We also offer the 152mm optics in the CNC-LW II version. For special visual work (e.g. sun, projection) a modification of the back focus is desired, which we can easily arrange. The standard back focus is 220mm (variable according to customer adaptation and focuser used).
The top-class FeatherTouch™ 3.5" from Star Light Instruments is again used as the focuser. The tube is made of aluminum as standard. With our optimization, the weight sinks to just over 13kg, which is considerable for such a look and back-friendly.
The classic 6" aprture (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 delivery times of several years nor difficult to use optical designs that have to cool off for half a night.
The 6 "incher" is a great scope, both visually and photographically, which 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 aperture offers 2.5x more area than a 4" telescope and around 50% more area than a 5-inch telescope. Separate the closest double stars with colored components, touch into globular clusters and observe the finest planetary details. Photographically you dive deeper into groups of galaxies, high-contrast photography (e.g. with narrowband filters). Obeserving larger objects using a reducer are a pleasure.
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.
