TheLivster The #494 is NOT user update-able. Even using the #506 serial cable (not easily made,

unlike the #505 serial cable for the #497 AutoStar) won't let you install a fresh copy of the software. With the

cable you MIGHT be able to force a RESET of the AutoStar, which MIGHT clear the error (but probably

not). Since the Proc Trap 2 error occurred after a battery change, I would suggest checking the batteries; are

they all inserted correctly? If so, try different batteries. If you can get to the menu item, be certain to do a

CALIBRATE MOTOR.

I own an ETX-90EC and really enjoy this scope until the recent horizontal movement failure. I dissembled the scope tube

from the arms and found the movement post end (Plastic) had worn away as well as the gear end post (plastic as well).

The worm gear is fine and rotates the gear post but the connection has worn away Is there somewhere to obtain these

parts? If there is I can't find it on-line. Please help ... I would love to be able to use the scope like it should be used.

WBeckerson You might try Telescope Warehouse (link on the Astronomy Links page). You might

have to buy a complete base.

Thanks for the advice. Yep I've tried it with the external battery lead and another external power supply, and checked

polarities. Putting the multi-meter on the internal pins doesn't show any voltage on the red or blacks where it logically

should be, so I tended to think that there may be a broken trace or the switch may be stuck open. The person I bought it

from had it from new and never used the handset or autostar, just aimed it manually, and not much of that either. I may do

a bit more rummaging around with the meter on the little board before I get violent with it.

Actually I lie...I've just re-read /etx/techtips/2004/batterywires.html where dr Clay mentions that it's a glue and press in

and can't be removed, which seems damn silly from a maintenance viewpoint, but what can you do?? I'd still be interested

in anyone's experience in breaking it free.
