These images were typically acquired using a Celestron 0.63x focal reducer with or without a diagonal. With the diagonal a non optimal F/4 focal ratio is achieved. With my typical straight through configuration with 108 mm gap between the focal reducer and the sensor yields ~F/6.3. Imager was ZWO ASI294MC-Pro @0C or 10C depending on ambient temperature.
Processing is with AutoStakkert for averaging subframes, Paintshop Pro X9 for image processing. In some cases the minimalist Fix app built into Window 10 Photo Gallery was used to tweak the image.
