Hi, my book – Demystifying Astronomy: A beginners guide to telescopes, eyepieces and accessories for visual astronomy – will be available from iTunes from June 1:
Demystifying Astronomy is an absolute beginner’s guide to choosing binoculars, telescopes, eyepieces and accessories for visual astronomy. Based on my own journey and extensive research in the subject, it provides everything you need to know to get started in this fascinating and hugely popular hobby. Discusses the differences between telescope types, what you should consider when making your choice, and what you can expect to see. Also explains focal length, collimation, and much technical terminology, as well as eyepieces, accessories, troubleshooting and maintenance.
