TS-Optics 6" f/5.9 Refractor with 2.5" R&P FocuserA great alternative to simple achromat refractors but also to very expensive ED and APO refractorsThe optics
One of the best lenses with a better color correction than a comparable achromat. For the lenses of the 2-element objective, K9 and F4 were used.
The lens is made very precisely, so that even at high magnifications the image hardly shows any color aberrations. The chromatic aberration, which is a blue border around bright stars or lunar craters, is barely visible.
Of course, both lenses have a broadband multi-coating on the surfaces. The lens is mounted on an adjustable and temperature compensated aluminum cell.
The 2.5" focuser of the Individual 152 has a large free inner diameter and an adjustable range from 100mm. Furthermore
