5mm more opening doesn't sound like much, but brings over 5% more light collecting surface. 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! This 7-inch device can be called the ultimate planetary device. Due to the shortened focal length, an aperture ratio of f / 5.25 can be achieved with our Riccardi reducer. Ideal for breathtaking astrophotos!
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.
This device is the first choice for serious observers! APM can deliver these very high quality triplet SuperED apochromats at relatively short notice and at very attractive prices! There are no delivery times lasting several years!
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.
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 can be tailored to your needs!
