Thanks Graeme

I really appreciate your input and you also make a good point. But please correct me if I'm wrong, with a larger apeture and longer focal length I can take close up images of smaller DSOs, for example many Planetary Nebulas and distant Galaxy Clusters? This is something I'm looking at achieving, that said I also love the widefield images of an ED80 or of a slightly larger apeture

essentailly I'd like the best of both worlds
And many thanks for your kind glowing words about my image gallery, you are the first one here to mention it and its nice receive such compliments. Yep the Pyramids was definately a surprise and I was fortunate enough to have a good camera and lens handy to record that moment
Cheers!
