I have a meade 4400 114mm 910mm 4.5 f/8.. I have upgraded the eps holder to a 1.25 from a 0.965. I read that upgrading my focuser from the stock focuser would be the best upgrade to do other then the eps. My Question is would it be worth my time and money to invest in a moderately priced focuser that might not have the slight backlash in the rack and pinion will it help at all in focusing please share your thoughts. and clear skys
replacing focuser ??

Hi Albert...
Personally i would probably wait a while to replace the focuser. It's not such an easy task since it is unlikely that you will be able to find a direct replacement focuser that just bolts right up without modifying the your telescope. This means drilling holes and maybe enlarging the exiting hole for the focuser itself. If you don't get things in quite the right place or aligned properly then there are more problems.
In my experience, the plastic focusers are adequate though not perfect but in an F8 Newtonian, focusing is quite forgiving.
