APM Refractor Telescope Doublet ED Apo 152 f/7.9 OTA with 3.7″ focuser

The new APM 152-1200 Doublet is a mold breaker in the 6″ Refractor category. We have painstakingly engineered an optical and tube solution to bring you APM quality at an unheard of price. The new 152-1200ED features a Doublet lens cell using ED glass equivalent to FPL-51 complimented by a Lanthanum coated element to maximize performance. Our innovative combination of materials and design has resulted in optical performance far beyond the norm for a telescope of this price. As with all APM telescopes consistency is assured and each telescope goes through an interferometrical test at the 532nm (green) wavelength before shipping.

The special feature of the 152 mm ED APO:

  •  Very high quality processed and of convincingly good optical quality
  •  Colorless optics with FLP51 glass
  •  Precise 3.7 “focuser with 1:10 mirco reduction for heavy accessories
  •  With f / 7 ideal for visual and photographic purposes
  •  CNC tube rings
  •  Carry handle
  •  Very good value for money

With a generous 1200mm focal length, the 152-1200 ED is an impressive all-rounder. From intricate double star observing to high contrast detailed planetary views, this new scope will introduce a whole new group of Astronomy enthusiasts to APM quality.

The new 152-1200ED is also supplied with extensive accessories. Inside the quality Aluminum transport case you will find not only a fantastic value telescope but also a newly designed 3,7″ focuser, CNC tube rings incorporating a carrying handle, 330mm Losmandy style dovetail and finder bracket.

Traditional APM quality has been applied in all areas. The new 3,7″ focuser is a Rack and Pinion type, with 1:10 focusing. It remains rigid under high loads making it suitable for imaging. The attention to detail extends to areas like the 2″ and 1.25″ eyepiece adapters. These use a new design of collar clamp, far superior to the common brass compression rings found on lesser designs. Also new is our 2″ APM  Fast Lock adapter now .

As an optional photo accessory for the ED Apo 152 f/1200 , we recommend our Riccardi Flattener APO Reducer 0.75xM82 (the focal length is reduced to 900mm at f / 5.9) or our Riccardi APO Flattener Model 2 for APO’s. (please look at our recommended products)

With the new 152-1200ED we believe we have created an Apochromatic Refractor of incomparable performance and value in its category.
