Thanks astro, that's just the kind of info I'm after....
Regarding your suggestions for eyepieces and barlows, that sounds like a very good combination, but I'm not ready to make that kind of investment yet....down the track I might end up with such a collection, but at the moment that's just not realistic for my budget and experience....but, it's food for thought and maybe I should have some sort of long-term plan here...
