Codice articolo: TSAPO805-Foto

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

The compact FPL53 / Lanthanum APO convinces with a image without chromatic error and solid mechanics, the corrector is optimized for 2-element lenses and offers good field correction.

Aperture 80 mm
Effective focal length with the 0.8x photocorrector 448 mm / focal ratio f/5.6
Focal length of the objective without corrector 560 mm
FPL53 / Lanthanum SD-APO objective without chromatic error
2-element 0.8x photocorrector - optimized for 80mm f7 doublet lenses - very good correction up to APS-C format
Working distance 55 mm from the T2 (M42x0.75) thread
Screw-in thread for 2" filter is available
2.5" RAP focuser with micro reduction for precise focusing - motorized focus can be easily retrofitted
2" adapter with reduction for 1.25" for observation with 2" and 1.25" accessories is included in the scope of delivery
Finder shoe for finder or guide scopes is mounted on the focuser

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 image field corrector, which we offer in this Astrofoto bundle, has been developed for 2-element lenses with 80mm and offers very good correction and illumination up to APS-C format. The corrector is simply inserted into the 2" receptacle. The special shape of the receptacle on the corrector prevents tilting, the stars will be point-shaped also in the corners.

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 sensors up to APS-C or smaller. 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 focuser tube.
Oversized focuser tube with 60 mm clear aperture for full illumination even with full-frame sensors.
1:10 micro reduction for ultra-precise focusing
High-quality CNC tube with internal diaphragms and very good internal blackening - no disturbing stray light
Female M63x1 thread allows stable screwed adaptations for astrophotography
The dew cap can be retracted - the transport length is then only 46 centimeters
High-quality CNC rings and GP-level 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.
