The latest innovation from Bob’s Knobs is a set of tool-free collimation knobs for Meade’s LightBridge telescopes. Starting at $45 for a complete set, the primary- and secondary- mirror knobs replace the screws supplied on Meade’s 8-, 10-, and 12-inch models. Also available are replacement primary-mirror springs for $16; these are stronger than the factory versions and won’t sag under the weight of the mirror cell. When ordering, please specify which LightBridge telescope you own.
