If your Esprit has a heavy camera with a filter wheel and a flattener, you want the focus ring to keep everything in place and focus precisely. With these adapters, you can mount the Feather Touch FTF3035B-A on a Sky-Watcher Esprit 120 or Esprit 150.
The FTF3035B-A is a 3 inch focuser from Starlight Instruments. The adapters replace the original focuser and connect the tube to the Feather Touch. The Esprit refractors are widely used for astrophotography, for example with the 0.77x reducer-flattener for the Esprit 120.
After the conversion, check the distance between the flattener and the sensor; a different focus lens can move the focus point. Keep the lens covered while changing the focus lens. To learn how to set up a photography setup, read our astrophotography course.
If you want to focus with a motor later, then look at the Wireless MicroTouch for 3 inch.
