Do I need to buy a new focuser, or does anyone know where I can get the replacement wheels?
If I need a new focuser, can you please suggest which one I should get? I don't need anything advanced since I use ZWO EAF to focus.
Thank you

Hi Daniel,
IF all that is broken are the wheels (Ball Bearings) then a bearing supplier should be able to source replacements for you. Look for make and bearing numbers on the sides of the bearing races and/or take them in to your local bearing supplier and they should be able to provide a replacement. Fortunately there are many bearing suppliers in the Melbourne South East, Moorabbin, Clayton, Oakleigh. If you search Bearings in Moorabbin that should point you in the right direction.
ALSO Check carefully that it is only the bearings that are damaged and not the abutting rolling surface or any bearing holders, mounts. threads etc...
Best
