tube rings
here is a quick sketch of a new design of tube rings l am having a prototype made of at the moment, normal tube rings are rather expensive especially when it comes to the larger sizes because every different size has to be individually cast, with my design the hinge and tensioning bracket are interchangeable between any size ring so you only have to buy the actual split rings whenever you change ring sizes and bolt your existing brackets to them. Because of this, buying a new set of rings becomes significantly reduced, the rings can also be matched to a 60mm wide dovetail which is also being made up therefore giving the rings much more stability, these connectors can also be mounted on top to mount guidescopes or cameras. The larger rings will give much more stability when mounting SCT's on EQ mounts.
