One Time Magnification Eyepeice
Hello. Most eyepieces I find are usually 10 times or 25 times. Is there a way to get one that has no magnification and only gets in focus whatever is coming out of the objective. I would like to know if this exists.

No, not for viewing anyway. It would be totally unusable. There are 1x focal eyepieces for goingg direct onto a camera sensor but they aren't usable to the eye.
Re: One Time Magnification Eyepeice
If you set-up a camera lens [or even something simpler] to give 1:1 reproduction, then it would relay the primary image from its plane to somewhere beyond the tube … and also invert it.
You could then observe this on a small screen … but I doubt it would be particularly useful.

This might serve as a useful optics ‘refresher’ : https://g3ynh.info/photography/articles/opt_mag.html

Too many 'projects'

If you want to look at larger items on the stage then there are some new Chinese 1x and 2x objectives on ebay.....this isnt a recomendation
( eyepieces can be bought at 5x....old ones seemed to be 6x ).

Microscopes have became more 'trapped' over time ..but with older stands (think drawtube /horseshoe stand) it is quite possible to get wider fields of view:
Poor phone pics, through the eyepiece, but just to give a sense of what you can get: [On the objective changer of a Watson Service, I think ]
Indeed that was a purpose for the RMS thread at the bottom end of a drawtube
Or indeed this...not the right objective ..it is a DIN objective ..stretched on the rack..as it were:
