Don’t quite understand the last question, you need 2 cameras , an imaging camera in the scopes focuser and a guide camera riding piggy back on your scope.
The imaging cameras long exposures has nothing to do with the guide cameras 2 or 3 sec short exposures, 2 completely different systems and not connected in any way
The guide camera locks onto a guide star in the same field as your intended image target and makes micro corrections to the mount to keep the guide star locked on for minimum polar align error
PHD2 is all about locking on to a good unsaturated guide star and then the software does the rest. Obviously seeing conditions , wind , scope flexure and lots of other factors determine how well you guide
This then allows the separate imaging camera to take long exposures day 5 of 10 minutes of the intended target
I just wanted to know if you knew the concept of PHD2 guiding
Cheers
