TS-Optics CF-APO 155mm f/8 FPL55 triplet apo
Teleskop-Service's Biggest Apo is the inexpensive entry into the world of really big refractors. Such a telescope offers joy for a lifetime and is an ornament in every observatory. This apochromatic refractor offers a number of interesting features:
♦ Triple apochromatic lens with FPL55 as APO element and additional special lanthanum glass for even better color correction.
♦ Improved frame for even more adjustment stability, the frame can be adjusted using tension and pressure screws.
♦ A very good 3.7" rack and pinion focuser. The focuser has ball bearings for precise adjustment even under high loads, eg from heavy cameras.
♦ Wide 140mm working distance from the 2" barrel, which can be extended with a removable segment between the tube and focuser. The focuser fits directly into the tube. It is even possible to use binoculars without glass path compensation.
♦ Each Apo is supplied with a manufacturer's test certificate. The apochromat receives a serial number. Furthermore, every apo in Teleskop-Service is tested on the optical bench and optimally recalibrated.
Astrophotography through the TS 155mm Apo
In principle, Apo can be combined with all suitable correctors. We highly recommend the following concealers, which are linked in the recommended accessories.
TSFLAT3 - Checker 1.0x
The corrector screws directly onto the M92 thread of the focuser. The corrector offers illumination and correction of up to 60mm image circle diameter. The focal length does not change.
TSRedJM63B - Corrector 0.8x
The corrector screws directly onto the M63 thread of the focuser. It reduces the focal length to 992mm and improves the aperture ratio to f/6.4. The corrector offers illumination up to 42mm image circle diameter.
TSAPORED075 - Corrector 0.74x
The corrector is screwed to the focuser with the adapter M92A-M88i (optional, linked in the accessories area). It reduces the focal length to 917mm and improves the aperture ratio to f/5.92. The corrector offers illumination up to 44mm image circle diameter.
