LCROSS Impact - Can I see it?
I have a 4" reflector telescope. Could I see the plume from the impact from my backyard in San Jose, CA?

No, it seems that a 4" won't allow you to see it.
"First, you're going to need a moderately large telescope, somewhere on the order of at least 10 to 12 inches of aperture. Smaller telescopes will probably not be able to do the job and you will definitely not see anything using binoculars. You'll likely need to use magnifications in the 250 to 500-power range to have a legitimate chance of getting a glimpse of the dim impact plume."

Probably not with a 4" but try it anyway at 150-200X. If you have a clock-(or computer-)driven scope and a Meade electronic eyepiece, try it for sure.
Run the feed to a VCR or video camera, watch it on TV, and record it. You could then process the recording on your computer.
Good luck!

However, you can watch it live on NASA TV on the internet.
