TS-Optics PHOTOLINE 130 mm f/7 FPL53 Triplet Apo - 3.7" Focuser

Photoline 130 mm f/7 Deluxe Apo - a refractor without compromiseThe 130 mm f/7 apo triplet refractor is equipped with one of the best objectives in its class. For the apo element the proven FPL53 from Ohara (Japan) is used. The objective lens without chromatic aberrations is mounted in a temperature-compensated cell that also compensates for minus temperatures. The powerful lens is very popular especially with astrophotographers, so we now offer this apo with the large 3.7" RPA focuser. This means that CCD cameras with large sensors can also be used and with all common correctors even for full-frame format.Advantages and features of the PHOTOLINE 130 mm F7 Deluxe Apo:♦ Air-spaced triplet lens - apo element from FPL53 by Ohara ♦ Temperature compensated, fully-adjustable cell ♦ 3.7" Photoline RPA rack and pinion duial-speed focuser - hods accessories up to 8 kg with 360° rotation ♦ Sturdy aluminium tube with internal baffles against stray light ♦ Convenient carrying handle and GP/EQ5 style dovetail on one side and a Losmandy style dovetail bar on the other one ♦ 100 mm long spacer between focuser and tube screwed with M123x1 thread on both sidesThe 3.7" RPA focuser - ball bearing mounted:A highlight of the telescope is certainly the modern "rack and pinion" focuser with cograil adjustment and ball bearings. The large dimensioned focuser also allows the use of full format and large format cameras without vignetting, of course with the appropriate correctors.♦ Adjustment via gear rack - no friction - no yielding as with the Crayford focuser ♦ Internal baffles against reflexes ♦ Clear aperture: 102 mm ♦ Adjustment range of the drawtube: 100 mm ♦ 360° rotation for optimal selection of the field of view ♦ Self-centering 2" and 1.25" adapters for correct clamping on the optical axis ♦ Connection thread for photo adaptations: M100x1 female thread, M92x1 female thread, M68x1 ZEISS style female thread and of course 2" and 1.25" receptacles ♦ The working distance is optimized for all common correctors and also for visual observation. ♦ Binoviewers with 2" star diagonal mirror can be used without glass path compensation, only the 100 mm spacer needs to be removed.Recommended astrophotographic correctors for the PHOTOLINE Apo:TSFLAT3 - large format corrector without changing the focal length♦ The corrector fits directly onto the M92x1 internal thread of the focuser. ♦ The recommended working distance is 103 mm. ♦ Included in delivery is a reduction to M48 - 2" filter thread. From this thread it is 55 mm to the optimal position of the camera sensor - ideal for DSLR cameras.TS 0.79x PHOTOLINE focal reducer and corrector - TSRED379♦ The corrector fits directly onto the M68 connection thread of the focuser ♦ The focal length is reduced to 719 mm, the focal ratio improves to f/5.53 ♦ Recommended distance from the M48 connection thread of the corrector to the sensor: 55 mm ♦ The PHOTOLINE reducer is suitable for cameras with full format sensors or smaller.TS 0.75x focal reducer and corrector - TSAPORED075♦ The corrector fits to the M68 connection thread of the focuser with the adapter TSM82-M68 ♦ The focal length is reduced to 682 mm, the focal ratio improves to f/5.25 ♦ Recommended distance from the M48 connection thread of the corrector to the sensor: 55 mm ♦ The PHOTOLINE Reducer is suitable for cameras with full frame sensors or smaller.
