I just purchased an EQ6-R Pro (like...an hour ago ) as it's the platform I'll be building my DSO rig around. I'll be taking baby steps with my gear, and starting by using my Nikon D7100 and a 200mm F/2.4 lens. The step after that will be a guide scope and camera, then I'll grab a better telescope to replace the 200mm camera lens, and finally I'll get a dedicated astro camera (likely a ZWO something).
My current problem is trying to figure out how to attach my DSLR to the mount in such a way that would allow for a guide scope to be used as well. The current thought is to use something like this: https://www.admacces...-small-version/ or maybe even this: https://www.admacces...connecting-bar/
The problem with the above solutions is that (as far as I can tell) this would position the camera (and eventual scope) 90-degrees off of where I'd guess I would want them to be.
Does anyone know if it's possible to somehow tell the mount that the lenses are positioned at 90-degrees?
If I understand your question correctly, you're asking if you can mount your cameras aimed 90 degrees to the long axis of the dovetail saddle and still have the mount function properly.
Both of the axis have clutches that allow them to rotate freely. You release them to balance your scope. Before you polar align and star align the mount, you firmly lock down both clutches. The mount doesn't care how that saddle is positioned when you lock it down. The dovetail saddle can be at any angle, just don't release it after you align.
Did I get the question right?
