Ha data was also captured over the California Nebula through a GT71QHY600 combo. Processed in Pixinsight and Photoshop using PIs Normalise Scale Gradient, Mosaic by Co-ordinates and Photometric Merge Mosaic to align and merge the panels, Stretched initially in PI using ArcSinh, GHS and HT, then stars removed with Russ Croman's Star Exterminator, further stretching of Starless image in Pi, then colour enhancement, Ha and Lum blending in Photoshop before replacing the stars in Photoshop using Screen mode.
