Being insecure and all, I really want to have an option to flip to EP from time to time to verify that the guider is looking at the intended star.
So I sourced an Orion Flip Mirror from Optcorp.com
The device is M42 thread all round and hence very flexible in how one mix and match.
However, just one problem, with the guilder as straight through, the focal plane falls nearer than the EP could be (by about 1cm).
Thankfully, I managed to source a M42 spacer from scopestuff
The EP holder of the flip mirror has an inline par-focal adjuster. Now I just need to calibrate it once and I will not have to fiddle with it in the future.
