Have Meade Lx200 8"
Contemplating a focal reducer.
I see several options:
Celestron f6.3 - $300
Meade f6.3 - $232
Un-named brand - $110 from local supplier
Does anyone know if these will all fit my Lx200 ? (ie. are the Meade/Celestron models interchangeable?)
Any opinions about the relative visual quality of these options ?
