The data for this LRGB image are from AstrophotoMarket (https://astrophotomarket.com/en/image-details/222/ldn-1622-hh-110): L (~19 hours exposure), RGB (~7 hours total), and Ha (~4 hours). The processing emphasis for this image was primarily focused on visualizing the HH objects, not LDN 1622. Gradients were removed from the RGB, Ha, and Luminance masters using MultiscaleGradientCorrection in PixInsight. The red channel was continuum subtracted from the Ha and then added to the RGB using PixelMath. The RGB stars were calibrated using SPCC after the addition of Ha. When removing the stars, it was noted that much of the HH objects of interest were removed by StarXterminator. This was avoided by using GAME masks. In addition to PI, some adjustments were also made in Photoshop.
