Amateur Astronomers Project Guide to Astronomical Masks provides hundreds of Hartman/Schneider style objective focusing masks for various refractor, reflector, Newtonian and SCT telescopes. In addition to the predesigned templates, the book also includes step by step illustrated instructions, material lists and other "how to" advice allowing the entire family to join in on the fun of creating something new. Whether an arm chair astronomer or die hard observer, there is information for both to enjoy with chapters which discuss in detail the fine art of focusing including a micrometer focus control for astronomical imaging or masks for simple backyard star gazing. To complement these sections, they are supplemented with associated projects such as a DYI artificial star, SCT focus knob and many more. This book is a great companion for those cloudy nights, or sunny summer weekends as well as a great tool for getting the whole family involved in the love of the night sky with many daytime projects...
