Hi Dan
Checked again with your photo,the current"RA Dec"was not correct when problem occured,please check on your
hand_controller whether you can get the correct current RA DEC when you cant get on Air.
I have tested the following mounts including AZ_GTI,HEQ5_Pro,CEM40,CEM25P,ZEQ25,and no problem found(no iEQ45 on hand)
