TS-Optics 80mm f/4.8 FPL53 Triplet Apo

The TS-Optics 80mm f/4.8 FPL53 Triplet Apo is a compact apo with FPL53 APO glass that is designed for observing and astrophotography offering a color-free image and solid mechanics.

TS-Optics 80mm f/4.8 FPL53 Triplet ApoThe TS-Optics 80mm f/4.8 FPL53 Triplet Apo incorporates a 3-element 0.8x field corrector that was developed for 80mm f/6 triplet apos and provides full correction up to full format. The corrector is screwed to the 2.5″ rack and pinion focuser to prevent tilting. The working distance from the M48 thread is 55 mm, which simplifies the adaptation of cameras. A 2″ filter thread is also integrated in the camera adapter.

Highlights of the TS-Optics 80mm f/4.8 FPL53 Triplet Apo include:

– Stiffly mounted focuser with rack and pinion adjustment. The storage is decoupled from the adjustment of the extension tube.

– Oversized extension tube with 60 mm free opening for full illumination even with full format.

– 1:10 micro reduction for ultra-precise focusing.

– High-quality CNC tube with inner screens and excellent inner blackening – no disturbing stray light.

– M63x1 internal thread on the drawtube.

– M68x1 internal thread on the connection adapter, to get to the thread, 3 grub screws must be loosened.

– The dew cap can be pushed in – the transport length is then only 37.5 centimeters.

– Modern and multi-coated 3-element lens with APO element made of FPL53.

– High-quality CNC clamps and GP-style prism rail with photo tripod connection.

– Pipe clamps have three at the top M6 threaded holes, one in the middle and two with a center distance of 30 mm.
