It has a 45° apparent field of view, 12mm of eye relief, weighs 70g, and Takahashi lists an overall body size of 33mm x 38mm (diameter x length) for this model.\u003c\/p\u003e\u003ch3\u003e\u003cstrong\u003eWho It's For\u003c\/strong\u003e\u003c\/h3\u003e\u003cp\u003eThis is a good match if you want a mid-to-high power eyepiece for planetary detail, lunar craters, and splitting closer double stars, with the sharp, low-distortion correction orthoscopic designs are known for.\u003c\/p\u003e\u003ch3\u003e\u003cstrong\u003eKey Features \u0026amp; Design\u003c\/strong\u003e\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOrthoscopic 4-element, 2-group design:\u003c\/strong\u003e low distortion, particularly at the center of the field.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e45° apparent field of view:\u003c\/strong\u003e steady framing at moderate-to-high power.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e12mm eye relief:\u003c\/strong\u003e workable for eyeglass wearers at this focal length.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e70g weight:\u003c\/strong\u003e light enough not to unbalance a small refractor's focuser.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003e\u003cstrong\u003eOptical \/ Mechanical Design\u003c\/strong\u003e\u003c\/h3\u003e\u003cp\u003eThe four-element, two-group orthoscopic layout holds sharpness and low distortion from the center outward, the trait that has kept orthoscopic designs in regular use for lunar and planetary observing even as wide-field alternatives have become more common. At 14mm, the OR-14mm sits in the middle of the Starbase orthoscopic range — short enough for real planetary detail, long enough to stay easy on the eye.\u003c\/p\u003e\u003ch3\u003e\u003cstrong\u003eRecommended Uses\u003c\/strong\u003e\u003c\/h3\u003e\u003cp\u003eOn a Takahashi FS-60CB (355mm, f\/5.9) the OR-14mm gives about 25x, useful for lunar overviews and brighter deep-sky targets. On a TSA-120 (900mm, f\/7.5) the same eyepiece yields roughly 64x — enough for real planetary and lunar detail on a night of average seeing. Divide any Takahashi tube's focal length by 14mm for the magnification on your own setup.\u003c\/p\u003e\u003ch3\u003e\u003cstrong\u003eCompatibility and Accessory Notes\u003c\/strong\u003e\u003c\/h3\u003e\u003cp\u003eTakahashi's product page for the OR-14mm gives a 33mm x 38mm overall body size rather than a separate barrel-diameter figure. The rest of the Starbase orthoscopic line uses the 1.25” (31.7mm) barrel standard that fits every current Takahashi focuser and diagonal.\u003c\/p\u003e\u003ch3\u003e\u003cstrong\u003eGood to Know Before You Order\u003c\/strong\u003e\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eNot parfocal with the rest of the range:\u003c\/strong\u003e expect to refocus when you swap eyepieces.\u003c\/p\u003e\u003ch3\u003e\u003cstrong\u003eFrequently Asked Questions\u003c\/strong\u003e\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eIs it difficult to set up?\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eNo — it threads directly into a standard 1.25” focuser or diagonal.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is it best used for?\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eMid-to-high power visual observing — planetary detail, lunar craters, and closer double stars.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow does it compare to the OR-9mm?\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eSame 4-element orthoscopic design; the OR-14mm's longer focal length gives lower magnification and a larger, more forgiving exit pupil on the same telescope.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat telescopes does it fit?\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eAny Takahashi refractor or reflector with a standard 1.25” focuser or diagonal.\u003c\/p\u003e\u003ch3\u003e\u003cstrong\u003eBottom Line\u003c\/strong\u003e\u003c\/h3\u003e\u003cp\u003eA 14mm orthoscopic eyepiece with a 45° field, 12mm eye relief, and a 70g weight — a sharp mid-power choice for planetary and lunar detail.
