Hi,



I'll start with the apology....so sorry all, but my compliments--you

were all correct at one point or another, and I included a cut and paste

error in my original post which further confused things. Here is the

story in short (abridged) form:



First clue is that this happened on Christmas--that comes with

visitors--tipsy visitors with curiosity and roving fingers that pick up

and fiddle with everything. And I hadn't slept in 20 hours or so. I

had just serviced the telescope mirrors which were cleaned and a minor

secondary issue was repaired. The mount was fired up, data entries

double checked, the telescope was leveled and set at park 1, and I told

the visitors not to touch anything (while they were left unattended in

the observatory).



Return to the house control position, fire up the computer, and get SkyX

sync'd up with the mount--aok (not so fast). Did a simple test goto to

polaris--close, but not as good as usual--return to park 1....mount went

right through park 1 and ended up with weights up.



So I stopped and manually reset everything and repeated the process,

slewing to M42--ended up way short of target--return to park 1, the

mount stopped short of park 1 with scope-up. At one point, SkyX was

indicating wrong side of the pier.



Then I got sucked into the trouble shooting, which generated the posts.



After interrogating my visitors, I realized that after watching me do

the manual setup, one of the visitors was fiddling with the handbox (two

times) while I was returning to the control desk -- so when I

initialized SkyX, I captured an incorrect position.........and the

adventure unfolded from there.



I was visitor free last night and was able to straighten this out--so

the mount is fine and somehow I did not have a pier crash--I am stunned

with how my allegedly mature visitors completely miss the point of my

asking they not mess with stuff. They are yet another reminder of where

the bizarre "don't do this/that" signs in public places come from.



I appreciate the efforts of those who responded and I will add handcuffs

and hog ties to my bag o' tools...and possibly replace my friends. I'll

also add "no visitors" and "do not dispose of used diapers in the

telescope" signs.

You can just unplug the keypad. Don't worry, it can be done with power on, and the keypad will remember where it was when you plug it in again - with power on. That way the only thing they can do easily is to remove the safety stop on the counterweight shaft, and then loosen one of the 18 pounders, which will slip off and crash thru the concrete, narrowly missing two sets of toes. Rolando
