New Moonlite Focuser

I'm replacing the stock 2 speed focuser with a new Moonlite Dual Rate Tri-Knob focuser with the 1.75" compression ring draw tube.

The stock focuser was a little sticky even after doing the GSO tune up from some very good, detailed instructions on polluxchung website.

The new Moonlite focuser is very smooth and buttery.  I can turn the knob to focus without the sticky click from the stock focuser.

Stock focuser.


Side by side comparison.


First attach the curved mounting plate to the tube by matching the existing holes to the hole patterns in the base plate.  I used the provided screws to attach the base from inside the tube.


From the universal install kit I chose the 1/2" and 1/4" spacers for the correct height.



3 sets of different length screws are provided.  Find the correct length and attach the fosuser to the mounts.



Collimate and it's done!





The new focuser ready for night!
