TS PHOTOLINE 106 mm Triplett Apo for first class astrophotos
The Photoline apochromat with the color-pure premium triplet objective from Hoya (Japan) is the optimal solution for astrophotography. The apo offers a clear image with sharp stars up to the edge. During observation, the apo also convinces with strong contrast and high-contrast imaging up to the highest magnification range. The apo is designed for astrophotographers who value an optically and technically sophisticated solution. The image field corrector for cameras up to full frame is already included in the scope of delivery - a complete solution that meets even high demands.
Astrophotographic results obtained with this telescope on Astrobin
Here you can find some astrophotographs made with this telescope model:

The apo shows you lunar craters or planets without chromatic aberration with a contrast that only a refractor is capable of. But also bright stars are imaged without disturbing color fringes. The reason is the high quality triplet objective with the special glass FCD100 from Hoya in Japan. This glass corresponds in the correction to the well-known FPL53.
The air-spaced triplet objective is mounted in a stable, temperature-compensated cell. The complete cell can be adjusted with tension and compression screws. So collimation is not done by lateral pressure on the lenses and is therefore much more accurate and better for the image.
The 3-element 0.75x image field corrector for sharp stars up to the edge
The corrector is already included in the scope of delivery. It is screwed to the focuser via the M63x1 thread. Especially for the corrector, Teleskop-Service has put a lot of emphasis on a very good solution.
0.75x shortening factor - the focal length is reduced to 525 mm, the focal ratio is improved to fast f/4.95; 55 mm to 60 mm working distance - finely adjustable with 0.05 mm accuracy - from M48x0.75 thread; Adapter from M82x0.75 to M48x0.75 with 6.4 mm overall length included for individual adaptations; 3-element design with ED special glass; Multi-coating and field stops avoid reflections and improve contrast;3.5" hybrid focuser for maximum load
To allow you to connect heavy accessories to the focuser, the focuser is equipped with a special bearing. It doesn´t just have ball bearings pressing against the draw tube, which give way under higher loads. A rail is attached to the draw tube, which is perfectly supported by adjustable ball bearings. This means that no tilting can be observed, even with heavy accessories weighing up to 10 kg.
The drive itself is decoupled and is achieved by means of a helical gear. This guarantees fine and even adjustment even with heavy accessories. The 1:10 speed reduction enables even more precise focusing. Fixation of the focus position is achieved by locking the adjustment wheel. No screw presses on the draw tube.
In addition to the 2" and the 1.25" receptacle for visual observation, the focuser also offers the M63x1 female thread and the M78x1 female thread for screwed adaptations.
360° rotation for the right camera position
The focuser itself is fixed to the tube. But many astrophotographers prefer a 360° rotation of the camera for the right image orientation. We offer a solution. You need 2 items for this:
TSROTM63 (360° rotation) and M68a-M63i (reduction from M68x1 to M63x1)This results in a precise 360° rotation with only 21.9 mm overall length. The rotator is screwed between the focuser and the corrector. Of course, you can focus without any problems.
More information on Hoya´s FCD100 APO element:
FCD100 is an ultra-low dispersion optical glass almost equivalent to fluorite (CaF
2). With this glass, in combination with high refractive index optical glasses, excellent chromatic aberration (color error) correction can be achieved. The difference in dispersion performance to FPL53, for example, is less important than the difference in how well the optics are polished. FCD100 is Hoya´s name for this special glass, just as FPL53 is Ohara´s proprietary name.
