TS OAG off-axis guider for Canon EOS camera instead of the T-ring bayonet adapter

The off-axis guider is integrated in the T-ring and does not require any additional path. Ideal solution for astrophotography with Canon EOS DSLR cameras.

♦ The off-axis guider is the same length as a T-ring for Canon EOS cameras - 11 mm

♦ The total optical path of the TSOAG11 and the Canon EOS camera is exactly 55mm

♦ Connection thread on the telescope side: M48x0.75 internal thread. The thread can be reduced to T2 with an optional ring

♦ Connection on the camera side: Canon EOS bayonet

♦ The off-axis guider is designed for APS-C and full format

♦ Fits perfectly on all common corrector and focal length reduction systems that work with a distance of 55 mm. Easy adaptation to other systems possible

♦ Easily adjust the side focus for the autoguider by moving the T2 port


 
TS Optics Off-Axis Guider for Canon EOS cameras
This off-axis guider is specially designed for Canon EOS DSLR cameras and offers an optimized distance of exactly 55 mm including the camera from the M48 thread connection. With the optional adapter ring TST2-M48S (see accessories recommendation) the thread connection can be reduced from M48 to T2.

The TSOAG11 thus takes over the task of the T2 or T-ring and also offers the option of tracking with an autoguider. The TSOAG11 has exactly the same length as a T-ring, namely 11 mm. You can simply replace your T2 ring with the TSOAG11 and automatically have the optimal distance.
 
How does the TSOAG11 work:

A small prism blocks a beam of light near the edge from the beam path. The prism is positioned so that it does not cause any shadowing. The stars that are in this bundle of light can be used for tracking. A field with a diameter of approximately 7 mm is available. So with the right autoguider you will always find a guide star.


The special design of the off-axis guider only allows one camera position. The position of the side view is directed exactly towards the bottom of the camera. This is also desired, because the position of the small mirror is set exactly so that there is no vignetting. The camera sensor is fully illuminated. We can guarantee full illumination up to a light intensity of F/3.8. In order to mount the off-axis guider, the side T2 adapter must be removed.

Das Arbeiten mit dem TSOAG11 ist einfach. Stellen Sie das gewünschte Objekt im Sucher der Canon DSLR-Kamera ein. Überprüfen Sie die Schärfeeinstellung am Okularauszug und bereiten Sie die Aufnahme vor. Dann checken Sie, ob Ihr Autoguider bereits einen Leitstern zeigt. In der Regel werden sogar mehrere zur Auswahl stehen.

Die Voraussetzung ist natürlich, daß die Schärfe des Autoguiding-Fokus angeglichen ist. Eine kurze Anleitung hierfür finden Sie unter "Erfahrungsberichte". Bereiten Sie dann den Autoguidingprozess vor und starten Sie die Aufnahme.
