Have an interesting issues with my 1200GTO.  After thetelescope sitting parked in the observatory for a period of time, say severalweeks on startup it is completely lost.  I am running ASCOM driver, TheSky 5.xx, ACP, Focusmax, MaximDl.  The system is running  mounted inan observatory, the hand pad is NOT connected.  The system runs all night,ACP will park the scope at the end of the run.  Telescope is pointed aboutto the zenith when parked.  I will need to reconnect The Sky so I can usethe ASCOM AP driver to move the scope so the roof will clear the scope to closeroof.  Then the scope is reparked at the zenith position.  The mountis powered but parked while it sits, it is NOT connected to The Sky orACP.  After a period of say several weeks, in which the scope is NOT movedby hand, will reconnect The Sky, activating the ASCOM driver so I can move thescope to clear roof, will then note where the system is pointing after usingthe driver to move the scope back pointed say somewhere in the east…TheSky will show the scope is pointed waaaaaaay off and the RA/Dec display in thedriver will match what The Sky says, but not where the telescope ispointed.  Tonight after startup, after sitting about 4 weeks it told me Iwas pointed about the position of M31…problem is that the system waspointed in Leo, on the other side of the sky.  Had to center on a star byhand (great fun with the CCD camera on the scope) and use The Sky to sync onit, then it knew where it was.  This does not seem to be a problem whenthe scope sits over night.  I do have the computer running a time programthat uses the USNO clock to update the computer time every five minutes.  Any idea here, it is a bit frustrating.  Mike J.

Oh, so to be clear.if there is a delay of a day or two between uses (I

generally run every clear night but we have had horrific for us weather here

in SE AZ), it is OK to leave the mount powered/parked.but if it may be

several weeks between uses, park the mount then power it off.do I have this

right? Of course when monsoon arrives I unplug and disconnect everything.







Another question.I exclusively (well, 99% of the time) DO NOT use the keypad

but the external computer as I am running an automated imaging system. I do

not leave the keypad plugged in but may, on a very very very rare instance

need to plug it in to use the positional control on the handpad when say

checking collimation on the OTA (it is easier to center a star with the

handpad than using the computer). What would be the appropriate AUTOCONNECT

setting in the keypad.yes, EXT, or no?







As I have a GTOCP3 system with Q firmware, is the V1 upgrade available for

my mount?







Thanks for the reply, it was quite frustrating to go out and have the system

be pointing, or say it is pointing way off.

Hi Mike,







The issue arises because the mount is left powered on all that time without

inputs from any source. We generally do not advise leaving a mount powered

up indefinitely unless there is a compelling reason to do so. This puts

the mount at far greater risk of damage from electrostatic discharge.







That being said, the older servo firmware was not written to have the

calendar roll over indefinitely. By leaving the mount powered for several

weeks and then connecting with software, you are effectively allowing the

relationship between the mount's gear angles, the mount's RA and the

time/date to get off. I believe that we have fixed this issue in the most

recent version of the firmware (the V1 chip), but the best bet is still to

power the system off if it will not be used for a long period of time.

Sky, activating the ASCOM driver so I can move the scope to clear roof, will

then note where the system is pointing after using the driver to move the

scope back pointed say somewhere in the east.The Sky will show the scope is

pointed waaaaaaay off and the RA/Dec display in the driver will match what

The Sky says, but not where the telescope is pointed. Tonight after

startup, after sitting about 4 weeks it told me I was pointed about the

position of M31.problem is that the system was pointed in Leo, on the other

side of the sky. Had to center on a star by hand (great fun with the CCD

In your case, just set the keypad to EXT mode. The latest chip we have will keep track of time/date over any amount of time, just the older ones that were shipped originally in the 1200 mount way back will not. You can change the chip in the CP3 any time for more advanced capabilities (such as APCC, etc). Rolando  -----Original Message-----

hi howard -- is the V1 chip different than the V chip?  if so, can you explain the changes?

thanks
