TS-Optics 80 mm f/5.6 FPL53 Apo with corrector for astrophotography - BUNDLE

Affordable travel apo refractor for astrophotography and observation with very good optics

The 2-element objective convinces with a very good color correction through the use of FPL53 and lanthanum glas. The color correction is comparable to an FPL53 triplet. Even at high magnification, no disturbing color error will be visible.

The 0.8x field corrector, which we also offer in this Astrofoto bundle, has been developed for 2-element lenses with 80 mm and offers very good correction and illumination up to APS-C format, but the corrector can also be used for full format. The connection to the apo is made via the M63x1 thread, tilting is impossible. If you unscrew the M48 adapter on the camera side, an internal thread for 2” filters is supported.

Astrophotography with the apo

This package offers an inexpensive solution for mobile photographic use. No compromises were made in the quality of the lens and the mechanics. The image can certainly compete with significantly more expensive apos. The corrector is optimized for cameras with APS-C sensors but it also can used with full-frame sensors. Very good results are therefore possible. A good 1.0x flattener, which even allows use up to full frame, is linked in the "accessories" section. So the telescope can grow with your requirements.

Best mechanics guarantee an excellent image during photographic use

Good optics only work if the mechanics are also right. This apo fulfills these criteria.

Ball-bearing mounted 2.5" focuser with rack & pinion drive. The bearing is decoupled from the adjustment of the draw tube.

Oversized focuser tube with 60 mm clear aperture for full illumination even with full-frame sensors.

1:10 dual speed for ultra-precise focusing

High-quality CNC tube with internal baffles and very good internal blackening - no disturbing stray light

Female M63x1 thread allows stable screwed adaptations for astrophotography

The dew shield can be retracted - the transport length is then only 46 centimeters

High-quality CNC rings and GP-style dovetail bar with photo tripod connection

The visual use - spotting scope and astronomical telescope

Although the apo is optimized for astrophotography, it can also 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" diagonals or Amici prisms and magnify up to about 200x with very high contrast.
