The Etx And Lx90-acf Telescope Guide By Dr Lilian Hobbs
A really good introductory guide written specifically for the novice user, but also ideal for more experienced observers who have just bought an ETX or LX90 for the first time. It explains in easy-to-follow steps all the attributes and features of the scopes, its Autostar unit as well as suitable software and how to get the best from them. The 110-page guide is extensively illustrated with photographs and diagrams of the units, the Autostar and current astronomy software programs. This book is a must-have accessory to the ETX or LX90.
