According to EU law, we have to display different, country-specific VAT rates in our online shop. In doing so, we try as best we can, the country of origin of our visitors from the IP of the requesting browser. This usually works, but not always. Only after logging in, the country of origin is definitively known, and the VAT rate is always displayed correctly in every case.


TS-Optics NEWTON Coma Corrector 0.73x Reducer - 2" Connection

This coma corrector and reducer turns your Newtonian telescope into a high-speed astrograph. The focal length is reduced and the field is corrected.

♦ This 2" reducer and coma corrector has been developed by Ackermann, a well-known US optics designer, and is manufactured exclusively for Teleskop-Service.

♦ The corrector reduces the focal length of the Newtonian and increases speed while correcting the field at the same time.

♦ The corrector can be used with all Newtonian telescopes from f/3.5 to f/8. Prerequisite is just a 2" connection and sufficient working distance (backfokus)

♦ The existing design was clearly improved at the same time, the usable field is larger and the illumination was improved.

♦ Shortening factor 0.73x

♦ Working distance from the M48 thread ist 67 mm

♦ Usable field up to 30 mm (APS-C size) / fully corrected 22 mm

♦ Necessary focus distance from the 2" receptacle of the focuser: 85 mm - that is fulfiled by almost all Newtonian telescopes with 2" connection

♦ Mechanical length of the corrector is 56 mm - it is short and does not protrude into the tube. The shorter design also provides a larger illuminated field of view

♦ At the telescope side, an M48x0.75 2" filter thread is available
