20 mw might barely make it, but I think it might. mine is around 40-50 and it lights up clouds when they are low.
I think you'll definitely see the beam although it might be a bit dim all the way up into the sky, but light pollution affects it's visiblity greatly.

Thanks. It's not bad for a second try. I might set it up again and try to light up the "ground" a little more so they don't look like they're just floating there. It's actually an old computer case with a black sweatshirt draped over it.
I have a Nexstar 8 GPS (8" aperture Schmidt Cassegrain) Meade makes some great scopes too.
Try and get the largest aperture you can afford but don't forget that a proper mount is important for astrophotography too.
A lot of large aperture refractor scopes do well in astrophotography too but they are expensive.
http://www.astromart.com/ is a good place to learn some more before buying a scope.

Neat. As long as it's kind of visible if you keep doing it it'll show up in a long enough exposure. I've done some crazy stuff for the sake of photography. It usually involves laying in ditches, or playing with bugs, but if it would be cool enough I'd consider ponying up for a laser.

Hmmm..... that.
weather balloon
and a few other toys, controller, speaker with some spooky sounds.. etc.
And you're all set for you very own UFO hoax
Scare the bejesus out of your neighbors...
Just make sure the people you pull the hoax on are like the typical people who spot UFO's:
"uh yuh, it sure was bright. Them thar aliens shot up ol' Fido's dog house with one of them thar tractor beams. I'm thinkin they means to give Fido an anal probin' or sumtin."
sort of. It's not really economical, though, since the stuff you have to buy pre-assembled is 90% of the cost anyway.
You're better off building a CO2 laser if you want powerful homebuilt...it's even invisible, and can burn through stuff

Yeah you can get a 5mw one for like $79 here in the states, then do the pot mod and have a 20-30mw laser for cheap.
Sorry about your pet bird Goosemaster. I lost my little buddy to old age and poor health recently too so i know your pain. He was my best little buddy. goofus
