Wolfie! I'm not that good, there are others here with dedicated astrophotography software that are far better at it than me.
I am limited to what I can do with this picture publisher 8 as it is not dedicated for astro-pics...but I have learnt to use it to the best of my ability.
Neatimage is free to get off the internet & I can recommend it for taking noise out of pictures.
But yes, I would be glad to reprocess your images! I now ask permission to have a go at your last image posted.
