Excellent image, almost starless. What's your secret to get such small stars?

Thank you.
I work mostly with mask, and pixinsight morphological transformation. Start carefully and repeat the procedure repeatedly

As above - very impressed by the star control- a difficult area for stars as I have imaged it with an 8 ich RCT - Tony.

Thats an image you could sit back and just let the imagination flow for hours, i like it a lot.

Pixinsight Morp.. For me when working with MT. in Pixinsight it always leaves trails of the removed stars even at "size 3", so I can only reduce the stars
max in 1 step. I guess I must be doing it all wrong when I see this pic. How do you do proceed when using MT in Pix, and do you use another software to smooth
out the leftovers of the stars?

That's a great image, so smooth. Your noise reduction skills are excellent, wish I could get my images to look that smooth.

Cheers, Ian

Hi, and thanks for the fine feedback.
I'm editing all my images visually, and there are a lot of back and forth with different software. I used MT several times in the process, but I make new mask as the stars grow smaller and smaller. I use some PS, and Capture nx2 and most PI to software. I often sit for many hours, and when the result is finished, I do not always remember the order in the process. But I'm saving many versions all the time

In this picture, I mean and have made a starless version of HA, which I'm imported as a Lum file also in the end

Ok. Thx Ola, tricky it is. I had not tested new mask on every MT done, I have tested several masks though when using MT, but not after each shrinking. Did some tests today actually and that image didn't like star shrink at all
I guess it is as usuall, if you fail, try try again.
