The APM Apochromat 140mm f / 7 impresses with its high performance. We have succeeded in developing a telescope with high-quality optics and a solid tube at a previously unattainable price. The new 140mm - 980mm ED has doublet optics with SD FPL 53 glass. This new, innovative lens system leads to an optical performance that is far above the usual in this price category To guarantee the typical high quality of APM telescopes, every optic goes through an interferometric test at 532nm (green).
With its focal length of 980mm, the 140mm SD Apo is a real all-rounder. From observing close double stars with high contrast to detailed planetary observations, a new group of enthusiasts will be amazed by the APM quality of this scope. The well-known APM quality has proven itself in all areas. The large 2.5" focuser with rack and pinion and 1:10 gear remains stable even under high loads and is suitable for astrophotography with large sensors. In addition, this new apo with only 9 kg is quite lightweight and can be used on compact mounts. You may convert this scope into a fast astrograph by using our APM Riccardi 0.75x Reducer/Flattener (M82 model 2 for f/5.25).
The modern APM apochromatic SD refractor 140/980mm - Excellent performance at an incredibly attractive price!
