TS-Optics APO Refractor 85/510mm - FCD100 Triplet Lens from Japan

TS PHOTOLINE 85mm Triplet Apo for first-class astrophotography and observing

The new Photoline apochromat with the clean color premium triplet lens with spectacles from Hoya (Japan) is the optimal solution for astrophotography and observation. The cell lens is completely made in Japan. Due to the triple objective, the apo convinces with strong contrast and a high contrast image up to the highest magnification range. The apo has also been developed for astrophotographers who value an optically and technically sophisticated solution. Star images are obtained without disturbing color fringes and the image of the moon and planets is not softened even at the highest magnification range.

Astrophotography with the TS Photoline 85mm f/6 apo:

The 3-element 0.92x image field corrector for sharp stars to the edge has been specially developed for this telescope. The corrector is linked in the accessories section. It is screwed to the focuser using the M63x1 thread. Especially for the corrector, Teleskop-Service has put a lot of emphasis on a very good solution.

♦ 0.92x reduction factor: focal length reduced to 469mm, focal ratio improved to fast f/5.52;

♦ working distance from 55mm to 60mm - finely adjustable with precision of 0.05mm - from thread M48x0.75;

♦ Screw connection directly to the female thread M63x1 of the focuser.

2.5" hybrid focuser for maximum load

To allow you to connect even heavy accessories to the focuser, the focuser is equipped with a special bearing. Ball bearings and a solid anti-adjustment rail bearing keep the drawtube in position even under heavy loads.

The adjustment itself is decoupled and is achieved through a worm gear. This fine and smooth adjustment even with strong guarantees. Dual 1:10 speed enables even more precise focus. Fixing the focus position is achieved by locking the adjustment wheel. No screw presses on the extraction tube.

In addition to the 2" and 1.25" receptacle for visual observation, the focuser also offers the M63x1 female thread for screw adaptations for astrophotography.

360° rotation for correct camera position and quick coupling

The focuser is attached to the tube. The quick coupler and rotation adapter #TSROTM63 offers a short rotation option. This rotation is used between the corrector and the focuser's M63x1 female thread. This allows you to rotate the camera with corrector or remove it completely from the telescope in just a few steps.

More information on the Hoya FCD100 APO element:

FCD100 is an extremely low dispersion optical glass corresponding to fluorite (CaF2). With this glass, in combination with high refractive index optical lenses, excellent correction of chromatic aberrations can be achieved. The difference in dispersion performance versus FPL53, for example, is less relevant than the difference in how well polished the optics are. FCD100 is Hoya's name for this special glass, just as FPL53 is Ohara's proprietary name.

So we hand over the apos to the amateur astronomer:

Our goal is that you have pleasure with this apo from the beginning. That's why we check every telescope before we ship it:

♦ Cosmetic dust and scratch control.

♦ Mechanical inspection, optimal adjustment of the focuser

♦ Collimation of the objective and subsequent optical inspection in our optical bench
