Re: Tracking Accuracy

Howard Dutton

I don't know what's going on there but it's not isolated to just the RA axis and "tracking."

Unguided imaging is unforgiving.  Even if the mount is perfect there can still be no bending or wobble or other movement of the OTA/optics/focuser/camera.  These things need to be stable in a "beyond human perception" kind of way.  No walking around the scope tripod.  How much of a breeze is ok?  Cables from camera shift.  Etc. Etc. Etc.
