TS PHOTOLINE 107mm f/6.5 Super Apo with 3" rack and pinion focuser and divisible tube

The 107/700mm apochromat is free of colour aberrations and very well suited for visual observations and astrophotography. Thanks to FPL53 from Ohara, the imaging quality of the triplet APO is excellent and, in practice, cannot be distinguished from the world-famous LZOS objectives from Russia.

The objective of the TS 107/700mm apo:

The triplet lens with 107.2 mm aperture and 700 mm focal length meets the criteria of a true apochromat. Even at a magnification of 400x, the image is free from bothersome colour aberrations. On astro images, even bright stars are shown without annoying blue fringe.

The APO element is made of FPL53 from Ohara, Japan. The air-spaced triplet objective is fully adjustable. All air-to-glass surfaces are multi-coated. The lens is mounted into a temperature-compensated, adjustable cell.

The photographic 3" rack & pinion focuser:

The 3" CNC focuser is optimised for photography and holds up to 6 kg load. The adjustment of the drawtube is made by rack and pinion. The construction of the focuser is base on the Starlight Feather Touch and the mechanical stability gets definitely close to the Starlight Feather Touch FTF3035. We offer motorized focusing for the focuser, too.

High-quality metal tube:

A special service from Teleskop Service. We deliver the tube with two additional segments which are threaded between focuser and tube. The precisely manufactured extensions reduce the distance of the focus to the focuser and prevent the draw tube from being extremely extended. The result: higher stability and no tilting even when heavy cameras are used.

♦ Shortest position - no segment ... suitable for the M63 Riccardi Reducer 0.75x RIRED-M63 for full-frame format and for bino viewing without glass path corrector (with 1.25" star diagonal)

♦ Medium position - one segment ... suitable for the TS 2.5" full frame flattener

♦ Longest position with both extensions ... suitable for visual observations with 2" star diagonal mirror

Photographic usage - one telescope, two focal lengths for photography!

Focal length 525 mm / focal ratio f/4.9 with RICCARDI Reducer ... The flexible focus position, due to the modular tube, allows using the outstanding 0.75x Riccardi reducer. The focal length is reduced to 525 mm and the speed is increased to f/4.9! At the same time, sensors up to 42 mm diameter are fully illuminated.

The reducer is screwed to the M82 thread of the focuser. For this, you need the adapter TSM78-M82. Both tube segments are removed. From the female M82x1 thread at the camera side to the camera sensor, the optimal distance is 78.3 mm.

Focal length 700 mm / Focal ratio f/6.5 with 2.5" full-frame flattener ... With the TS 2.5" full-frame flattener, you can achieve 100% illumination with full-frame sensors, too.

For attaching the TSFlat2,5 to the focuser, no adapters are necessary, the flattener fits directly to the focuser. One tube segment is removed. From the female M69 thread at the camera side to the camera sensor, the optimal distance is 99 mm.
