Nice ones. I like the full disk, nice and sharp. Love the detailed shots too.

Two questions.... Is the dark feature bottom right in the Ha image 'real', or an artefact of some sort?

Am I right in thinking I can see Newton rings in the Ha? Anything you can do to reduce these? Btw I'm not an imager so am asking these purely out of interest and from a position of almost complete ignorance

The dark feature is some kind of dirt in my qhy5—LII. It was there in my white light close up as well, but I could correct it by adding a flat field shot.

Unfortunately,  I didn`t take flats to correct my h alpha images. It would have help reducing the newton rings too.
