TS-Optics 70 mm f/6.78 SD travel refractor for observation and astrophotography
The SD apo is an ideal travel telescope for all photographers. The telescope is very well corrected by the built-in corrector on the axis and in the field. In addition, the SD apo also offers a decent visual performance. Magnifications of up to approx. 150x are well handled by the lens, the chromatic error is significantly reduced. We recommend the telescope for all photographers who are looking for a portable, inexpensive and yet well corrected refractor for photography and observation. Since the corrector is built into the tube, the costly adapter battle is no longer necessary. Simply focus and you are automatically at the optimal distance.The connection of accessories:
The TSED70Q has a very comfortable working distance of 135 mm from the 2" receptacle, so you can use 2" star diagonal mirrors and eyepieces and you can focus with ease.To connect a camera, we recommend the adapter TSFA240, this adapter has 40 mm length and a T2 thread on the camera side. With this adapter you can connect all common DSLR, system or astro cameras. In addition, the focuser has an M54x0.75 female thread for screwed adapters.

Test report of the TSED70QWe have tested the TSED70Q extensively and are very satisfied with the optical performance.
The telescope is also convincing on the outside: The apo is an absolute lightweight with 3.8 kg, but at the same time makes a very solid impression.
The focuser is decisive for every clean shot. The TSED70Q is equipped with a 2.5" rack and pinion focuser. Here nothing wobbles. The focus position remained absolutely stable after the obligatory cooling time.
The built-in 2-element corrector sits in the tube. So the often annoying exact achieving of a working distance is no longer necessary. You only have to come into focus. This can be done, for example, using the 21 mm T2, and 16.5 mm T2-M48 adapter included in the scope of delivery of cooled ZWO cameras.
IC2118, the Witch Head Nebula, served as the object. The camera used was a ZWO ASI071 at Gain 90. Due to the short focal length of the TSED70Q and the relatively large sensor of the camera we got a field large enough for this extended object.
Despite the relatively short exposure time of 2.5 h and the weak brightness of this object (Mag 13), we could already resolve many details. Also the color in the structures already shows up well.

"In der Beschreibung des TSED70Q-X Quadruplet 70mm ist die Angabe ""SD Objektiv"" nicht richtig. Sollte natürlich ""ED Objektiv"" sein. "

"Qualitativ ist das als Astrograph ausgelegte Teleskop ein sehr überzeugendes Produkt. Es sieht sehr wertig verarbeitet aus und wird zudem in einem Transportkoffer geliefert. Die Montage von Zubehör, wie Sucher oder DSLR-Kamera ist mit entsprechenden Adaptern problemlos möglich. Ich empfehle die Verwendung einer 2? Kamerahalterung, da diese in dem drehbaren Okularhalter gleich von drei Rändelschrauben fixiert werden kann. Die Fokussierung der montierten Kamera geht mit dem verbauten Okularauszug erstaunlich einfach und liefert dank des eingebauten Flatteners ein sehr gleichmäßiges Bild. Daran erkennt man, dass dieses Teleskop in erster Linie für Fotografie ausgelegt ist (auch für Terrestrische). Für die visuelle Beobachtung muss man dafür ein wenig herumtricksen. Der etwas billig wirkende 2? auf 1,25? Okularadapter ist in Verbindung mit 1,25? Okularen völlig unbrauchbar, da man schlichtweg nicht in den Fokus kommt. Es fehlen jeweils 5-10mm Hubweg am Okularauszug, egal ob mit, oder ohne Zenitprisma. Einzig die Verwendung eines kompakter (flacher) gebauten Okularadapters in Verbindung mit einem Zenitprisma lässt eine erfolgreiche Fokussierung zu. Dem Teleskop hätte gleich ein passender Adapter beigelegt werden können. Dies schmälert jedoch nicht meine Begeisterung über dieses kompakte und handliche Instrument und ich kann es als ein Allround-Teleskop zu dem sensationellen Preis nur wärmstens Empfehlen."
