Anyone got any suggestions on where I can find some advice on pulling apart a Vixen GPD2 mount.
I had session on saturday night,and the darn Declination started playing up,and appeared to 'stick' The first couple of hours everything seemed ok,with 3 and 5 minute subs.Then it all went to poo. We did a drift alignment.
The mount is on a pier in observatory,it appeared all was well P.A'ed. But as the evening went on that dec still went bad.So ended up turning it of and just used R.A all the 3 minute subs were all very passable and usable though.
But there is an issue,so we need to strip it down,and give its insides a good clean,and tune and grease (any recommendations).
Being in an observatory,maybe dust has got in,or some rust inside it.
Thanks for any thoughts or help.
