It is considered an observation class instrument. Weighing in at 50kg, the APO250VT F\/8.8 can be transported to various observing stations, however TEC highly recommends that a permanent observing station be made for this telescope. It requires a large mount and specialized accessories; however, it will provide some of the best observing available to the consumer.\u003c\/p\u003e\n\u003cp\u003eOur largest refractor, the APO250VT F\/8.8 allows the observer to immerse themselves in the beauty of space. This observatory class instrument provides the best visual experience that TEC has to offer.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eThe APO250VT F\/8.8 features an air-spaced apochromatic-triplet objective with a Fluorite (CaF2) middle element, resulting in color correction that is optimized for visual use and imaging. This air-spaced triplet design in combination with multi-layer coatings on all surfaces of the objective ensure maximal light transmission.\u003c\/li\u003e\n\u003cli\u003eThe objective is housed in an titanium cell, providing for excellent thermoregulation properties while remaining lightweight and strong.\u003c\/li\u003e\n\u003cli\u003eThe optical assembly sits in a lightweight aluminum tube that utilizes anti-reflective coating and sharp-edged baffles throughout the interior and forget about collimation – after the scope leaves TEC, no adjustment is required.\u003c\/li\u003e\n\u003cli\u003eFurther, the crisp all white assembly projects the elegant, handcrafted quality that TEC is known for. Expect deep contrast and rich, natural color out of this compact and timeless design.\u003c\/li\u003e\n\u003cli\u003eEach APO250VT F\/8.8 comes equipped with a Starlight Instruments FTF#3545 Feather Touch Focuser that was designed in collaboration with TEC. This is Starlight Instruments’ largest rotating focuser with coarse and fine focusing 9:1 Planetary Reduction Assembly.\u003c\/li\u003e\n\u003cli\u003eThe 2” locking metal collet is insensitive to temperature fluctuations and holds loads with high precision and concentricity.\u003c\/li\u003e\n\u003cli\u003eIncludes precision adjustable Tube Rings.\u003c\/li\u003e\n\u003cli\u003eAble to accommodate a wide variety of eyepieces.\u003c\/li\u003e\n\u003cli\u003eRecommended to be paired with a high capacity load mount and a stationary observation station.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eIn classic refractor fashion, the TEC APO250VT F\/8.8 is a no compromise, no frills design that lets the wonders of nature speak for themselves.
