TS-Optics 152/900 RFT f/5.9 is a professional optical tube that can successfully function as a basic instrument for visual observations in a wide field of view, as well as an element of an astrophotography set.

The optics of this refractor consist of two lenses made of K9 and F4 glass. Thanks to the use of carefully selected materials and the highest precision of workmanship, this telescope, which is a classic achromat, is able to provide an image with a level of detail and contrast previously known only from apochromats, as evidenced by the fact that on the Japanese market the optical tube The TS-Optics 152/900 RFT f/5.9 offered under the name Nerius is classified as a semi-APO class telescope.

The instrument is equipped with a solid extractor with a diameter of 2.5", which allows you to connect accessories with an M68x1 thread, as well as glasses or angle attachments with a diameter of 1.25 and 2". .

An integral part of the TS-Optics 152/900 RFT f/5.9 telescope is a foldable deflector and solid mounting clamps made using CNC technology.
