I want to share some of my observing procedures involved with my 18" NMT dob. At my old place in the city, I had to keep my original 18" in those and roll it out with ramps. Later I stored it in a trailer with ramp doors. The worked in the city as the heat island kept condensation from forming inside the trailer. I moved to the far suburbs where the humidity is much worse. Now the scope stays in the garage fully assembled.
For star party use the scope is easy to take apart and transport. The second pic is the 18 with its little brother 10"
