TS-Optics 80 mm f/7 ED APO refractor for astrophotography and observation
The refractor is suitable for both ambitious beginners and experienced astrophotographers. The telescope impresses with its well-corrected optics and excellent mechanics. The tube weighs less than 3 kg. It can also be mounted on smaller mounts and stable photo tripods.

The 2-element ED objective:
An S-FPL51-ED element minimizes chromatic aberration and ensures high-contrast, color-neutral images. The lens is supplied in a temperature-compensated cell. Multi-coating on every glass-air surface allows for high contrast during both daytime and nighttime observations.

Astrophotography with the 80 mm f/7 ED:
The precise focuser and fast optics make the 80 mm ED refractor a good telescope for astrophotography. To correct the image field, we recommend the following correctors - these are also linked in the accessories section. The correctors are screwed to the focuser using the TSM54A-M63i adapter. This prevents them from tilting.
TSFL80F7-2E ... The 1.0x corrector provides a flat image field and does not change the focal length. The working distance from the M48 thread is 55 mm. The corrector also offers an intermediate thread for 2" filters.
TSRED80F7-2E ... The 0.8x corrector reduces the focal length to 448 mm and improves the focal ratio to f/5.6. The working distance from the M48 thread is 55 mm. The corrector also offers an intermediate thread for 2" filters.

"I am using it mainly for astrophotography with DSLR. Although I do not have field flattener (I have APS-C size censor) it does the job well enough. VOF is large enough that I usually can crop edges away. without losing the target. Telescope seems to be good for those who are looking decent and not too expensive refractor for more or less sporadic use. Built quality seems to be very good. Much better I expected in this price range. Telescopes (also OTAs) should always come with some basic indrotudtion papers how to use the telescope. Like what is which screw etc. I tried to find information how to change the hand of focure (from right to left) but I could not find any even from your site and I did not wanted to start quessing how I dismantle the focuser. However, while examinating this I found some scratches on the focuser bar. It seems that somebody has tried to focus the telescope while the focusing lock screw was tightened. That focuser lock screw is probably the weakest point of this telescope."

"Ich verwende den Refraktor vorwiegend zur Beobachtung des Mondes, der Sonne, der Planeten Jupiter und Saturn sowie für Übersichtsbeobachtungen von helleren und größeren ausgedehnten Deep-Sky-Objekten (Plejaden, Orionnebel, Andromedagalaxie). Gegenüber der Beobachtung mit einem Achromaten erkennt man im Vergleich ein deutlich farbreineres, kontrastreicheres und helleres Bild. Fotografische Aufnahmen sind angedacht, wurden aber noch nicht umgesetzt."

"Ein gutes Refraktor mit guter, sauber abbildenen Optik. Die Anwendung kann sehr breit sein. "

Excellent scope with a solid feel to everything, if you are a complete beginner get good advise on how to set it up as it can suffer from back focus, especially with some accessories. Otherwise no grumbles.

"Quality build and finish, the focuser is particularly good with a nice smooth action. Lovely views, great for sweeping the sky and makes a very convenient ""grab and go"" scope."

"Trotz der kleinen Blende ist das Instrument nahezu farbrein in der Abbildung mit scharfen Sternen bis zum Buldrand. Mit einer 2fach Barlow Linse ergibt sich eine ideale Brennweite für Mondaufnahmen bei APS-Sensoren. Technisch und haptisch ist das Teleskop ebenfalls ausgezeichnet. "

"Preisleistungsverhältnis top. Farbreine Darstellung. Vom Gewicht her mache ich damit noch Aufnahmen mit einer Skywatcher Staradventurer Montierung. Wertiges Material. Einziger ""Kritikpunkt"": man könnte eine längere Prismenschiene mitliefern."
