Color Reiner 3 linsiger apochromatic refractor for visual observation and with our new optional 0.75x Riccardi Reducer / Flattener or the optional 2.5 "flattener TS also for astrophotography - even for large chips optimally equipped.
The lens is a 3-linsiger air gap-Apo, is used, the type of glass FPL-53, of course, fully multi-coated.
Qualitatively, the optics are better than diffraction limited. You can expect a good photo-visual, of general purpose Apo refractor. Venus can be seen even at 300-fold in focus without color aberration, the lens barrel (please do not center customer himself!) Mittles tension and compression screws fully adjustable and with lateral screws also fully centered.
When focuser is a first-class, 360 ° rotatable 3 "Pinion extract with 1:10 fine drive. The rotation gives you the option to rotate the photo accessories into the required position.
Large, fully corrected field through large 3 "extract and optional Reducer / flattener. (Connecting thread tube 114 mm x 1 mm)
The massive 3 "Pinion extract guarantees a very good illumination. Even large CCD cameras, such as the STL 11000, are / Flattenern fully illuminated with the optional reducers. The pipe clamps are on both sides flat with 5 threads 1/4 inch (photo thread), the two outer threads are held 60.2 mm hole size on Losmandy 62 mm hole size, the two inner thread on Astrophysics.
