Actually with the Nexus it can make a difference. This may not be the problem but it can make a difference.

Generally with that much difference I'd suggest you are seeing slippage in one of the encoders. Generally the ALT is the culprit. Make sure the ALT encoder arm is not pushing up or down on the encoder shaft or twisting it.?

Re: Nexus DSC - object selection
Hello Steve,
The filter will be reset upon a power cycle of Nexus DSC Pro. It is implemented this way to avoid the situations you have described - in case the filter is enabled and by the next time you observe you may not remember having the filter enabled.
I suspect the filter was accidentally enabled which resulted in the behaviour you described.
Best Regards,

The Nexus is on Amelia's 15" Obsession.?
However the Nexus worked perfectly last night. Since we are just starting out, she would select an object and use push-to to move the scope. The Nexus would get her very close to the object.??

Something similar with the NGC catalog. Request one specific object and a different NGC object is displayed.

The first couple of objects we selected during the night were fine, no issue. But after some use, the above issue started happening.

no need to check the front if you know you have a Gen2 handpad. The Gen2 is not compatible with a Gen3 and vice versa.

Re: servocat and nexus dsc pro
You need to open ServoCAT and change three jumpers to configure it the same way as for Argo Navis - please see the attached photo. You do not need a new cable to connect the serial port on Nexus DSC Pro to the DSC port on ServoCAT.
