Glad that you like it Dave
How would you compare value for money to the 120mm achromat you recently bought? ( I think I know the answer
) .
Any balance issues with the 31nag ?
One thing we could try next time we meet is comparing the 27mm panoptic to the 30mm SV.
(OT: that quasar sure sounds like a fascinating object, just had a read about it here
