With an OAG, my guide scale is very close to the main imaging scale. I would like to dither by 15-20 main camera pixels to fully eliminate walking noise, but the entry field maxes out at 10.0. Can that be increased?

The 2nd part is an impossible request, I suppose, given how the parts fit together. I recently swapped back and forth from OAG to guide scope and then, last night, back to the OAG for my RC6. I have saved equipment profiles for each configuration. In the last swap back to the OAG I forgot to go into the Guide Options window to reset the dither settings from the 1.5 pixels appropriate for the guide scope to the max setting for the OAG. I ended up with massive walking noise.

Ron,

What is walking noise?

I have an OAG and dither by 2 or 3 pixels randomly using PHD2 and have no issues doing so.

I guide with the default 2pix in Ekos internal guider. Never had a problem with the walking noise (with RC6 and smaller).
No OAG, though.
