What makes a telescope fall into the โgrab โnโ goโ category? Thatโs easy โ speed of setting up, ease of use, and above all, portability.
In Part I of this book, we survey the various types of equipment, including accessories and mounts, that are available, and what it is best for what kind of viewing.
Part II is about using your grab โnโ go telescope to visit a wealth and wide variety of objects. There are chapters on solar, lunar and planetary observing, as well as descriptions of many deep sky objects, including double and variable stars, planetary, emission and reflection nebulae, open and globular clusters and distant galaxies.
This ambitious text is dedicated to those who love to or โ because of their limited time โ must observe the sky at a momentโs notice, whether from the comfort of a backyard or while on business or vacation far from home. Everything you need to know is here. So get started!.
