This is a replacement set of rings for Explore Scientific's 152mm Doublet Achromatic Refractor. It is perfectly sized for the DAR 152, and can be adapted to similar size telescopes as well with minimal effort. It exactly matches the standard rings included with the DAR 152, and acts as a perfect replacement if your rings are damaged or lost.
These rings use a hinge system to make it easy to separate and re-connect smoothly. The rings have a carry handle on top that can be slotted in and out for transportation purposes, and when the handle is removed the slot can be used to attach anything that connects with 1/4-20 standard bolts.
