Product description
APM Doublet SD Apo 140 f/5,25 - 42mm image circle FPL53 optical Tube with 2.5" focuser

The new, compact all-rounder from APM with two-lens FPL 53 optics with Riccardi M63 Reducer

The new APM 140mm f/980mm Doublet is a mold breaker with high quality. We have painstakingly engineered an optical and tube solution to bring you APM quality at an unheard price. The new 140- SD Apo features a Doublet lens cell using SD glass FPL-53 to maximize performance. Our innovative combination of materials and design has resulted in optical performance far beyond the normal 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 140mm SD APO:
  •  Very high quality processed and of convincingly good optical quality
  •  Colorless optics with FLP53 glass
  •  Precise 2.5" focuser with 1:10 mirco reduction for heavy accessories
  •  With f / 7 ideal for visual
  •  With f/5,25 ideal for photographic purposes
  •  CNC tube rings
  •  Carry handle
  •  Very good value for money

With 980mm focal length, the 140-SD Apo 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.

Traditional APM quality has been applied in all areas. The new 2.5" 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.

With the new 140 mm SD Apo we believe we have created an Apochromatic Refractor of incomparable performance and value in its category.

With the Reducer you get an effective focal length of 735mm and an focal ratio of f/5,25.
