Hi Mark,
Thanks for your full explanations in Noob-speak. That was helpful on all the topics I was questioning.
Here are the pics of eyepiece as it exists with with pertinent ID and OD measurements:
Once the silver (chromed plastic) piece was removed, it appears to be around this 0.96 inch measurement you mentioned. No threads, smooth bore, 2 x ribbed thumb screws.
This means a converter (0.96 to 1.25), diagonal (1.25 to 1.25) and then 1.25 eyepieces? Is this the best combination to standardize?
I saw an AFOV of 48 deg on some of the eyepieces. I assume that is close enough to the 55 deg mentioned. I also saw some at 68 deg - better or un-suited?
Looks like some sets of eyepieces could be had that would cover the ranged mentioned and provide extra pieces. Some have Barlows, some have filters.

Here's an example of mirrored diagonal. I also see prism type. But I note they go into expensive range ($100's) very easily.

Maybe these two pieces would allow me to see if the rest of the telescope is functional, before buying a $100 eyepiece set?
I trust that the Plossl are sufficiently lowend enough to do the job for the quality of scope they are going in. I understand it to be a starter setup.
Anything to avoid? Can I under spend on these pieces and get a terrible image as a consequence?
Happy to hear that this is enough of a scope that it encouraged rather than discouraged your use.
Thanks again.
