TS-Optics PhotoLine 102mm f / 7 FPL53 Dublet ED-Apo refractor with 2.5 "OAZ

Apochromatic refractor of telescope service with very well corrected lens and best mechanics for astrophotography and observation.

♦ aperture 102 mm / focal length 714 mm / aperture ratio f / 7

♦ Adjustable Dublet lens in temperature compensated socket

♦ Pure Color Image with "Extra Low Dispersion" FPL53 Apo element from Ohara (Japan) and Lanthanum element - we achieve better color correction than comparable Apos with Dublet lenses.

♦ Shorter cooling time than with Triplet lenses, allowing for faster deployment

♦ Inner panels for a high-contrast image

♦ One of the best 2.5 "eyepieces in its class with 360 ° rotation, ball bearing - adjustment via rack - with micro reduction - motor focus can be retrofitted

♦ The dew cap can be inserted for transport. Transport length is only 60 centimeters.




TS-Optics PhotoLine 102mm f / 7 Dublet FPL53 Apo

This Apo from the PhotoLine series by Teleskop Service offers a very good performance in every application. The combination of FPL53 (Ohara-Japan) and the lanthanum element achieves a color correction equivalent to that of an FPL53 triplet - with significantly faster cooling. Even at the highest magnification, the image remains free of annoying color errors. Thus, the high-intensity refractor is very well suited not only for astrophotography and large-field observation, but also for the moon and planets.

Very good mechanics guarantees enjoyment of the telescope and universal application possibilities
The new PhotoLine 102 mm Apo offers not only the latest-generation lens but also mechanical equipment that leaves nothing to be desired. Thus, the performance of the lens can be photographically and visually fully implemented.

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

♦ 102mm f / 7 FPL53 / Lanthanglas lens for pure color picture
♦ Ball-bearing focuser with Rack & Pinion (pinion) adjustment. The storage is decoupled from the adjustment of the extension tube.
♦ Oversized pull-out tube for full illumination even in full format.
♦ 1:10 micro reduction for precise focusing.
♦ Motorized focusing can be retrofitted.
♦ M63x1 internal thread for screw adaptations and 2 "/ 1.25" for plug-in adaptations available
♦ Inner panels and very good interior blackening for high-contrast imaging
♦ Retractable dew cap for easier transport
♦ CNC clamps and GP level prism rail included

The photographic use - a telescope, two focal lengths

The Photoline f / 7-Apo is fully suitable for astrophotography, as with any bright refractor, however, the field must be corrected so that the stars are still nice and round at the edge. We offer the following options, the correctors are linked in the accessories area.

♦ TSFlat2 - universal 2 "image field corrector without focal length change: The corrector is inserted directly into the 2" socket and clamped with the adapter kit. The working distance is 111 mm from the M48 connection thread of the corrector. With the TSFlat2A you get the complete adaptation to your camera supplied by us. We recommend the TSFlat2 for cameras up to APS-C format.

♦ TSFlat2.5 - 2.5 "image field corrector without focal length change: The corrector is screwed to the M63 connection thread using the adapter M63a-Flat25 The working distance from the M69 connection thread of the flattener is 91 mm We recommend the TSFlat2 , 5 for cameras with full-format sensors.

♦ TSRed279 - 2 "Photoline Reducer and Corrector: The 0.79x corrector reduces Apo's focal length to 564mm and increases the aperture from f / 7 to f / 5.53, and the reducer is plugged directly into the 2" Plug-in sleeve clamped. The working distance from the T2 thread is 56 mm. We recommend the Reducer for cameras up to APS-C format sensors.

♦ TSRed279 - 2 "Photoline Reducer and Corrector: The 0.79x corrector reduces Apo's focal length to 564mm and increases the aperture from f / 7 to f / 5.53, and the reducer is plugged directly into the 2" Plug-in sleeve clamped. The working distance from the T2 thread is 56 mm. We recommend the Reducer for cameras up to APS-C format sensors.

♦ TSRed379 - 3 "Photoline Reducer and Corrector: This 0.79x corrector also reduces the focal length to 564 mm and increases the light intensity to f / 5.53 The working distance from the M48 thread is 56 mm screwed to the M63 connection thread, you will need the M63a-M68i adapter We recommend the Reducer for CCD cameras with larger sensors and for DSLR cameras with full-format sensors.
