Ivo - Thank you for implementing the circle and drag function

Post by RICH-DSO »

Ivo, Thank you for implementing the circle and drag function. I use it to remove and fix Oxygen III filter halos!

Halos like in this image...

Thank you so much!

:thumbsup:

3- make a smaller circle within the green circle for the white part of the star. The mask will be erased over the star
4- Open the color module, select keep mask, tune down the blue and possibly red until you have a good mix of background color.

Richard, that is a really nice image! :thumbsup: May I ask what scope/camera/filters you used and process in ST to achieve the beautiful color and detail?

That's a great use and example on that image, thanks for sharing.
I just used the new mask and removed the star centre and used Heal as the star field was quite dense around the problem star and that worked great (new darker than old off). I can see me using this new mask when dealing with CA I have with my lenses.

Ivo that is a super new tool in Mask, thank you.
