TS N-AGK3 – 3″ Coma Corrector fr Newtonian telescopes up to f/3
The TS N-AGK3 eliminates the coma, which emerges at Newtonians, for astrophotography – this 3″ vrsion is also suitable for cameras with large sensors. Suitable for Newtonian telescopes up to f/3
The best illumination in its class what we know – f/4 Newtonians have 100% illumination over 54 mm field!
M68x1 Zeiss level connecting thread at camera side – optimal workingdistance: 69.3 mm
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.
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 (see accessory recommendations).
Camera side adaption:
Thanks to the M68x1 thread connection, you can attach the entire programme of M68 accessories, like our M68 off axis guider. The camera itself has only 1 mm length, so you have 69.3 mm working distance from the M68x1 thread. That offers enough space for generous adaptations. If filters are used, you should add 1 mm to the working distance.
