I'm intrigued by tiny refractors and after learning the Mini Borg 50mm no longer is offered, I'm looking for alternatives. If I wanted to try the Skywatcher 50mm Evoguide for visual, would I just need a diagonal? Yes, I know it's small and no, I won't do any imaging.

The problem is that the 50mm Evoguide doesn't reach focus with a diagonal...

 

 

Clear skies!

You may find these previous discussions helpful:

TL;DR: it can be done, but only straight-through or with a right-angle diagonal (no RACI). Eyepieces that require more inward focus travel may not work.

 

If you are willing to cut the OTA (or can remount the optics in a shorter tube) then any diagonal/eyepiece combination should work.

 

If you do not insist on ED glass, you can try a high-quality 50mm finder:

Is the SharpStar 61EDPH too big for you?
