Description

While I would've loved to acquire some more narrowband data and some SII would enhance the image, I had a quick two nights before I sent off the camera for some repair. Given the data, I think this turned out well. I was very pleased with the NBRGBCombination script in Pixinsight, which I used to add Ha, OII, and (OIII + 15% Ha) to the R,G,B channels of the color calibrated image. I also formed a synthetic L by extracting the L of the calibrated RGB image and integrating it with Ha and OIII with noise weighting and no pixel rejection. This allowed me to deconvolute and get some additional detail out of the planetary nebular region. The rest is color and contrast enhancement to suit my taste. Hope you enjoy.
