Yes, Greg, I agree with you. It's quite important to keep the TEC140 and TEC180 discussion quite separate. I make no "claim" about the TEC180 as I've never tried my Trius on that scope. It may very well have a different colour correction than the TEC140. In fact, I'm unable to find any colour correction data on the TEC site about the TEC180 at all. Do you happen to have anything?
And again, I stress that the blue issue I see on the TEC140 is perhaps due to the way it is corrected AND exaggerated by the super hi QE of the Trius. At least my own tests seem to indicate this. However, the large star issue is probably something quite different once blue is taken care of. It may be something seen by both scopes and probably has much more to do with the camera and the way it is used rather than either scope.
Your eventual test of the AP130 will be most interesting!
Peter
