The APM 140mm F/7 Apo is an apochromatic doublet refractor with optics from APM's SuperED FPL53 Apo series. The air-spaced doublet lens cell provides exceptional correction for observation and astrophotography.
The APM 140mm Apo has a native focal length of 980mm and a focal ratio of f/7, making it the ideal instrument for capturing a wide range of deep sky objects. The optics feature broadband multi-coatings on each surface for high contrast and transmission. All APM telescopes are tested at the factory with an interferometer to guarantee their performance.
The 2.5" ZTA rack and pinion focuser is smooth and accurate with 1:10 fine focusing and integrated 360° rotator. Equipment can be securely fastened by using the included APM Fast Lock 2" & 1.25" adapter.
The telescope comes standard with a Losmandy-style bar, CNC-machined rings, carrying handle and high quality APM-LZOS aluminium tube.
With the addition of the universal APM Riccardi 0.75x reducer, the telescope is transformed into a highly corrected astrograph with a large 40mm corrected image circle.
Note: The main photo is the version with the 3.7" ZTA focuser.
