Umm...sure.

Actually it's all dissasembled so no, no more pictures - sorry. I used this for off-axis guiding with an SBIG ST-ic which uses a Kodak KAI-340 CCD, but I only needed a star to do that and I was able to move the prism anywhere around 100 degrees within the image. But, I do know what you mean about reflections and apologies that I can't show you imaged from the OAG, I did not have any problems when using it.
I used it in an image train that was t-thread all the way through, that's 42mm (I think) and my sensor was APS-C (a Sony ICX413 in a QHY10 OSC).
