TEC APO250VT Triplet APO f/8.8

TEC APO250VT F/8.8 – TEC’s most powerful telescope. 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.

Our 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.

• The 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.
• The objective is housed in an titanium cell, providing for excellent thermoregulation properties while remaining lightweight and strong.
• The 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.
• Further, 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.
• Each 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.
• The 2” locking metal collet is insensitive to temperature fluctuations and holds loads with high precision and concentricity.
• Includes precision adjustable Tube Rings.
• Able to accommodate a wide variety of eyepieces.
• Recommended to be paired with a high capacity load mount and a stationary observation station.

In 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.
