Hello Team!
I am after some advice for processing software. I have been using nebulosity up till now. I downloaded StarTools but it seems to run terrifically slowly on OS X. I do have access to a vista computer.
I am after something not as expensive as photoshop which I saw would cost nearly $1000. I have heard of GIMP- anyone any advice about that?
Also can you use astronomy specific add ons in GIMP like in photoshop?
I don't mind buying the licence but preferably not a grands worth!
TTFN
