If your main interest is lunar, planetary, double star and cluster observing, I recommend selling both of your scopes right here on AM. Then buy a good used 5"F/8 refractor right here on AM.

Multiple telescope roll off question

Posted By David Goldman

My idea of an observatory is like this:

Roll off roof, either as one roof or split in two. This way you can keep either side open and the other side closed if desired.

Observatory floor built about 2-3 feet above the ground, elevated with wooden stilts. This allows venting, quick cooling, better seeing etc.
This also eliminates a floor slab that can radiate heat thru out the night destroying seeing. It's cheaper too.
Ones the piers are poured, build the observatory all around the piers.

Finally, make the observatory as big as possible...

Good luck.
