A powerful optical tube with a parabolic mirror with a diameter of 254 mm made of Pyrex - a great tool for highly advanced visual observations and astrophotography at the highest level. Great parameters of resolution and star range make it the perfect equipment for demanding observers. The catalog of observable objects includes: caps on Mars, Great Red Spot and Jupiter's moon transits, Saturn ring with Cassini and Encke break, all Messier objects and hundreds of galaxies, clusters and NGC / IC nebulae.
A complete tube with clamps, a 2 "/ 1.25" extractor and a very good 9x50 finder.
For visual observations, the HEQ-5 class is required, for astrophotography an EQ-6 class installation is required. • Optical construction: Newton telescope
