No, Kevin. I can't. To get focus with Canon I needed to cut 35 mm of the OTA.
Today, with the configuration that you saw, the focuser is away about 20 mm. This is only the wheel.

And, warnning, my coma corrector is a GSO and it has a barlow behavior of 1.14x. I don't get focus with only Canon and OAG. Because of the OAG and adaptors.

I tryed to put only the OAG in front of Coma corrector, but with the adaptors needed, is the same. I have more than 20 mm. I don't get focus.

The solution is very easy: cut more 10 mm of the OTA. This issue is new to me. Using only the skyglow filter, I put it before the coma corrector. So, the reflex doesn't occurs.

And, attention, I changed the adaptor Canon-T2 (10 mm) by Canon-M42 (1 mm).

With the Canon-T2 the reflex is very worse and different. The total distance was 93 mm. See the photos. The star is Cannopus. Photo 1 with skyglow filter. Photo 2 with Halfa filter.

The great problem is only one: Canon ! His sensor is very deep, inside the body of the camera.

The fatal problem is only one: money ! I haven't money to buy a good mono camera.
