Description
Fine focuser add-on for standard Celestron rack and pinion focuser
Provides 4:1 reduction for fine control on the focuser
Easily reversible, no permanent changes, take it off if you dont like it
Takes up one side, leaving the other side knob as is for coarse control
Thoroughly tested
Why I made this
We got a new telescope (Celestron with a standard 1.25" rack and pinion focuser) and the focuser was super jumpy.
I first removed the insane gummy grease in the rack and pinion and put some decent grease. Was still unhappy, looked at getting a 10:1 focuser, but that would be more than 50% of the cost of the telescope
This is a retrofit, which doesnt even need additional screws
