These large optics are seldom found in the astronomical community, as the production is very high engineering. It is an apochromat with a classic f/8 ratio, with a 175mm aperture 1400mm focal length.
A 175mm aprture provides more than 3x as much area as a 100mm telescope and twice as much area as a 5-inch scope! The resolution of below than 0.7" is very interesting, it is also possible to separate very difficult double stars. This resolution gives you a breathtaking detail view of the moon and planets, especially binocular! The 7-inch refractor can be called the ultimate planetary device. No 7" Apo below a Strehl value of 0.96 leaves us, these are the same quality guidelines as with the Zeiss APQ!
With this telescope you can rely on exceptional performance data that will give you unforgettable hours! Due to the full, customer-optimized adaptation of the tube, e.g. Binocular attachments or larger solar observation equipment are no problem at all! Planets are an absolute pleasure, solar observation is possible on an extreme level! Of course, semi-professional work is also possible in photography! Many of these large refractors are installed at institutes and research institutes.
The classic 7 inch aperture is a size for serious observers! APM can deliver these very high-quality triplet SuperED apochromats at short notice and at very attractive prices! There are no delivery times lasting several years!
In addition to the large 3.5" FeatherTouch™ focuser, all the important reducing adapters are already integrated in order to conveniently connect both photographic and visual accessories. Tube rings are standard, as is the finder bracket.
