Offer: TS-Optics PHOTOLINE 80 mm f/6 FPL53 Triplet Apo - 2.5" RAP Focuser

A perfect travelling apochromat - for observation and astrophotography

Under the lead management of Teleskop-Service, this high-quality Photoline triplet apo with FPL53 element from Ohara (Japan) came to life as optimal travelling apochromat.

Even at higher magnification, the image has no annoying chromatic error, with excellent correction at the same time. It is one of the best and fastest 80 mm apos we have seen. The fast focal ratio of f/6 not only keeps the refractor very short, it also provides short exposure times for astrophotography.

Best mechanics ensure an excellent image quality over years and success in astrophotography

Even the best optics can be used successfully only if the mechanics is right. Here, savings were often made in the wrong place. This is not the case for the Photoline 80 mm f/6 apo.

The advantages and features at a glimpse:

Rack-and-pinion focuser, plain bearing mounted. The support is decoupled from the drawtube drive.

Oversized drawtube with 60 mm clear aperture for full illumination even if full-frame sensors are used.

1:10 dual speed system for ultra-precise focusing

High-quality, sturdy CNC tube with internal baffling and very good internal blackening - no annoying stray light

M63x1 female thread on the draw tube, to get to the thread, 3 grub screws must be loosened

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

Retractable dew shield - only 37.5 cm transportation length

Modern and multi-coated 3-element lens with FPL53 as APO element

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

Each ring has 3 M6 threads (female) on top side, one of them in the middle, two in 30 mm distance at the side

Finder shoe is mounted

Visual use - spotting scope and astronomical travel telescope

The TLAPO804 can be configured with a star diagonal mirror, eyepiece and finder to form a lightweight telescope for travel, and a long-focus wide-angle eyepiece can be used instead of the finder.

If a 45° Amici prism is used instead of the star diagonal mirror, you get a spotting scope for landscape or bird watching. We recommend a zoom eyepiece, as it is more convenient and its field stop will usually not be larger than the clear aperture of the Amici prism, thus avoiding vignetting.

A tested combination of Amici prism and eyepiece on the one hand and tripod with tripod head on the other hand consists of the items TSA245 and HypZ as well as FGX3 and TSLH-20, which are all linked in the accessory recommendations. However, eyepieces with more focal length or true field of view can also be used, because the vignetting does not start abruptly.

Astrophotography with the TLAPO804:

The Photoline 80 mm f/6 apo is suitable for astrophotography without restrictions, but, as with any fast refractor, the field has to be corrected for keeping the stars nicely round even at the edge. For this, we offer the following options which are linked in the accessories section.

TSFlat25DEL - universal 2.5" field corrector without focal length change: The corrector is suitable for all sensors up to full frame format. The corrector will be screwed directly to the M68x1 connection thread. The working distance from the M48 connection thread to the camera sensor is 65 mm. If you are using a camera with 55 mm flange focal distance, such as an SLR with T-ring, you will also need a 10 mm M48 extension # TSVF210.

TSREDJM63S - 0.8x corrector for 80 mm f/6 triplet apos: The corrector offers a very good correction of the image field even up to full format, whereby we recommend a FLAT here. The working distance from the innermost position of the corrector to the sensor is 59.6 mm. If you have a flange focal distance of 55 mm, for example, then simply turn the helical out by 4.6 mm. The M68A-M63i adapter is required for adaptation.

No corrector: If you do not want to use a corrector, because for example the moon or (with front filter) the sun is the object, then you need, if also no star diagonal is to be used, in addition to the adapter to T2 or M48 still appropriate extension tubes. For ZWO planetary cameras like the ASI178MM you need for example:

TSFA2 (Adapter 2" to T2)

2x TST2V40 (give together 80 mm extension)

Alternative to TSFA2 and the two TST2V40: TSV280 (2" extension with 80 mm optical path)

Solar observation with the TLAPO80

The telescope is also suitable for solar observation. When using a front filter, the instructions for visual use or astrophotography apply, while when using a Herschel wedge for photography, it should be noted that 2" types may leave too little back focus. Omitting adapters when connecting the camera often helps here and replacing the regular adapter from M68 to 2" with a TSM68-2 adds approx. 8 mm to the supplied back focus.

The video in the "Reviews" section of the TSHE125, which was taken with this telescope, shows that a Herschel wedge is worthwhile.

Rosette Nebula with TL Apo 80/480mmField flattening with TS 2" Flattener© by Wolfi Ransburg

... more infos and max. resolution (in Germany)Only 125 min of integration time have been enough to capture this Nebula. Observation site: Munich east. Atmosphere: slightly foggy.FST: approx. 4m5.

 Telescope: TL APO 80/480mm-- Field flattening with TS 2" Flattener-- RGB channels by Baader RGB filter set-- CCD camera: ATIK 4000

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.
