I have an ED80 and until the burgulars took off with my 2x teleconverter, I used it very successfully with the ED80.
However I probably should have bought the ED100 or similar instead to give me a longer focal length. Unfortunately when I got the ED80, there were no ED100's available and being the impatient type....
Really the ED80 is a great little 'scope - light, portable and fits in a suitcase no problems. The ED100 is really too long to take on many holidaze. Having said that, I would still like a long focal length scope. When I was at uni, there was a 6" f15, making the whole thing about 2.5 m long. It needed two people to handle it and any breeze would sent it a'wobbling, but the views of the planets was amazing.
