A lot more possibilities for adaptions you can see here (especially the last page for the video modules):
You need to bring the camera sensor and the field stop/image plane of the eyepiece into the same distance from the FlipMirror.
For a 2" eyepiece, you can use
#2956242 M42i x 0.75-ClickLock (Astro T-2 System) - 36,6mm long
plus a 1.25"-adapter like
Baader 2" to 1¼" ClickLock Reducer (T-2 part #15B) # 2956214 - 9.5mm long
Baader Pushfix Reducer 2" to 1¼" (T-2 part #15a) # 2408151 - 1mm long
But we usually recommend a 1.25" focussing eypiece clamp instead, to do some fine adjusting between camera and eyepiece. Or you can use a clamping ring to set one eyepiece to the same focus as the camera. Usually, the focus position of several eyepieces is slightly different.
I can't find the backfocus of your camera to determine how many T-2-extensions you need for the camera.
Please take a look at this article about determining the correct distances:
