(meteorobs) Meteor cameras? lower cost, more sensitivity, COLOR & BW

[stange]

I'll take your word for it Chris.

I wondered why there was no detailed S/N specifications or anything else on 
its performance. It does not even have an image of the connector cable and 
no instructions are available on line to detrmine even if it is NTSC 
Composite.
