  The M68-OAG is suitable for full frame camera. The ordinary OAG is suitable for 294MM Pro.

How far does the guide camera helical protrude on the telescope side of the OAG? I need to ensure sufficient space for my rotator.

How are the ZWO M68 OAG and the ZWO M54 Filter Drawer able to be connected to each other. Are the required parts included with either of these products or is an additional adapter required? Thanks in advance.

I purchased the ASI 174mm for a guide cam.

Also I am considering the M68 OAG, but the ZWO prism size is 8mm x 8mm.
The ASI 174mm sensor size is 11.3 mm x 7.1 mm, so I think the prism size is a little smaller than the sensor size. I ask for your advice on this.

And when will additional M48 TILT adapters be released?

Bonjour,
J’au acheté une ASI6200, EFW et OAG et camera 120 mini. Mon probleme est que le capteur de la 120 Mini reste trop loin du trou de l’OAG et je ne peux pas faire la mise au point. Avez vous une solution ?

Noah – February 12, 2021:

Hi, does the M68 OAG suit for the ASI294 and 290 for guiding? Is size and adaption to full frame cameras the only difference or does it not fit for small cameras or some telescope types?
