I would love to do some collimation with the camera on the scope, but with a portable setup I would rather be imaging with that time.

I'm using Catseye too, have since nailed collimation but still no joy, have also washed both mirrors, they came out almost looking new, but still no joy. My stars are still bloated and just can't get detail in nebula.
Cleaned mirrors, nicely collimated and good focus pretty much just leaves a poor figure in the primary as the prime suspect
