TS Optics Apochromatic refractor AP 115/800 ED Triplet Photoline OTA (51023)

The TS Optics Apochromatic Refractor AP 115/800 ED Triplet Photoline OTA is a high-performance telescope designed for advanced users, especially those interested in astrophotography. Its triplet lens system, made from lanthanum glass and FPL51 by Ohara, Japan, provides superior correction and minimizes color errors, resulting in sharp, high-contrast images. The air-spaced, multi-coated lens is housed in a temperature-compensated, non-tensioned frame, and is fully adjustable for optimal performance. With its fast focal ratio, this telescope enables short exposure times and is suitable for capturing a wide range of celestial objects, from extended nebulae to small galaxies.

TS Optics is a brand of Teleskop-Service.
