The ol' hand grenades (Naglers, if you get either a 32 or 40mm EP, you'll see what I mean
) are excellent EP's. However I here that the Ethos EP's are even better. Really though, it's a pick of two excellent EP's. You can't go wrong with either of them.
Ick!!!!...make sure you clean out your scope's tube and the focuser of any grit and dust!!!. That'll ruin your focuser quicker than anything, and it won't do the optics any good either. Be like rubbing them with sandpaper!!!.
Uranus is a blue-green colour. I'd say it was the dust that was making it brown. That and you viewed it low to the horizon...blue light gets scattered the most close to the horizon. That's why sunsets are red....red light, because of its longer wavelength, doesn't scatter as much and you see it more easily.
