  • The entire optical path of the TSOAG11 and the Canon EOS camera is exactly 55 mm.
  • Connecting thread on the telescopic side: M48x0.75 female thread. The thread can be reduced to T2 with an optional ring.
  • Camera side connector: Canon EOS bayonet.
  • The off-axis guider is APS-C and full-frame. 
  • Fits perfectly on all standard corrector and focal length reduction systems , which work with 55 mm distance.
  • Easy adaptation to other systems possible
  • Easy focus of the side focus for the autoguider by shifting the T2 connector

TS Optics off-axis guider for Canon EOS cameras

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

Thus, the TSOAG11 takes over the task of T2 or T-ring and also offers the possibility 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 optimum distance.

How does the TSOAG11 work:

A small prism dazzles a bundle of light close to the edge of the beam path. The prism is positioned so that it does not cause shading. The stars, which are in this light bundle, can be used for tracking. There is a field with about 7 mm diameter available. So you will always find a beacon with the matching autoguider. The special structure of the Off-Axis Guider allows only one camera position.

The position of the lateral view is directed exactly towards the bottom of the camera. That is also desired, because so the position of the small mirror is set exactly so that there is no vignetting. The camera sensor is fully illuminated. Up to a light intensity of F / 3,8 we can guarantee the full illumination. To mount the off-axis guider, the side T2 adapter must be removed.

Working with the TSOAG11 is easy. Set the desired object in the viewfinder of the Canon DSLR camera. Check the sharpness setting on the focuser and prepare for shooting. Then check if your autoguider already shows a beacon. As a rule, even several will be available for selection.

The condition is, of course, that the sharpness of the autoguiding focus is aligned. A brief guide to this can be found in "Reviews". Then prepare the autoguiding process and start recording.

Left a scar on my DSLR, doesn't quite fit with 1100D

I use modded Canon 1100D for Astrophotography. I purchased this OAG as I use TS-Optics Photoline 72mm APO F6. You just can't simply attach 1100D without applying force as the OAG is in the way on locking the camera body to this OAG. It eventually left 1mm depth of scar on my 1100D camera body. I am so surprised that TS Optics is selling this item without testing on all avilable Canon cameras. So disappointed.
