Apochromatic telescope with excellent color correction and a flat field even in cameras with a full-format matrix. A good alternative to the famous Takahashi FS-60 astrographs or the Pentax 75 SDHF astrographs. A three-lens lens made of FPL-53 glass guarantees color correction in the focal plane of high quality, enabling visual observation at magnification up to 150 times, with only a pure chromatic aberration. The integrated equalizer, installed in the optimal location of the optical path, provides a flat field for cameras with matrices of up to 44 millimeters. The "baffles", or inner tube diaphragms - of appropriately sized sizes and the position inside the tube contribute to obtaining correct images. They do not cause vignetting when using cameras with large dies. The telescope is equipped with a 2 inch rack & pinion with an improved bearing system. In contrast to the Crayford extracts, it guarantees a smooth adjustment of the focus even under heavy loads (up to 3 kg). In addition, the extractor is equipped with a focusing knob with micro-regulation of 1:10. Accessories are fastened with a copper ring ( clamping ring ) and two counter-locking screws. The set includes a 1.25 inch adapter adapter and a standard foot for attaching the finder (finder available separately). Tuba has a retractable difler, which means that the telescope's length for transport is only 34 cm. The set also includes CNC clamps. Dovetail in the Vixen / SkyWatcher / Meade system - in option.
Characteristics
