I just purchased my first refractor, a William Optics Zenithstar 73 in red. I love it, the build is amazing and the optics are great. I am going to use it for astrophotography on a Celestron AVX mount. It came with a nice soft case, but would like to store it with the saddle and mount rings extended, so it's faster to pick up and mount on the AVX. The soft case it just too short for that purpose. What are other folks using for a case?
