TS-Optics 80 mm f/6 FPL53 Triplet SuperApo with 2" Feather Touch focuser - with optical test

TS 80 mm f/6 FPL53 Triplet Super Apo

Our aim was to find a worthy successor to the legendary 80 mm LOMO triplet apo that would meet the highest standards both optically and mechanically. With the TLAPO804-FT, we have succeeded. The refractor is one of the best telescopes in its class and is an ideal travel telescope. Astrophotographers and nature observers will be delighted with this telescope.

The 2" Starlight Feather Touch focuser FTF2008BCR

An exact adjustment and precise clamping is not only enormously important for astrophotography. Too often the actually good optical performance of the lens is reduced by mediocre mechanics. Not so with this TS 80 mm f/6 Super Apo. We have used the best focuser we could find - without compromise.

The FPL53 objective of the TS 80/480 mm Super Apo

The objective was tested, the graph shows the color deviation in relation to the wavelength of the light. The result is clear, even at magnifications of over 200x, the image remains practically free of errors. No color error will be visible. If the telescope is used for astrophotography, even bright stars will not show any blue color fringing, as is the case with doublet objectives or triplet objectives with FPL51 or similar apo elements.

This is how we hand over the apo to the amateur:

Every single APO is checked in our technical department before it is put into storage, in order to guarantee a consistently high product quality.

The mechanics are tested and the focuser is optimally adjusted.

The lens is cosmetically checked and cleaned. We also check that all counter screws are correctly tightened. These often loosen during transportation.

The optics are collimated and the result is checked on the optical bench. The telescope is given a serial number.

An optical test is carried out, which is enclosed with the telescope (star images and ronchi image on the optical bench in autocollimation).

Only then are the telescopes handed over to the warehouse and prepared for dispatch.

Beweis für die Farbreinheit des Triplet APOs: Herr Werner Mehl hat mit einer Bahtinov Maske die Schärfeeinstellung am TS Triplet Apo 80/480mm fotografiert. Obwohl die Durchlassbereiche der einzelnen Filter im sichtbaren Spektrum verteilt sind, war ein Nachfokussieren zwischen den einzelnen Filtern nicht nötig. Die Schärfeeinstellung konnte unverändert so belassen werden. Das ist ein wirklicher Beweis dass der Apo exakt die gleiche Schärfeebene von Blau bis Rot hat. Wir kennen vergleichbare Ergebnisse nur von deutlich teureren russischen APOs. Herzlichen Dank für diese aufschlussreiche Dokumentation.
