I have an opportunity to build two 12.5" iDK telescopes with ultra low expansion (ULE) optics. The primary mirror will be Zerodur and the secondary mirror will be quartz. ULE optics maintain a stable optical figure across a wide range of temperatures making your scope ready as soon as the skies get dark. Get yours while they last at an incredible price that is only $1000 above normal list price....$11,695.

- Ultra low expansion Zerodur and quartz optics figured and quality tested as a system to ensure excellent performance, enhanced aluminum coatings

- Fast F6.7 system designed and baffled to cover 16803 size chip, excellent field illumination (larger field of view, shorter integration times compared to F8 to F10 systems)

- 11" of back focus (from back plate to focal plane) to support almost any combination of imaging components

- CNC-machined, multipoint flotation mirror cell with stable, precise collimation adjustments

- Cooling fans included as standard with option to add heaters and AG Optical Systems Thermal Control System

- Outstanding coma free, astigmatism free, flat field performance over 65 mm image circle

- Broadband multi-coated, permanently aligned corrector element

- Rock solid, precise Optec TCF-S3i 3" digital focuser with temperature compensation feature

- CNC-machined components, stainless steel fasteners, dust cover included

- Optional truss shroud (which doubles as a dust cover) available

- Carbon fiber truss OTA for focus stability, carfully blackened interior to suppress stray light

- Optional .7x reducer coming soon converts scope into fast F4.7 system

- 100% Made In the USA backed by excellent, responsive customer service
