Not when there's a storm blowing like here!

But, seriously, thanks for that - it's kind of what I was trying to do last night, except I was skipping the open clusters, as I've never found them that exciting (though I have spent some time looking at the Pleiedes and Hyades). I shall search them out when the sky is clear and look forward to the next instalment.
I have my copy of Hartungs on order, but it's not turned up yet......
