The new Photoline apochromat with the color-clean premium triplet lens with glasses from Hoya (Japan) is the optimal solution for astrophotography and for observing. The lens with cell is completely manufactured in Japan. Due to the triplet 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. The stars are imaged without disturbing color fringes and the image on moon and planets does not become soft even in the highest magnification range.

Astrophotography with the TS Photoline 96 mm f/6 apo:

At f/6, the apo is already very fast. This often eliminates the need to use a focal length reducer to improve the focal ratio. The TS-Optics Photoline 1.0x corrector # TSFLAT25DEL is suitable if you want to use the full focal length.

♦ Screws directly to the M63x1 female thread on the focuser
♦ Problem-free reaching of the focus
♦ Working distance 55 mm from the M48 connection thread of the corrector
♦ 2" female thread for 2" filter is available
♦ Illumination and correction up to full format

Alternatively, we offer # TSRED94, a 0.92x corrector specially designed for the TS Photoline 96 mm f/6 apo. The focal length is shortened to 530 mm and the focal ratio is improved to f/5.52. The corrector is designed for sensors up to full format and has a working distance of 55 mm. This corrector is also directly screwed to the M63x1 thread of the focuser. This corrector is specially calculated for this refractor and is also our recommendation for photographic use.

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 rail bearing opposite the adjustment keep the draw tube in position even under heavy loads.

The adjustment itself is decoupled and is achieved via a helical gear. This guarantees fine and smooth adjustment even with heavy accessories. The 1:10 dual speed allows for 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 for screw adaptations for astrophotography.

360° rotation for correct camera position and quick coupling

The focuser is fixed to the tube. A short rotation option is provided by the # TSROTM48 adapter. This rotation comes on the M48 camera thread of the TSFLAT25G2 corrector instead of the 10 mm extension adapter. The adapter is only 8.5 mm short, you can overcome the remaining 1.5 mm with the M48 tuning ring # M48Abstimmring2. This way, you have the correct working distance of 55 mm again and can even remove or rotate the camera from the corrector in just a few steps.

More information about the FCD100 APO element from Hoya:

FCD100 is an extremely low dispersion optical glass corresponding to fluorite (CaF2). With this glass, in combination with high refractive index optical glasses, excellent correction of chromatic aberrations can be achieved. The difference in dispersion performance to 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 single telescope before shipping:

♦ Cosmetic check for dust and scratches
♦ Mechanical inspection, optimal adjustment of the focuser
♦ Collimation of the objective and subsequent optical inspection on our optical bench
