TS PHOTOLINE 96 mm Triplet Apo for first-class Astrophotography and Observation
The 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:
TSRED94 - 0.92x corrector up to full frame formatThe corrector was calculated especially for this apo and brings optimal results. The focal length is shortened to 530 mm and the focal ratio is improved to f/5.52. The corrector is calculated for sensors up to full format and has a working distance of 55 mm. This corrector is also directly screwed to the focuser with the M63x1 thread.
TSFLAT25DEL 1.0x full frame correctorThe apo is already very fast at f/6. 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 take advantage of 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 format360° rotation for selecting the correct image sectionThe focuser does not offer a rotation option, it is fixed and screwed to the tube. However, between the corrector and the focuser, you can insert a short-bodied rotator, the TSROTM63K. The rotator is solid and will support heavy cameras. Due to the tapered clamping system, tilting is impossible.
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 (CaF
2). 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.
