made it so easy to start again with astro photography after nearly 20 years - so much changed, particularly the available technology

Using a SVBONY SV106 Guide Scope I'm able to do PA. I'm mounting this guide scope only for that reason and after PA I remove it.
My main equipment is a LX200R 8" with a ZWO ASI585MC, OAG & a 120MM Mini. Would be great to do PA only with that.
With the main gear I'm always able to do a tools -> plate solve, and in PA mode it identifies enough stars. Data acquisition and the possibility to solve the position in general seems not to be the problem, see also two attachments. I understand that as my FOV of 0.32 x 0.18 is much small than the required FOV it's not working.
I was wondering if there is a way to make polar alignment possible for smaller FOVs. Either by adapting the algorithms in sharpcap or by having the possibility to load a more detailed set of stars for polar alignment with a smaller FOV. or would this have a huge impact on the accuracy?
If you introduce this, maybe in experimental mode or a special build, I can offer to try it out

Thanks,
