TS-Optics PhotoLine 102mm f/7 FPL-53 Doublet Apo with 2.5" Focuser

The telescope

This apochromat from the PhotoLine series from Teleskop Service offers very good performance in any application area. By combining FPL53 (Ohara, Japan) and a lanthanum element, a chromatic correction is achieved which matches the one of an FPL53 triplet - with significantly shorter cooling times. Even at highest magnification, the image remains free from distracting chromatic aberration. This means that the fast refractor is not only very well suited for astrophotography and wide-field observation, but also for moon and planets.

The mechanics

Very fine mechanics guarantees joy with the telescope and universal application capabilities. The new PhotoLine 102 mm apo offers, besides a lens of the latest generation, also a mechanical equipment which leaves nothing to be desired. Thereby the performance of the lens can be fully implemented photographically or visually.

Photographic use

The Photoline f/7 apochromat is fully suitable for astrophotography, however, like with any fast refractor, the field has to be corrected so that the stars at the image edge stay nicely round.
