Yeah thanks for your thoughts mate - its really a matter of thinking; i'm starting an eyepiece collection from scratch, and it doesn't matter how long it takes me to acquire them... so I may as well do it properly
That said, I'm sure i'll be just as happy with the 13mm t6, and in a lot of ways i would probably be better off getting the Nagler + 24mm panoptic for the same price. Decisions, decisions....
