We think the Orion 15170 case is the closest replacement for this case. However you need to add 10 inches of padding to make it work. That allows you to place your hand controller and other accessories in the foam.
Constructed of rugged, Cordura nylon, the bag includes a strong, broad strap to make carrying easy and comfortable. Each case accepts the optical tube assembly and fork mount of the telescope and is designed to use the molded foam-rubber insert in which the telescope was originally shipped. It's for secure storage and especially field transport of your telescope.
