Thank you Malcolm for the kind words, this is my first attempt to wrestle dark nebulae so I guess I am bound to do some wrong steps. I used UHS as Moon even though quite thin was positioned wey close to Corona to my liking but you're right in the hindsight I should try either none or just a UV filter to keep stars at bay. I love my ASI533 dearly but I fight star size all the time. I probably need to do some calibrating session where I take a range of times from shortest to longest and try to make some sense out of it. So far I am not touching gain and having it at 100 all the time so maybe that will be the next step too to try different settings for it too.
Fortunately this hobby is not a sprint and stars won't go anywhere so I will try again and again.
