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 generous focal length of 980mm, the 140mm SD Apo is a real all-rounder. From observing close binary 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 3.7" 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 9.8kg is quite lightweight and can be used on compact mounts.
In this package we have included the 0.75x M63 APM Riccardi reducer / flattener for a focal ratio of f/5.25 at an image circle of 42mm. All needed adapters are included too.
The modern APM apochromatic SD refractor 140/980mm - Excellent performance at an incredibly attractive price!
