These should work with any focuser that utilizes a ¼ inch D-shaft. I made three sizes - 75mm, 100mm, and 125mm (3, 4, and 5 inches - ish). The 75mm allows my scope to still fit nicely in the factory case. If you don't have a factory hard case, and clearance allows, the larger sizes will allow even finer focus control.
