  • Q: How can I correct the orientation of the polar scope  on the AZEQ6 ?  I am not talking about calibrating it to the RA axis.  Basically in the standard park position, all the writing on the recticle is upside down.  Note, also that the recticle matches the description of the one in the AZEQ5 manual and not the AZEQ6 manual.
  • Q: I was trying to do polar alignment last night and noticed that the imprint in the FOV is upside down. I cannot rotate the RA axis the full 360 degrees to make the 0 hour at the top of the FOV because the telescope itself gets in the way. I am guessing I need to turn the top of the mount around by unscrewing the assembly on the head and rotating it 180 degrees? i.e. so the counterweight and scope positions are reversed. Is this the case or do I somehow have to reverse the polar scope?

 


The "0" doesn't have to be at the top, as long as the centre of the reticle in the field of view of the polar scope aligns with the RA axis of the mount.

A: It does not need to correct the orientation of the polar scope on the AZ-EQ6 (or any of our EQ mounts with polar scopes). When doing a polar alignment, you always rotate the RA axis to match the orientation of Polaris Position, but it is not necessary to correct the orientation of the polar scope. All the mounts have been pre-aligned in the factory but will still have very tiny mis-alignment due to mechinical or human nature, this does not effect the usage of the mount as long as the object is still in the center of crosshair.The most important thing is the centre of the reticle in the field of view of the polar scope should be aligned with the RA axis of the mount.
