OAG setup

[Ronclarke]

I'm starting to use this OAG to keep the weight down on my Adventurer mount at Kelling next month.

Does this image train look correct?

Comments please...

Do you get stars in focus on the guide camera?  I ask because I would expect the distance from the OAG prism to image camera sensor to be the same as the OAG prism to guide camera sensor and it looks as though this might not be the case?

Other point (and it may be the angle that the photo is taken at): is the guide camera square in the OAG holder?  Only it looks tilted to the left in the lower image.
