I'm trying to connect a Mallincam DS2.3+ to a Hyperion Mark III Zoom 8-24mm. The DS2.3+ has what seems like a M25f thread. What adapter rings are required?
Question by: Norman McCall on Dec 19, 2017 5:04:00 AM | 1 Answer(s)
I have recently bought this product to help me get a very short connection for my T2 Zeiss prism to my C9.25 SCT rear port. I find that the two "rings" rotate freely with each other - is it normal? Or is this adapter supposed to be a fixed single piece with no rotating components? I am trying to figure out the best way to tighten this to the rest of my system, so that heavy accessories espcially like binoviewers won't rotate freely by accident!

Well made. What is not clear is that it is made of 3 components - look very closely at the image. This allows you to attach it to the SCT telescope then rotate your rig to suit your needs. A great product although could be less expensive.
