HyperStar Standard Adapter Top Replacement

The only purpose of this adapter is to replace the top of an already existing HyperStar adapter to change its thread type.  An example of this is if you have a ZWO 294MC pro with M42 threads, and you bought a ZWO 6200 Pro with M54 threads. Each camera has the same backfocus but the threads to attach it are different. This saves you the cost of buying a second adapter when you only need a different thread. All other adapters for the HyperStar can be found here.
