Quote:The manual says it has a c mount adapter too. Ordered.
Quote:I picked up one from the local office. It comes with a Canon and T ring adapter for the sensor end. Overall thickness of the assembly is 13mm. They use a special ring with "ears" that's recessed past the mirror. This ring allows slight rotation of the assembly - maybe 45 degrees. The pick off mirror can be moved sideways a little bit, too. The recessed ring and the mirror can be secured by two thumb screws. This seems to reduce chance of flexure.
Quote:I put the Canon adapter in place and measured it with my depth gauge and show 19.22 mm. This is measured from one side to the end of the flange bayonet. There might be a slight protrusion beyond the standard depth because of the thickness of the metal part. As best I can measure to the flange surface (the face of the bayonet) it shows 15.00 mm.

Quote:Yes, the M48 to T thread adapter on the telescope side of the OAG does add some thickness. It appears to be about 2.5mm. I don't have a lens spanner wrench, so I can't remove it to measure more directly. If you had a system that could use that thread size, then you'd be able to reduce the length accordingly.

Quote:Your welcome! The guider is 10.5mm in width. The Canon adapter adds a little. That shoulder is part of the adapter not the TOAG body if that helps.
I was using the Tele Vue Wide T-adapter, (http://www.telescope.com/Tele-Vue-Canon-Wide-T-Adapter/p/8849.uts?keyword=canon) and they are within ~1 mm of each other in width.
Quote:This is good news! I think I'm now sold on this.Any chance of another close up edge on pic like above, but showing the T-2 thread adapter installed into the 44 mm threads?
Quote:Can anyone tell me how wide the 'coma corrector' spacer is? I need like 5mm in my image train and I'm hoping that works.
