Hi guys ,I’ve got a Skywatcher 150mm Maksutov Cassegrain, Black Diamond series ,Looking for an adapter to suit a dual speed focuser for a 8” SCT Meade , (I have a William Optics micro focuser to suit a SCT) the sizes are different at the back of these scopes, are there adapters available ?? or can I get an adapter made The thread at the back of the Mak has an approximate size of 66.5mm outside diameter, and the thread inside the sct focuser is approx 50mm, so I will need an adapter that steps down from this to suit this focuser. Any Ideas ???? your help with this will be much appreciated. Thanks regards John
