The new 28" is under construction . . . So the time has come to pass this excellent scope on to a new owner.
The 20" has been my deep sky workhorse for the last 5 years. I've observed 93 Hickson Galaxy Clusters, 9 Andromeda Globulars, a dozen Palomar Globulars, many Abell Galaxy Groups, and on and on with this scope. It has been wonderful.
This is a very solid and stable telescope. It has nice positive, smooth motions. It is not too tall. Just a little two step ladder is all that is needed.
The scope comes apart into only 2 pieces. The rocker/mirror box assembly, and the truss/upper cage assembly. This makes it a snap to assemble and collimate, but it is not a small compact package. I kept it in a 5x8 haulmark trailer and just hitched it up and took off for the mountains.
I'd like to sell it to someone within driving distance of Washington DC if possible. This would be difficult to ship.
