From the reviews of the first edition: “Swanson includes thorough, model-specific descriptions of the all the telescope functions, care and maintenance, accessories, and numerous advanced topics. You’ll find advice on how to fine-tune your alignment so that a new target will fall within the eyepiece’s field of view every time you slew. I used to be pleased if that happened two or three times in a night. … I was surprised by the difference these small improvements made in the pleasure of my observing experience. … true advantage comes from its friendly approach and sound advice based on the personal experiences of the author and other avid NexStar users.” (Sky & Telescope, December, 2004)
