Description
The Orion 60 mm Multi-Use Guide Scope with Helical Focuser features a built-in helical focuser that allows precise focus adjustments with zero flexure for rigid performance. Obtaining a clear, sharply focused view of potential guide stars is quick and easy with this sturdy scope. The fixed-orientation focuser mechanism will not rotate inserted autoguider cameras or eyepieces when focus adjustments are made. The helical focuser simply moves the attached device inwards or outwards while maintaining its orientation. This convenient feature means your field of potential guide stars will not rotate as focus is adjusted, further increasing ease of use.
The f/4, 240 mm focal length Orion 60 mm Multi-Use Guide Scope features a machined, knurled ring to make fine focus adjustments nice and easy, while a thumbscrew lets you lock-down the focuser in-place once adjustments are complete. The focuser boasts 10 mm of precise helical focus travel, plus a telescoping drawtube housing provides up to 35 mm of additional back-travel if needed for your particular autoguider device. No extension tubes necessary! A compression ring fitting keeps any inserted autoguider cameras or eyepieces free of pesky scratches. The Orion 60 mm Multi-Use Guide Scope with Helical Focuser also features male T-threads on the focuser collar for secure threaded attachment of guide cameras equipped with female T-threads.
