Chris, I'm still fudging my way around StarTools myself.
I've watched some tutorials and have visited the StarTools forum but it's still not easy to get my head around it.
Basically I just go with the default settings with most of the modules. I was starting to learn what the parameters were about but then had a break from imaging and misplaced my notes.
The colour module I find is confusing. From what I've read some other processing software will inaccurately alter the colour when stretching an image, ie the colour in the image is stretched along with the luminence.
StarTools keeps the original colours when stretching. An example I saw was M42. Very few images you see will show green around the centre of the nebula. According to the author of StarTools the centre should have a green tinge to it.
So do we buck the trend and show our images with 'unusual' colours or go with what is generally considered the 'normal' colours?
Anyway, in short I can't really give you any tips as I'm still very much a learner. I'm always open to advice if you have any for me
Regards
