Some Sites and Books I've Found to be Helpful in My Astrophotography Pursuits
Backyard Astronomy Basics, Thanks Liam Brown for recommending this site and best of luck in your future scientific exploration! This is a great resource for the beginning astronomer.
The New CCD Astronomy, Ron Wodaski - The New CCD Astronomy is a book considered to be the bible of CCD astrophotography by many including me. This is a great book for learning the intricacies of CCD astrophotography.
The Handbook of Astronomical Image Processing, Richard Berry and James Burnell - This book includes AIP4Win a very capable post processing software and delves deeply into the mathematics behind image processing and acquisition. In my opinion, a must read to become truly proficient in the art of post processing.
A Practical Guide to CCD Astronomy, Patrick Martinez and Alain Klotz - Though a bit dated another fine book on the mathematics behind image processing.
Introduction to Digital Astrophotography, Robert Reeves - I picked up this book too late to be of great use to me but it's a fine book for the beginner that wishes to begin defining his goals and equipment requirements.
Mike Weasner's LXD55 Site - Mike's site is loaded with information on getting the most out of the LXD55 mount as well as many other scopes and mounts. Take note especially of the LXD55 Tips and Tricks on this page if you have a mount similar to the LXD55.
