Thats not a bad idea with the streetlight! i may try it, and while im at it i think i'll sabotage every halogen security light in my neighborhood too.

What exactly are filters used for? Do they just alter the colour of the images you see? Or is there more to it than that?

There certainly is. I bit the bullet last Wednesday and went ahead and ordered the 130 . 2 days later it arrived! unfortunately though there hasnt been a clear night in bristol since then so havent had a chance to test it out. that didnt stop me setting it up in my living room though, and in terms of build quality/ ease of assembly i cant fault it yet. im also awaiting delivery on a barlow lens and moon filter so hopefully they'l arrive in time with a good clear night and i can finally get out there and enjoy the night sky in a bit more detail.
