set pattern of processing and once I'm finished with that flow and where it takes me, I close the book and move on to the next target.
