adjust pointing model offset

[whwiii]

apologies if this is a FAQ

 

i have pointing model which works reasonably well, but somehow got off by a bit.  every night i power the DDM60 up, do a home find and slew to a star, the mount is off by several degrees.  i point to the correct location, sync and it works fine for the rest of the evening.  next night i start up and the mount is off by 2 degrees in the exact same direction.  have tried saving the settings after sync to no avail. 

can someone tell me the exact steps necessary to correct the offset?

 

thanks

Hi Bill

 

Have you tried to set the new home position after a successful sync with your pointing model? Then don't forget to save all settings before quit! Whenever I have such a problem this is the reason for the offset during startup.  If it does not work try this:

 

1. Create new pointing model

2. Save and use on next start

3. Set new home position

4. Save all settings

5. Try to restart Autoslew, do a home find and now you should have your target centered again.

 

Good luck!

It is also a good idea to check the clock in the PC. Is the offset in RA only or RA and DEC?
