Thanks for that tip on the Delos Groboz, I would not have thought about the refocusing problem. Will have a look at those Delos later in the year.
It sounds like that Pan24 and the Nagler13 is a winning combo. Then I think I can't go wrong either with the Pan24/Denk14 combo either. I have just got my costs in and either way its looking to be around $900NZD for the two eyepieces landed and duty paid for in NZ. So am off to the bank today to top up the credit card so I can do the order.
Again, a massive thanks to you all for all your input and advice.
I will be sure to get the wife to place some comments and her thoughts on the eyepieces once she gets them to help other people who may be in the same boat.
