Our 100 / 800mm system is the classic 4 "entry-level size, but here in excellent optical and mechanical quality! You can assume that the optics also meet the theoretical specifications in the sky. The

core of the device is the very high-quality 100mm optics, which we are aware of with a slightly longer focal ratio of f / 8.0. The focal length of 800mm is a very good compromise between visual use of high magnification and "space down" for great astrophotographic use with an extended field.

The optical design, a high-quality triplet with ED glass, has been tried and tested for a long time and has matured. The quality of the image, which by the way corresponds to a minimum standard of a Zeiss APQ, is underpinned by the solid cells, optimized for temperature compensation, as well as a high-quality multi-coating. The LZOS engineers have put all their knowledge into the calculation and manufacture of the frame and these optics, you can see that too! In order to substantiate this, an interferometric test report is enclosed with the optics.

The tube is made of aluminum, has a photo-visual aperture system and is very torsion-resistant.

The device comes in a beautiful complete package, which also optionally includes the high-quality APM ZTA 2.5 "focuser with 1:10 micro-reduction. The focuser can be rotated through 360 ° and is also ideal for astrophotography. The APM Fast-Lock is located on the eyepiece side. Adapter 2 "/ 1.25" included, which is also very valuable. M63 and M68 internal thread connections are also available. Everything is completed by a Vixen-compatible connection plate, high-quality CNC pipe clamps and standard finder shoe. End caps at the front and rear prevent the penetration of Dust and foreign bodies. Everything is safely stored in a sturdy transport case. The system is almost "ready to work". If you want, you can order finder or guide scopes of your choice and / or flattener / reducer for photographic work as an option.

A small, "poisonous" and powerful optic that shines with an excellent price-performance ratio!
