OMG ! has it *really* been that long a time???
I witnessed the early impacts with friends ( G'day Col & Chris if you are reading this) through my C-11 at the time....(still a great scope IMHO) and also grabbing some images (attached) with a...wait for it..... ST4-X CCD
I recall seeing what looked like a "shock wave" extending from the impact site. A fantastic time for sure.
Thanks for jogging fond memories !
