The focuser collar does not rotate as it moves, so an attached guide camera keeps its orientation while you focus. Tube rings and a dovetail rail are included, and the 1.25″ holder also accepts an eyepiece, so the SV106 works as a straight-through finder as well. It weighs 790 g.\u003c\/p\u003e\u003ch3\u003e\u003cstrong\u003eWho It's For\u003c\/strong\u003e\u003c\/h3\u003e\u003cp\u003eThis is a good match if you are autoguiding a deep-sky imaging telescope and want a short, fast guide scope that gathers plenty of guide stars, or if you want one scope that serves as both guider and finder.\u003c\/p\u003e\u003ch3\u003e\u003cstrong\u003eKey Features \u0026amp; Design\u003c\/strong\u003e\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e60 mm, 240 mm, f\/4:\u003c\/strong\u003e a wide, bright guide field for finding guide stars quickly.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNon-rotating helical focuser:\u003c\/strong\u003e 8 mm of fine travel without turning the camera.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTelescoping drawtube:\u003c\/strong\u003e 35 mm of coarse adjustment before the helical stage.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompression-ring holder:\u003c\/strong\u003e grips a 1.25″ camera or eyepiece without marring it.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFully multi-coated achromat:\u003c\/strong\u003e blackened lens edges for contrast.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAluminium tube:\u003c\/strong\u003e 66 mm tube diameter, 69 mm dew cap, 270 mm overall length.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRings and dovetail included:\u003c\/strong\u003e ready to mount on your imaging telescope.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0686\/0049\/6239\/files\/6378019382528839531909186.jpg?v=1791651294\" alt=\"SVBONY SV106 60mm guide scope specifications\" style=\"max-width:100%;height:auto;\"\u003e\u003c\/p\u003e\u003ch3\u003e\u003cstrong\u003eRecommended Uses\u003c\/strong\u003e\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eAutoguiding:\u003c\/strong\u003e paired with a guide camera such as the SVBONY SC715C or SV905C under PHD2.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinder scope:\u003c\/strong\u003e with a 1.25″ eyepiece for straight-through star hopping.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWide-field imaging:\u003c\/strong\u003e short focal length for very wide star fields with a small camera.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003e\u003cstrong\u003eCompatibility and Accessory Notes\u003c\/strong\u003e\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCamera connection:\u003c\/strong\u003e 1.25″ compression-ring holder, plus male T-threads on the focuser collar for guide cameras with female T-threads.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBack focal length:\u003c\/strong\u003e 220 mm.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting:\u003c\/strong\u003e included tube rings and dovetail rail.
