What is the purpose of the Black color bushing long for SESTO SENSO 2?
This bushing makes first-generation SESTO SENSO adapters compatible with the newer SESTO SENSO 2 motor. It is a necessary component if you are upgrading your motor but want to continue using an existing adapter designed for a focuser with a large-diameter shaft.
I'm upgrading from the original SESTO SENSO to the SESTO SENSO 2. Can I reuse my old focuser adapter?
Yes, provided you have this long black bushing. Your original adapter for a larger focuser (like those for FeatherTouch models) can be used with the SESTO SENSO 2 by simply installing this component, saving you the expense of a new adapter.
Will this bushing work with the first-generation SESTO SENSO motor?
No. This bushing is designed exclusively for the SESTO SENSO 2. It will not fit or function with the original SESTO SENSO motor.
My telescope has a large focuser, like a FeatherTouch. Is this bushing what I need for my SESTO SENSO 2?
If you already own an adapter for that focuser from a first-generation SESTO SENSO, then yes, this bushing is the only additional part you need to make it work with your new SESTO SENSO 2. If you are buying a new adapter, this bushing is typically included.
Why is a special bushing needed to use older adapters with the SESTO SENSO 2?
The design of the SESTO SENSO 2 motor coupling is different from the first generation. This bushing adapts the mechanical interface of the older, larger adapters to securely fit the new motor, ensuring precise and slip-free operation.
Is this bushing included when I buy a new SESTO SENSO 2?
No, the bushing is not included with the SESTO SENSO 2 motor itself. It is included with specific new adapters for larger focusers or sold separately here for users upgrading from the previous generation.
