Cleaning Up Your Masks!

2-Minute Tutorials

Jan 4, 2023

This video deals with Cleaning up, Editing, or customizing your mask to make them more useful.

This often takes the form of creating the mask with one set of tools and then using another to remove, add, or modify elements of the mask.

In this video, I am using DynamicPainBrush, a $5 premium utility by RBA-Tools, that I think is well worth the $5! I use it all of the time.

It can be purchased here: http://www.deepskycolors.com/RBATools/DynamicPaintbrush.html

UPDATE 1-5-23: I just learned that DynamicPaintBrush is only available for Windows. The authors had indicated that they would release a version on other platforms, but this has never happened.

Because of this, I will do another video using the CloneStamp tool to accomplish the same thing for those who cannot get this tool. You can also use the built-in CloneStamp tool using the "Paint Pot Method." I find this to be very inconvenient - which is why I use the DynamicPaintBrush.

Others I know write the mask to a Tiff file, open the mask up in Photoshop, make changes there, save the file, and then reload the modified mask back into Pixinsight. Again, I find the DynamicPaintBrush to be way more convenient!
