Hi duncan
Perhaps the visit to FNQ will have to wait. Aren't you guys under a few feet or water - or is that just Townsville. Not sure I'd want my mirror sinking under floodwaters as I swung the scope to the zenith
Anyway, on topic, I did try putting my "somewhat better than el-cheapo" 30mm eyepiece into a paracorr in my f6 and - nope, no better. Maybe because it was an f6, but probably there is a limit to what you can do with cheaper eyepieces. Invest in better glass and see how that goes before you think of a paracorr. I reckon you'd be happier with a $400 eyepiece than investing that sum in a paracorr. Keep inviting and I'm sure someone will come and visit you with a case full of lovely eyepieces for you to try.
