The TEC APO250VT F/8.8 is the largest refractor that TEC offers.  Considered an observatory class instrument, a permanent mounting solution is recommended for this telescope.  The views through this instrument are unmatched.  If you are looking for the very best in apochromatic refractors, look no further than Telescope Engineering Company.

Telescope Engineering Company (TEC) began in 1994 as a distributor/subcontractor of optics and optical materials. Initially, their primary products were zero-expansion Sitall blanks from LZOS, large mirrors and optical systems from LOMO, and optics for Maksutov telescopes made in Kiev, Ukraine.

In the late 90's, TEC decided to start its own production line of optics and telescopes. TEC began by producing a line of Maksutov telescopes ranging from 6" to 10" diameter and continued to work on special optics for professional observatories. At the turn of the century, TEC began working on a new product: apochromatic refractors. In 2002 they started regular production of smaller refractors, beginning with the APO140 F7 ED. Later on, TEC added larger models including the APO160, APO180 and APO200. Apochromatic refractors make up the majority of TEC's ongoing present and near future production.

The TEC APO250VT is a world-class instrument.  TEC telescopes are known for their precision machining and impeccable optics, and the APO250VT is no different.  If you have a dark-sky observatory, this telescope is what you want to have under the dome.
