The standard rack and pinion focuser on the skywatchers is just that snot! but the one thats on my 10" is fine. sure it flips around abit but hey its standard kit.! for people who cant afford to go out and purchase 150-200 dollar focuser modifying the ring to fit is perfect if you can do it yourself, its free if not get somebody to do it for you and it shouldn't cost you much at all aka 30 odd should see it done.
Ive had no problems with the skywatcher crayford focuser to date, though i will be upgrading it will be for precision reasons and in anycase im going to build one myself an external crayford type. Its just lucky im hanging around engineering type people (being a engineer myself
) especially those in Mechatronics so i have spoken already and a friend of mine is going to be writing a ascom compatable driver for a PWM motor, virutally giving me a computer controlled motor... easy as.
