Hi Rob

Just curious as to where you purchased the watch, the brand and cost.  Sounds like it could come in handy.

The other question is about the Canon T70s camera body.  You said it can be programmed for multiple time
exposures.  You would be able to for instance program it to take a sequence of 10 or 20, five minute
exposures.  I have thought in the past this would be a great idea but had no idea they even existed, esp with
the fact they don't drain on the battery power.  What would be the availability of one of these ?

Thanks in advance, Adam Marsh, ASV Meteor Section.
