ASTELE™ 150 (Astronomical Telescope)

ASTELE™ 150 EL

The ASTELE™ 150 is an excellent astronomical telescope for observing the heavens. 

Its optical design is Maksutov Cassegrain. 
Its diffraction limited optics are multi-coated and make it a great instrument for doing astrophotography as well, delivering pin-point images over a 35mm format.
If you're looking for a telescope that's easy to setup and has superb optics, the ASTELE™ 150 is that and more. Ideal for the professional or advanced amateur.
The ASTELE™ 150 uses U.S. standard 1.25" O.D.-sized eyepieces (hundreds are available).

The ASTELE™ 150 is available in three models

  • The ASTELE™ 150 OTA (Optical Tube Assembly).
  • The ASTELE™ 150 G (German Equatorial Mount)
  • The ASTELE™ 150 EL (with motorized base, shown)

The ASTELE™ 150 G (German Equatorial Mount) comes with slow-motion controls, setting circles, polar axis finder, accessory tray and fully adjustable aluminum tripod.
