I wanted a a bit more magnification for my Davis Mk25 so I fitted a cheap 8x20 prismatic monocular. It fits on the mounting bracket with no modification as the objective lense tube unscrews. It locates in the front telescope bracket as it is conical, and the prism holder fits flush against the rear bracket when tightened. It gives a nice clear view and is certainly easier for me to to take sun sights with an artifical horizon while on lockdown at home (and my Tamaya is on the boat).
There are a few more photos on my Blog entry https://tuioyster.blogspot.com/2020/05/fitting-prismatic-telescope-to-davis.html
