Teleskop-Service The new Photoline apo from TS Optics offers a very good performance in virtually every area of observation and astrophotography. The imaging quality sets standard in this class. In the lens, the “extra low dispersion” glass FPL53 from Ohara (Japan) is used. This high-quality apo element and the relaxed focal ratio of 1:7 allow for an image virtually free of chromatic aberration. Through the doublet lens, a faster cooling is achieved, too.Best mechanics ensure an outstanding imaging performance for years and success in astrophotography. Even the best optics can only be successfully used if the machanics is right. Here, savings are often made at the wrong end. This is not the case for the Photoline 80 mm f/7 apochromat.
