In my experience, it didn't do much to make it look like a longer exposure. That may be because of the light pollution where I was, or the relatively small number of exposures I was toying with. It does, however, clean up some of the noise in the pictures. Not really an issue when you're only using ~20 second exposures, especially if you use a dark frame and a bias frame. For longer exposures, though, the noise starts adding up, and multiple exposures are a must.
I'm still saving up for a nice telescope and mount, so I don't have much experience with high end stuff - mainly just pointing my camera at the sky and shooting right now - so take all of that with a grain of salt. Give me a year to save up the money I need for a nice 8-12" SCT, a guidescope, and a few other things and hopefully I'll know more.
