Processing

DSLRFocus was used for focussing. All separate frames were calibrated, aligned and stacked in ImagesPlus 2.8. "Dynamic Background Extraction" (DBE) was done in PixInsight. Photoshop CS2 was used for further processing - curves adjustment, levels adjustment, etc. The image was calibrated using 45 darks, 40 flats and 30 bias frames.
Above image is a "Pseudo" LRGB image. An artificial "L" component was added to the RGB image.
