The Zagorsk Optical and Mechanical Plant made not only an analogue of the Alkor telescope, but also an analogue of the TAL-1 Mizar telescope. It was called Kronos ZT-115. It was produced in the mid 90s of the twentieth century. According to undocumented information, Kronos telescopes were produced for only a year and a half. The telescope is very rare, for several years that I have been collecting the collection, I met it for the first time and I could not help but buy it. ))) Kronos ZT-65 appears on sale more often, about once every 1-1.5 years.
This is a Newtonian reflector with a mirror diameter of 115 mm and a focal length of 800 mm (possibly 802 mm, there is no exact information), F / 7. The secondary mirror of the telescope has a small axis size of 30mm, it is the same as that of the Kronos ZT-65. The telescope was mounted on a German-type equatorial mount equipped with both axle brakes and fine-motion screws. The telescope was packed in a huge and very heavy box that completely occupied the trunk of a Honda CRV car. The box was made from boards, not plywood. The telescope itself is also quite heavy - 26 kilograms. The wall of his pipe has a thickness of 8mm (!!!). The telescope tube has a finder with a break in the optical axis, 50 mm in diameter and 10x magnification.
According to the information that I was able to find, the telescope made it possible to obtain three magnifications: 58x, 100x and 179x. This is well achieved with one eyepiece and two Barlow lenses, as is done with the Kronos ZT-65. But the problem is that there are two eyepieces, completely identical in appearance (the same as those of Kronos ZT-65), but they are marked with different magnifications. The reason for this is not clear to me, there is no instruction from the telescope. The eyepieces are marked with one serial number, that is, they are all from this telescope.
Barlow lenses have the same small optical diameter as the Kronos ZT-65. It is noteworthy that the Barlow 100x lens has some kind of spacer in the form of a brass ring. She is unpainted. Why this was done is not clear. Perhaps during the design they made a mistake with the focal length and it turned out after production. The eyepieces of the eyepieces seem to be made of carbolite, while those of the Kronos ZT-65 were made of rubber. One eyecup, unfortunately, was broken.
