In a previous post I mentioned that I purchased a new illuminated Meade 9mm eyepiece with XY adjustment screws.
I used this new eyepiece on my CCDSPEC spectrometer on my Sky Watcher Equinox Pro 80mm telescope during my observing session 26/5/2019.
Itwas fantastic! When I ensured the star remained in the little illuminated central square as I hand-guided, every time I successfully obtained a spectrum of a star. More problematic with M57 The Ring Nebula but this was due to this objects relative faintness and difficulty of swing it at all with any time finder eyepiece in CCDSPEC. That is something I need to find a solution to.
