Nikon/Canon to zwo adapter with off axis guider possibility

benni

Hi, I would want to use modern telephoto lenses easily with the asi.

Currently, for using e.g. a 300 2,8, which is an excellent lens for astrophotography, one needs to use a guiding scope. (And in order to align the mount, a viewfinder....)

Some off axis guiders only have 9mm thickness.

Is it possible to make a ZWO to Canon/Nikon Adapter with an off axis guider included? Or do these lenses not have a large enough image circle that they would throw light onto the prism?

Hi there

I think it is not possible, because the diameter of last len of DSLR lens is to small, and aperture also will reduce the diameter of light path.

So the OAG is hard to get light and find stars.
