TS-Optics NEWTON Coma Corrector 1.15x for big sensors - 3" Connection

TS N-AGK3 3" Newtonian Coma Corrector with best possible illumination

Teleskop-Service designs and manufactures the successful ONC and UNC Newtonian telescopes for years. Increasingly often, we are asked about an optimal coma corrector for these telescopes. With the N-AGK3, we are pleased to offer you one of the most versatile coma correctors on the market, with convincing characteristics and at an affordable price.

Properties of the N-AGK3 Coma Corrector:

♦ 100% illuminated and corrected field: 54 mm diameter at f/4
♦ Working distance: 69.3 mm from the M68 thread (telescop side) 
♦ Length 5.125" / 130 mm
♦ Focal length extension : Factor 1.14x

Telescope side adaption:

The N-AGK3 corrector has a 3" barrel, so the focuser has to accept 3" accessories. This requirement is fulfilled by focusers like the big JMI Event Horizon 3" focusers or the UNCN3 focusers

♦ This TS N-AGK3 corrector: length 130 mm + working distance 73 mm. Through the extension factor of 15%, this distance is fully compensated. The real focus is located only 130 mm above the tube.At f4, the fully illuminated field, limited by the field lens of the corrector, is approximately 50 mm. Thereby, the secondary can be dimensioned significantly smaller - approx. 30% of the aperture.

We recommend buying also an M68 adapter with this product. 

♦ Suitable for Newtonian telescopes up to f/3

♦ The best illumination in its class - f/4 Newtonians have 100% illumination over 54 mm field!

♦ M68x1 ZEISS level connecting thread at camera side - optimal working distance: 69.3 mm with the optional adapter VIP3010-M68 (look to "customize your product")

♦ does not induce spherical or chromatic aberration

♦ Suitable for 3" focusers

♦ Focal length extension 1.14x

♦ Focus shift 73 mm outwards - the corrector needs a focal position of only 130 mm above the tube.
