No worries Jethro
Firstly I am not by any stretch an imager, so there will be lots of people here on IIS that have more knowedge than I. That said I know enough t have a pretty good idea what will not work.
What sort of gear do you have? Eg dslr? Lenses? etc.
I can recommend this book
http://www.bintel.com.au/Accessories...oductview.aspx which is an intro to DSLR imaging and is a good intro to the general principles of astro imaging.
Should give you some ideas.
