Bob's Knobs for Meade 10" f/10 SCT with 6-Screw Secondary
Fits: All Meade 10" (25cm) f/10 SCT versions with six screws on the secondary housing. The inner screws are for collimation. It is important that you choose the correct style Bob's Knobs for your telescope. Please note the number and type of screws on your secondary housing before ordering. Meade has re-designed the secondary mirror assembly on their SCT's so that they have six screws instead of three screws that appear on the older design.
The three outer screws hold the secondary housing parts together, and the three inner screws are for collimation. The SCT six-screw secondary requires knobs with longer screws. Knobs for the 6-screw secondary must not be used on scopes with a 3-screw secondary. The screws are too long and they can contact the back of the secondary mirror.
