Our top-class ZTA extract with 3.7 "serves as the focuser. The tube is made of aluminum as standard. With the composite tube (optional) the weight drops to just over 13kg, which is remarkable for such an optics and is easy on the back.
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 6 "opening (152mm) with a focal length of 1200mm is very popular and was launched by all well-known optics manufacturers worldwide. APM can deliver the very high-quality Triplet SuperED apochromats at short notice and at very attractive prices! There are neither multi-year delivery times nor fussy optic designs Have to cool down for half a night.
The 6 "-incher is both visually and photographically a great device that can be used universally. The focal ratio of f / 7.9 allows a relatively" slim "optical design with rapid cooling as well as excellent chromatic and spherical correction. The 152mm Openings offer 2.5x more area than a 4 "device and about 50% more area than a 5-inch device. Separate the tightest double stars with colored components, break them up into globular clusters and observe the finest details of planets a, high-contrast photography (e.g. with narrow band filters) or larger objects using a reducer are a pleasure.
In addition to the large 3.7 "focuser, all the important reducing adapters are already integrated in order to conveniently connect both photographic and visual accessories. Pipe clamps are standard, as is the viewfinder bracket.
A wonderful high-tech device that you can help design!
