The APM 180mm F/7 Apo is an apochromatic triplet refractor with optics from APM's SuperED FCD100 Apo series. The air-spaced triplet lens cell provides exceptional correction. The use of two elements of FCD100 glass results in excellent control of chromatic aberration.

The APM 180mm Apo has a native focal length of 1260mm and a focal ratio of f/7, making it a powerful instrument for observation and photography of smaller objects, as well as solar and planetary work. The extended backfocus of 250mm from the 2" adapter allows the use of binoviewers with a 2" zenith mirror and without the need for a glass path corrector.

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 180mm refractor includes a test certificate.

The oversized 4.2" ZTA rack and pinion focuser is smooth and accurate with 1:10 fine focusing and integrated 360° rotator. It is designed to carry heavy imaging loads with ease. 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 optional 4" 0.8x reducer, the telescope is transformed into a highly corrected f/5.6 astrograph with a large full frame corrected image circle
