摘要

DOBSONIAN TELESCOPES are remarkably effective instruments in spite of their inherent simplicity. And yet, there are good ones and there are bad ones -it all comes down to how smooth and controllable the scope's motions are. It's been my experience that it's the smallest, most-lightweight Dobs that tend to perform the least satisfactorily. Such instruments can be finicky to balance, and they often move too easily for precise aiming. Luckily, there's a simple hardware-store fix: springs.
