Hi All, getting into astrophoto instead of visual and need some critiques to get better at editing. I think I need way more time on all of them but winter has given me little time to get out to darker skies. Subs taken at a Bortle 4 site.
California Nebula – (125) 30 second subs taken on Celestron Origin mkii (6" RASA x 335mm with IMX674) on eq wedge and edited in pixinsight with SpectroPhotometricColorCalibration before using StarXTerminator. Processing nebula with NoiseXTerminator, BlurXTerminator a little bit, GeneralizedHyperbolicStretch. Processing stars with ArcsinhStretch. Pixelmath combining the image.
Specific comments would be greatly appreciated. I'm still trying to figure out my workflow and hoping to use that pixinsight trial period to its fullest.

It looks overstretched to me, try to strech a bit more conservatively, in steps, especially if you’re working with limited Data
Looking at the lower right, the darker areas appear a bit gnarly. In digital photography terms, looks over sharpened. Do not apply blurX and try GHS gently. See how it comes out. If you are still seeing those patterns pop out, go easy on noiseX. On the other hand try without the noiseX.
Save the images at each stage, that way do not have to do the whole thing again. Also, apply ABE after SPCC or before that.
