This video explains how backfocus is set on the william optics zenithstar Z61 and zenithstar Z73. I also go over basic set ups with a dedicated astrocam DSLR and Mirrorless camera. I share how to read the diagram william optics sends with scopes about backfocus and how it is adjusted and what spacing to use on each refractor. If you missed my comparison video on the William Optics Zenthstar Z61 and Z73 check it out here! https://youtu.be/3YqTjTkYAos Thanks to my subscribers!
