I recently started getting in to astronomy, and have been sorta doing astronomy-stuff for the past few weeks. I currently stargaze with binoculars, and i have pretty much seen everything that could be seen with them.
Sorry, I hate to disagree with you, but a lifetime isn't long enough to see everything that can be seen with a good pair of hand-held binoculars.
Just to take one example, have you seen all of the Messier objects? And how many double stars have you split?
I'm looking for something that can be easily carried around on a bike / in a backpack, so something like a travel scope. My budget is around 160-180 euro's, max 200-210. i don't really want anything less than 80mm in refractors and 130mm in Newtonian styled scopes. I would prefer a 90mm refractor but those are a bit pricey. i don't know if i should use an Equatorial mount or something simple like an alt/az. I am currently only looking at refractors, because of the compactness of them, but other telescopes like newtonians and maks are welcome.
I do carry telescopes on my bicycle fairly often, so I can answer this with some authority!
In general, you will probably want to strap the tripod to the bicycle. It is possible to carry a tripod in a backpack, but since it's most of the weight, it's more comfortable not to have all that weight on your back. The telescope, however, should go into the backpack to protect it from jolts and vibration.
An alternative would be to take a very small Dob like the Heritage 130P, put it on the ground, and sit next to it on the ground. When I did this I found that I wanted a cushion about 5-10 mm thick to get me up to the correct height, but that's easily arranged. I am comfortable sitting for long periods cross-legged on the ground, but many people aren't.
Assuming that you want to use a tripod, a refractor is probably your best choice. Maks offer similar portability per unit of performance, but have very narrow fields of view, which makes it much harder to locate objects. And robs you of the glorious wide-field views that a small, fast refractor can provide.
The tripod itself should be a good, sturdy photo tripod -- expensive but highly portable. You can often find good ones for cheap on the used market. If you care about portability, don't even think about equatorial mounts!
I have carried refractors as big as a 100-mm f/6 achromat in my backpack, but that might stretch both your budget and your portability limits. See this thread for a description of the 80-mm GoScope that I will be bringing to South America in a few days. I chose that scope because it works particularly well with a ballhead mounted "side-saddle." From an optical standpoint, one of the lightweight 80-mm f/5 refractors would be slightly better, and perhaps easier to find in Europe.
