• For those nights when you don't plan to capture astrophotos exposures, this versatile Guide Scope can double as a straight-through finder scope with an optional 1.25" eyepiece installed;
• The focuser boasts 8 mm of precise helical focus travel;plus telescoping drawtube housing provides up to 35mm 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 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.

Note: The SV106 can connect directly to an eyepiece (8mm or longer) for imaging, resulting in an inverted image. This setup enables deep-sky observation without a fixed reference. However, adding a zenith mirror increases the weight of the star guide and will not achieve focus.
