Otherwise, a splash of matt black will do the trick, but even then I would only do it if you can see light scattering on bright objects. Just be careful transporting your OTA with that shard of glass rolling about inside

I agree, if you think about it logically there has to be safety built in for when people DO go at things heavy handed, and also when focus motors are fitted there are (as I found by contacting Celestron and asking) HARD stops at each end of travel so this will not happen, either you turned it with more force than should be expected or as said here there is another reason
