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 66.85 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 

Newtonian Coma Corrector and 0.73x Focal Reducer for your Newtonian telescope. This corrector increases the speed of your Newtonian telescope and corrects the Newtonian coma. The exposure times can be halved. The corrector was designed by H. Ackermann (USA). The corrector is usable for the following Newtonian telescopes: Basically, the corrector/reducer can be used with all Newtonians from f/3.5 to f/8. It has an M48 thread at the camera side. A further adaption is not problematically and can be planned to one millimetre.

The adapter shifts back the focal plane by 15-16 millimetres. This value results from the reduction factor of the reducer. You need approximately 85 mm from the 2" receptacle of the focuser to the focus to make the reducer operational. UNC and ONTC Newtonian telescopes from Teleskop Service can be prepared for the use of this special corrector. Because of the increased speed, you have to pay attention on accurate clamping.

Even minimal tilting results directly into unsharp stars at the edge. Usable image field of the TS-Optics corrector-reducer: The design of the corrector allows for a usable field of 22 mm diameter with 100% illumination. With a little trick at focusing, this field can be extended to approx. 30 mm. Do not use a star in the middle of the field, but use a medium bright one in the outer third of the field.
