Description
APM Doublet SD APO 140 f/7 FPL53 OTA
The new APM 140mm f/980mm Doublet is a mold breaker with high quality.
APM has painstakingly engineered an optical and tube solution to bring you APM quality at an unheard of price. The new 140 mm SD Apo features a doublet lens cell using SD glass FPL53 to maximize performance. Their 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 532 nm (green) wavelength before shipping.
With 980 mm focal length, the 140 mm 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 APM believes they have created an apochromatic refractor of incomparable performance and value in its category.
