Laser test..
Meade FR groups configuration based on reflections from surfaces is now consistent with data sheet (Thick-Thin, gap, Thick-Thin).. but not with simulation..
Celestron configuration is not so obvious (probably due to different glass and coating applied), but with some effort it appears similar and closer to simulation model.
They are not optically identical design, that is for sure.
