Yehhh allllright then. I'll bring it along.
It turns out that AOE didn't have a 90mm short tube in stock, so I changed the order to the 80mm long tube, which is the scope that I wanted in the first place anyway. It will be good to compare the CA of the AOE80L to the ED80. The 80L has an F ratio that is almost 4 times the aperture in inches so it just about meets that "special" achromat formula rule thingy...
