TS-Optics 102mm f/5.5 FPL53 Apo with 3-element corrector for astrophotography

TS 102 mm FPL53 / lanthanum glass apo and 3-element full-frame corrector - bundle for astrophotography

The SD apochromat with the 2-element objective convinces with a color-pure image in focus thanks to the two special glasses. The mechanical features, such as the 2.5" RAP focuser with the M68x1 screw thread, the internal baffles in the tube or the CNC rings leave nothing to be desired.

The 3-element 0.79x full-frame corrector from the Photoline series is not designed for the lens, but it works very well and ensures good correction up to full frame. The corrector is screwed directly to the M68x1 thread of the focuser. Nothing is plugged in. Because this corrector and this apo go very well together, we offer this combination for astrophotographers.

Very good mechanics and optics also guarantee excellent photographic imaging properties:

102 mm f/7 FPL53 / lanthanum glass objective for imaging without relevant chromatic aberration

Ball-bearing focuser with rack & pinion adjustment. The bearing is decoupled from the adjustment of the draw tube.

Oversized draw tube for full illumination even with full frame sensors.

1:10 dual speed for precise focusing.

Motorized focusing can be retrofitted.

M68x1 internal thread for screw adaptations and 2" / 1.25" for plug-in adaptations available

Internal baffles and very good internal blackening for high-contrast image

Retractable dew shield for easier transportation

CNC rings and GP style dovetail bar included in the scope of delivery

Proven 3-element corrector with special ED glass

Reflection-free due to multi-coating and clean internal blackening.

The visual use as astronomical telescope

The apo can of course be used very well visually. Simply unscrew the corrector and insert the 2" receptacle. Now you can observe through the telescope with 1.25" or 2" star diagonals or Amici prisms and magnify up to about 300x with very high contrast.
