play/slack in ioptron-E 8500 causing jittery tracking?

#1

Post by realflow100 »


if I dont slew my telescope around for a while in all directions for a minute the tracking is quite jittery and stair-steppy. and theres almost half a FOV worth of play/slack in the left and right and up and down movement if I wiggle it by hand
up and down isn't as much of a problem as left to right since my camera acts as a weight keeping it somewhat consistent vertically but if I bump it with my hand too much it will rotate left and right about half of the telescopes FOV!

Is it possible to tighten something internally to reduce the slack/play?

Also the clutch will sometimes self-loosen and my camera will SLAM HARD into the tripod leg of the mount. How can I better tighten the clutch? the best i can do is turn the knob as tight as I can while angling the telescope downwards to get it extra tight so it wont loosen itself.
Also its quite noisy. an obvious electronic motor-noise PWM sounding hum to it when tracking. at 256x or MAX its quite loud (not scary loud. but close to idle conversation volume) at 2x 8x and 64x its mostly quiet.
is it possible the gearing wasnt greased/lubricated properly? should I worry about that?

could the gears just be not meshing snugly enough? too much play in the gears meshing and stuff?
