APM - LZOS Telescope Apo Refractor Astrograph 115 f/5.25 - 42mm 3.5"ZTA

Our 115mm (4.5 ") system with a focal length of 805mm (f / 7.0) is just a tad heavier than the 105 Apo, but still perfectly transportable. Here, also the high class system from the APM SuperED Apo series is used, which is very harmoniously coordinated with regard to visual and photographic use.


10mm more aperture compared to 105mm lenses doesn't sound like much, but it already means an increased limit size and improved resolution, e.g. on the double star. The light collecting area is already approx. 30% larger than with a 100mm lens! The focal length of approx. 800mm has been chosen very universally, with our 0.75x Riccardi reducer a CCD-friendly focal length of approx. 600mm can be achieved.

The system comes with a large 3.5" FeatherTouch™ focuser, which is known for its excellent quality. The features: 360° rotatable and separately clampable, 1:10 micro reduction, adapter to 1.25" is included. The aperture is dimensioned largeenough that vignetting is excluded. The focuser tubeends with i reducing adapter 3" - 2" with clamping ring and an adapter 2" - 1¼" with brass clamping ring. With the included 80mm extension tube, you can vary the visual accessories very well.

With the dlivered Riccardi Reducer M63, the focal length is reduced to 604mm, whereby the aperture ratio is reduced from f/7.0 to f/5.25. The fully corrected image circle is 42mm.
