Some good light weight refractor telescopes?

I'm doing a project that I've been working on for about a year which requires my evening time to go and stargaze whenever the sky is clear. Recently, I've been only able to use binoculars, which is not exactly helping my project that much. I'm looking to buy my first telescope soon. But I'm looking for a light weight refractor that can be set up easily and put away easily. I've been looking for sometime, so I'd like to get some opinions and possibly suggestions. Thanks

My stock answer for a first scope is an 8" dob, but since you mention a lightweight refractor, I would consider something like a celestron 80ED (used under $300) and an alt-az mount like the astrotech voyager, or maybe a used vixen polaris to be used in alt-az mode. A very capable rig for casual lunar and planetary views, and fine widefield views, but not great for going deep due to small aperture. Perhaps if you explained the nature of your evening project you would elicit further response.

I like George's suggestion of an 8" Dob for hunting down Messier objects, but if you must have a refractor, I'd consider an Orion (or similar) Short-Tube 120mm f/5 on a simple Alt-Az mount. I like the Unistar mounts, but Orion sells a VersaGo mount that would be easy to use. However, it is not going to go as deep as the 8" Dob; it won't be as good on planets; and it is going to cost about twice as much.

OTOH, you could try doing a binocular Marathon, and upgrade your binoculars to 15x70's on a parallelogram mount. They should be capable of pulling in 50 objects off the M list.
