I use the GM-8 mostly for solar imaging and visual with a tandem bar set-up (Cak70 and TV76 w/SF70 h-alpha filters). I've not used it for dark sky imaging but I do use it for visual at night with a 105.
I hate having equipment lying around unused and I figure with the Mach 1 in house, the GM8 will be staying indoors a lot. She sure is pretty though and kind of like a "not so old" friend. Maybe I should just think of the GM8 as my solar mount and dedicate it to that (wouldn't want the anodizing to bleach on that Mach 1 ).
I'm torn though - what would you folks do? I know from seeing photos of some of your living rooms that some of your pads would qualify as scope/mount showrooms, LOL. I'm more in the Spartan camp and my spouse doesn't share the view that my gear is like industrial art.
