TS Photoline 80 mm f/6.25 FPL 53 Apo Telescope - 2.5" Focuser
High quality 3-element Apo, colourfree and with a very good mechanics - for highest demands - no vignetting in the edges
The 3-element Photoline 80 mm FPL53 apochromat
The Apo was substantially redeveloped by TS. The apochromat has one of the best 80 mm triplet lenses and a photographically optimized rack and pinion CNC focuser according to the principle of newer Starlight Feather-Touch focusers.
The carbon tubus offers maximum stiffness and a good thermal behaviour. The total weight of the telescope is only 3.48 kg including tube rings and dovetail bar. The result is a travel apochromat with an image free of residual color error and also with optimal spherical correction.
This telescope offers better illumination than any other refractor with this aperture. You can achieve a field of view up to 5.5° or increase magnification up to 200x without any decline of sharpness.
The advantages of the TS Triplet Apo 80/500 mm:
The object lens of the TS 80/500 triplet apochromat
- 80/500 mm triplet lens without colour blur - APO element made of FPL53 from Ohara (Japan)
- High-quality carbon fiber tube
- 2.5" CNC focuser - rotatable - with M63 connection thread for screw adaptions
- Dual speed for accurate focusing
- CNC tube rings / dovetail bar with slotted hole
- Retractable dew-cap - transport length only 350 mm with removed tube parts
The triplet objective offers a pure-coloured image, it fulfills the criteria of a true apochromat. The lens also offers best possible spherical correction and our experience has shown that it is on par with Russian lenses. The APO element comes from Ohara (Japan). The fully multicoated triplet lens is mounted into an adjustable cell and, of course, designed with air space.
The two diagrams above show objectively the outstanding image of the apochromat on the axis and in the field. We don´t know any objective with this aperture in this class with better imaging.
The 2.5" photographic focuser:
The large 2.5" focuser guarantees a maximum illuminated field. The focuser comes with an M63x1 thread, ready for the 0.75 x APM/Riccardi Reducer / Corrector or the 2.5" TS flattener. The focuser is superior to most of the Crayford focusers and even with highest payloads You won´t get any flexion problems.
The focuser also provides a 360° rotation and also a 1:10 dual speed.
One telescope - three focus positions:
Focal length 375 mm / focal ratio 1:4.7
The comfortable focus position allows using the outstanding Riccardi 0.75x reducer. The focal length is reduced to 375 mm and the speed is increased to f/4,5. At the same time, sensors up to 42 mm diameter are fully illuminated.
Focal length 500 mm / focal ratio 1:6.25
With the TS 2.5" full-frame flattener, you can achieve 100% illumination even with full-frame sensors. The less expensive TS 2" flattener is very well suited for sensors up to 30 mm diameter.
