Astronomik Clip-Filter for the mirrorless full format cameras EOS R and RP
The new clip filters can be used with all lenses on the camera body without any modifications.
The clip filters are optimized for use with normal camera lenses and telescopes.
All Astronomik filters are now also available as Clip filters EOS R!
The Astronomik CLS-CCD is our advice as an ideal “all-round filter”: The CLS-CCD largely suppresses artificial light pollution and enables deep, long-exposures even from locations with strong light pollution while giving your natural colors!
Beside the CLS-CCD the Astronomik emission-line filters H-alpha, SII and OIII with 12nm and 6nm FWHM are available.
The Astronomik ProPlanet 642 BP, 742 and 807 give the infrared photographer a wide range of filters at his disposal. The UV+IR blockers L-1, L-2 and L-3 complete the family.

But if you use the body directly on telescope there is no use/need of an adaptor.
And these filters are designed for that purpose: body + telescope
And - of course - directly with RF lenses ;)
But they are all different, and they are just filters. This is just a Form factor, so they can do what ever you want. The article above mentions a UV and IR blocking filter, I guess that is indeed meant to make a full spectrum modified model more usable for regular photography.
