Four 1.25″ eyepieces stay mounted at once and rotate into the light path, so changing magnification is a turn of the turret rather than an eyepiece swap in the dark. The 90° geometry means you observe at a comfortable angle throughout, and the whole assembly consumes only 81 mm of back focus — modest enough to work on most telescopes.\u003c\/p\u003e\u003cp\u003eA click stop locates each position positively, and an ocular indicator mark shows which eyepiece is in use. The nosepiece is a 2″ fitting for a secure hold in the focuser or diagonal.\u003c\/p\u003e\u003ch3\u003e\u003cstrong\u003eWho It's For\u003c\/strong\u003e\u003c\/h3\u003e\u003cp\u003eThis is a good match if you observe targets that reward working through several magnifications — planets, the Moon, doubles — and would rather not handle loose eyepieces at the telescope.\u003c\/p\u003e\u003ch3\u003e\u003cstrong\u003eKey Features \u0026amp; Design\u003c\/strong\u003e\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFour 1.25″ eyepieces mounted at once:\u003c\/strong\u003e magnification changes by rotating the turret.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e90° design:\u003c\/strong\u003e a comfortable viewing angle at every turret position.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClick stop positioning:\u003c\/strong\u003e each position locates positively rather than by feel.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOcular indicator mark:\u003c\/strong\u003e shows which eyepiece is in the light path.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e81 mm of back focus:\u003c\/strong\u003e compatible with most telescopes.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e2″ nosepiece:\u003c\/strong\u003e a secure fitting for the weight of four mounted eyepieces.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003e\u003cstrong\u003eRecommended Uses\u003c\/strong\u003e\u003c\/h3\u003e\u003cp\u003eVisual observing where magnification changes often — planetary and lunar sessions, double-star work, and public or group observing where handling loose eyepieces is awkward.\u003c\/p\u003e\u003ch3\u003e\u003cstrong\u003eCompatibility and Accessory Notes\u003c\/strong\u003e\u003c\/h3\u003e\u003cp\u003eTakes four 1.25″ eyepieces — a good match for Takahashi's LE and Abbe series, or any other high-quality eyepiece in that barrel size.
