Just to help a bit people that want to enable in the script list.
Edit it (with a text editor) and add at the top something like the below :
#feature-id Utilities > HaRGBCombination
#feature-info Script to combine Ha with RGB \
by Silvercup \
see http://pixinsight.com/forum/index.php?topic=3446.0
#feature-icon HaRGBCombination.xpm
save the script and then add it from Scripts -> Feature Scripts
Or, load it in the script editor and run it with F9
BTW, I did not had any crash issues so far and I have used it 10-15 times on old and new images, both under W7 64b and Linux 32bit.
1-2 small requests (Silvercup ? ) :
If you stop it abnormally it leaves residual views hanging around (Ha, R,G,B etc).
It assumes that there are no views already named Ha, R,G,B , which produces problems if there are.
It will be good (not confusing for the user) if the lists of views inside the script are excluding the above temporary views (the ones that the script is producing, ie R,G,B etc).
I would also like to have a way to preview HaEmmision, but since the script is modal and the view hidden.....
( Silvercup , did I mentioned how glad I am for this script?
