Fabulous pics! I suppose these were all taken with the 80 mm APO and one of the Starlight Express cameras? Could you tell us how many subs you took and how you processed them?
The images above had a varied a mount of 3-5 minute subs, usually I take around 3 hours of data, and I use Astro Pixel Processor to do most of the processing , with a few final tweaks in PS.
The camera used was a SXVR M25 one shot colour, and SXVR h18 for mono which is added for the detail..except for the M42 shots which was just OSC
Can’t wait until the weather cleares (should be sometime soon in the next decade or so) and start on my list of nebulas.
