Both the body of the VarioFinder and the included prism both do have male T-threads, so you can simply remove the existing eyepiece clamp or the Polaris eyepiece, which is attached to the prism via the T-thread, and replace them with any of our T-2-focusers like the Baader Focusing Eyepiece Holder 1¼" / T-2 # 2458125.
These focusers also fit onto all our T-2-prisms and mirrors, including the one supplied with the VarioFinder.
So, you can easily replace e.g. the Polaris Crosshair-eyepiece with the Baader Focusing Eyepiece Holder 1¼" / T-2 # 2458125 and use your existing 1¼" eyepieces.
You can also combine the Polaris with Baader Nose piece 1¼" / T-2 # 2458105 and use it with every other telescope.
