I like Greg's design the best. I like the idea of a cover to keep the dust out. I just need to adapt it for a 4" scope. I'm thinking about doing this in January. The cold weather has me putting astronomy on hold for a while. Maybe I'll get out toward the end of the month if we get some warmer nights. When it gets up to 60 degrees in the daytime, the nights are more tolerable. Debbie
