David,

I've been using this for a day now, key points I've gained through reading are:

1. Have a shot that includes 30 - 100 stars, do this by maybe taking a 5 - 15 second shot and setting the Sigma parameter to around 70
2. Calculate your imaging scale and set your units accordingly and provide upper and lower bounds; for me that is arcsecperix as unit with a 0.2 - 0.8 range (mine is just under 0.44 arc sec / pixel)
3. I use the parameters other have suggested -H and -L and -r -c 0.02 - seem to work okay
4. I searched originally 180 degrees of sky - will try 30 degree, given my pointing that is still vast versus my current pointing.
5. Try asking on the Cloudy Nights forum for more info; the AT developers seem to hang out a bit there!

Cheers,
