Hi Chris,
I gave a presentation at the Ice In Space Astro Camp (IISAC) at Lostock about 6 years ago on "Visual Astronomy and the Use of Filters".
I have attached a link to my Power Point Presentation and you might find some helpful information in there.
You can just download the PDF file linked on that page.
Technology and Brands have moved a little bit over the past 6 years but the basics haven't and won't ever change. At the end is a summary on a whole list of the Wratten number colour filters and what targets / features you might find them useful on. Obviously they work slightly differently for different people, but it's a good starting point for you.
Cheers,
John B
