Hi Tony--thanks for the input! 

I was impressed by Rick Krejci's results (for example:
www.ricksastro.com/Gallery/htm/SXV_M20_e160.htm).
The smaller size and lower mass of the Starlight gear seem about like
hanging a
camera on my scope compared with
with the lunchbox mass of a SBIG camera. That and not needing to even think
about dark frames is pretty interesting.

I'll take this off line rather than risk spinning up the dark side wars
again. 
I'd love to hear more from anybody else who 
has considered alternatives to SBIG equipment.

Steve
