You might find the Nagler is suddenly transformed with a paracorr in that fast scope.

Yes, astigmatism is considerable, and no more or less than the Nagler. Shame I couldn't compare both at the same time, I'm really relying on my memory for the comparison, but I remember being really disappointed with the Nagler, and surprised with the Andrews.
The problem with adding a paracorr is the increase in weight at the top of the dob. It starts to get too top heavy. The Panoptic range of EPs is brilliant too, well corrected and 68*FOV. But we are again talking BIG bucks. Then when you add the cost of a paracorr, mate, when does it stop?
If your pockets do have a limited depth, there are still ok choices. That's the mission I've set myself on,
