Ken,
as well as Eric's comments there is a "Meade_DSI" yahoo group. I noticed you joined the Deep-Sky-Imager group. Just wanted to let you know there is another group, and the info on each site is different. I found the meade_dsi group to have the best tips + tricks
Especially on focussing and the use of the histograms..
Just wanted to let you know..
cheers
Mark
