Hi Chris,
We had a look at Iota Cancri at Deep Sky Camp, February 2005, I have put the obs list on a spreadsheet at last, so could look it up!
It's a nice wide double at X53 in the Zeiss, the primary is a Barium Star.
Hope to see you tonight, Jeff

Hi Jeff, or should I call you Miriam at night?

Anyways, do we have a list of colourful doubles I can bog at, if by any chance the skies are clear this weekend.  I'm not holding out for luck because I have got very wet a couple of times recently.

Also are there any quick moving Binaries us imagers can have a bash at over the weekend, I was thinking of one near cassiopia if you can find one?  I can take 30 minutes of images on it every few hours and then provide a variable magnitude chart.  I'm liooking for something with a 3-6 day cycle?
