Thank you all for your kind welcome (and info)
Firstly, as a beginner I have found the whole business of buying a telescope and mount rather shabby! Maybe it was just me, but talk about amateur! If I treated my customers the way I have been treated I would be out of business... I guess you can get away with that level of service in a niche area.
If anyone is interested I can open another thread detailing my experience as a complete beginner in buying a telescope, let me know.
Now, onto better topics; you guys have been great, a fantastic source of info!
Onto specifics; I have decided not to buy the 15 mm eyepiece, maybe it was the capital letters, maybe it was just the 'DON"T BUY ONE' message, but I got the feeling I should look into the topic of eyepieces a bit more before I buy another one! Thanks.
Tassie, thanks for the kind invites, I am going overnight on the Spirit of Tasmania on 28 May, I have a couple of nights booked at Low Head, and a couple near Bicheno, then I'm off back to Sydney, so I have no real time to catch up with anyone. I was planning on dragging my new toy along with me, mostly in the hope that I can play at least once in a dark sky situation.
Now, for the lurkers/bods who come along in the months to come and do a search looking for the exact same info that I was;
The Megrez II 80 FD APO requires an extension tube of about 2" (or 50-55mm)... which seems a bit dumb to me; why didn't they make the tube 2" longer!
