I was in a local newsagent today and came across apublication from "Sky at Night" - Collectors Edition, titled "A Complete Guide to Astro Photography".
A quick browse through showed it had a lot of useful information on both equipment and photographing stars, planets (incl sun and moon) and DSOs. also a good section on processing images with readily available software.
At $14.95 I thought it was probably good value.
