TS-Optics PhotoLine 102mm f/7 FPL-53 Doublet Apo with 2.5" Focuser

Apochromatic refractor from Teleskop Service with very well corrected object lens and best mechanics for astrophotography and observation.

  • ♦ Aperture 102 mm / focal length 714 mm / focal ratio f/7

♦ Adjustable doublet in temperature compensated cell
♦ Image free of chromatic error due to "Extra-Low-Dispersion" FPL53 apo element from Ohara (Japan) and Lanthanum element - with this, we achieve a better chromatic correction than comparable apochromats with doublet lenses.
♦ Shorter cooling time than with triplet lenses, thus quicker operation possible
♦ Internal baffles for a more contrasty image
♦ One of the best 2.5" focusers in its class, with 360° rotation, ball bearings - adjustment via pinion - with dual speed gear - motor focus can be retrofitted
♦ M63x1 thread (female), 2" and 1.25" receptacle are available
♦ CNC tube rings and GP style dovetail bar are supplied
♦ Dewcap retractable for transport. Transport length only 60 centimetres.

TS-Optics PhotoLine 102mm f/7 Dublet FPL53 Apo
This apochromat from the PhotoLine series from Teleskop Service offers very good performance in any application area. By combining FPL53 (Ohara, Japan) and a lanthanum element, a chromatic correction is achieved which matches the one of an FPL53 triplet - with significantly quicker cooling down. Even at highest magnification, the image remains free from distracting chromatic aberration. This means that the fast refractor is not only very well suited for astrophotography and wide-field observation, but also for moon and planets.

Very fine mechanics guarantees joy with the telescope and universal application capabilities
The new PhotoLine 102 mm apo offers, besides a lens of the latest generation, also a mechanical equipment which leaves nothing to be desired. Thereby the performance of the lens can be fully implemented photographically or visually.

Advantages and features of the PhotoLine 102mm f/7 apo:

♦ 102mm f/7 FPL53/lanthanum glass lens for an image free of chromatic aberration
♦ Ball bearing supported focuser with rack & pinion adjustment. The support is decoupled from the adjustment of the draw tube.
♦ Overdimensioned draw tube for full illumination even with full-frame format.
♦ 1:10 speed reduction for precise focusing.
♦ Motorized focusing can be retrofitted.
♦ M63x1 thread (female) for threaded adaptions and 2" / 1.25" for pushed adaptions
♦ Internal baffles and very good internal blackening for contrasty images
♦ Retractable dew cap for easy transport
♦ CNC tube rings and GP style dovetail bar in the scope of delivery

Photographic use - one telescope, two focal lengths
The Photoline f/7 apochromat is fully suitable for astrophotography, however, like with any fast refractor, the field has to be corrected so that even the stars at the edge are nicely round. For this, we offer the following choices, the correctors are linked in the accessories section.

TSFlat2 - universal 2" field corrector without change of the focal length: The corrector is directly inserted into the 2" receptacle and locked with the adapter kit. The working distance is 111 mm form the M48 thread of the corrector. With the TSFlat2A, you get the complete adaption to your camera from us. We recommend the TSFlat2 for cameras up to APS-C format.

TSFlat2,5 - 2.5" field corrector without change of the focal length: The corrector is screwed with the M63 connection thread. For this, the adapter M63a-Flat25 is necessary. The working distance drom the M69 thread of the flattener is 91 mm. We recommend the TSFlat2,5 for cameras with full-frame sensors.

TSRed279 - 2" Photoline reducer and corrector: The 0.79x corrector reduces the focal length of the apo to 564 mm and increases the speed from f/7 to f/5.53. The reducer is directly clamped into the 2" receptacle. The working distance from the T2-thread is 56 mm. We recommend the reducer for cameras with sensors up to APS-C format.

TSRed379 - 3" Photoline reducer and corrector: This 0.79x corrector reduces the focal length also to 564 mm and increases the speed to f/5.53. The working distance from the M48 thread is 56 mm. The reducer is screwed together with the M63 connection thread. For this, you need the adapter M63a-M68i. We recommend the reducer for CCD cameras with larger sensors and for DSLR cameras with full-frame sensors.
