Last night I setup my Nexstar + C5 in the old location where I observe indoor, and it's workable. So, I should begin the migration, i.e. to move all my gears there. I shall move one of the plants to my office, and then the rest of the plants will be placed on top of the dry box.
Another project is the motorize the focuser of my C5. Previously I was thinking to sell it, and replaced it with my modified FD 300mm 2.8, but then it's no good at high magnification and so I will keep my C5 and further enhance it.
Tentatively, I will use one of those small motors, add brass gear on the focuser, and then drive it like the Sky Adventurer. Let's see.
