A better balance between H alpha and O III render of the North America (NGC7000) and Penguin Nebulae (IC5070), high in the late-summer sky from Joppa, Texas, taken 2021-09-05 06:30 UT. These nebulae are rich in Hydrogen alpha and Oxygen III emissions. Oxygen III is naturally blueish green in color and Hydrogen alpha red. In this version I've used a machine learning based tool to separate foreground stars and nebulosity. This allows processing to be optimized for each.
This was processed with StarXTerminator from Russel Croman. I've also worked with StarNet++, but I think StarXTerminator does a better job.
WO RedCat 250/51mm telescope, Optolong L-eNhance NB Filter, ZWO ASI533 MC Pro cooled camera at -5C, SW AZ-EQ5 Pro mount, ZWO ASIAIR controller. About 2 hours of exposure with 42 3min images stacked . Processed in a HOO palate in PixInsight, StarXTerminator Topaz DeNoise AI, and Photoshop.
The image below is the live view stack automatically generated by the ZWO ASIAIR while acquiring data for this image. Compare it to the image above for an idea of the "value added" in post processing the data:
