Well, I took the plunge and picked up the 13mm T6 Nagler. Just have to wait for a clear night now to give it a go! Thanks again for all the feedback.
I'm sure I'll want a smaller focal length eyepiece later on, for nice planetary views without needing to barlow (maybe the 8.5mm XF, or a Radian perhaps?), but I'm sure I'll be very happy with the Nagler, and I'm also sure we could all name just one more thing we need
