A 175mm opening provides more than 3x as much area as a 100mm device and twice as much area as a 5-inch device! The resolution of less 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 device 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 device 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 facilities.
LZOS conducts its own glass research / development and also produces these glasses itself. This results in perfect control of every development stage. APM has been a partner for civil optics for decades and can actively participate in the development of optics, which contributes to the optimization and adaptation to the needs of professional and amateur astronomers.
The classic 7 “opening is a device 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, sleeves and the viewfinder holder are already integrated in order to conveniently connect both photographic and visual accessories. Multi-compatible pipe clamps are standard, a sturdy transport box is optionally available.
A wonderful high-tech device that you can help design!
