I considered upgrading the stock focuser, and still may go that route.


For now, I shimmed it up a bit and it's much tighter and smoother...and a bit of bling too

A few upgrades for the stock secondary mirror.

Added a teflon 'slip ring' to allow the mirror to rotate smoothly when collimating. Also installed a thin stainless washer where the adjustment screws contact the aluminum base for the secondary. It developed small dimples over the years, and collimation was getting difficult as the little dips sucked the screws into the same place.
