The more popular chatGPT need to register phone number so I tried this alternative ChatSonic.
Here are the results.
AI pick a 4inch refractor

Tried to add "Singapore"
Nope , don't get the PS127 it is spherical+small-glass-corrector not the proper parabolic curvature mirror
Paying for google ads helped to make the AI select it into the answer , since ChatSonic is influenced by google results.

Good answer about portability.

Good answer.



Overwhelmed , I think library , youtube , google search are better answer.
