Thanks guys.
I have a Moonlite focuser with high res stepper which will carry 8 pounds, according to the specs, so a bigger wheel should be ok, just don't have the money for it at the moment, so I'm trying to cover as much ground as possible with what I have already.
Im only using a 110mm scope, so at the moment, I don't do galaxies. When I move to a bigger scope, I might change filter wheels.
