Hi all,
Taking advantage of cooler and clearer winter nights I was able to collect about 23 hours in Ha, OIII and SII during the last week.
I have decided to again experiment with a Riccardi reducer, so the data is from a combination of f/6 and f/4.5 from the same 105mm refractor. I also decided against using any noise reduction on this image.
