The APM 152mm F/7.9 Apo is an apochromatic doublet refractor with optics from APM's SuperED FPL51 Apo series. The air-spaced doublet lens cell provides exceptional correction for observation and astrophotography. The use of one element of FPL51 glass combined with a second lens made from lanthanum glass results in excellent control of chromatic aberration.
The APM 152mm Apo has a native focal length of 1200mm and a focal ratio of f/7.9, making it the ideal instrument for capturing a small planetary nebulae and galaxies. 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 large 3.7" 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 M82 Riccardi 0.75x reducer, the telescope is transformed into a highly corrected astrograph with a large 52mm corrected image circle.
