Vortex Gen1 85 spotting scope adaptor for 1.25" astro lenses

[FredinBoise]

APM telescopes makes a bayonet mount that fits the Gen1 85mm scope as if it were factory. $40 at https://www.apm-telescopes.net/en/apm-spottingscope-adapter-125- This allows the use of many 1.25" astro lenses and there are all kinds to play with. Not all work but if the focal stop is below the shoulder of the eyepiece, it will work.

Celestron X-cel lenses are reasonably priced, good quality and work just fine.
