30/35mm Back FocuserThe focuser (Stroke 30/35mm) helps you quickly lock the stars you want to see. The focuser simply moves the attached device inwards or outwards while maintaining its orientation, which means your field of potential guide stars will not rotate as focus is adjusted, further increasing ease of use.10mm Helical FocuserAfter focusing, you can see details of the image clearer and brighter. The focusing accuracy is up to 0.1 mm. The 10 mm focusing stroke will meet your needs for viewing guides.M42*0.75 & 125inchThe MultiUse Guide Scope features male T-threads on the focuser collar for secure threaded attachment of guide cameras equipped with female T-threads.And the versatile Guide Scope can double as a straight-through finder scope with an optional 1.25" eyepiece installed. For example, insert a 20 mm eyepiece to create a 9.5x50 finder scope, or insert one Illuminated Centering Eyepieces for use as a finder with illuminated crosshairs for easy aiming. Fully Multi-coatedFully Multi-coated Glass means multiple coatings on all lens surfaces and all air-to-glass surfaces are anti-reflective multi-layer coated. And FMC lens has greater advantages in increasing the light transmission, delivering bright, clears and crisps images even in low-light conditions.Meticulous DesignA compression ring fitting keeps any inserted autoguider cameras or astronomy accessories free of pesky scratches. CNC machined aluminum alloy body with laser engraving letters has a long performance life.Metal Hoop with DovetailThe Multi-Use Guide Scope features a machined, knurled metal hoop to make fine focus adjustments nice and easy, while a thumbscrew lets you lock-down the focuser in-place once to complete adjustments.
