Product description

The very compact ZWO Helical Focuser allows for precise focusing of eyepices or cameras. It is ideal in conection with an off-axis-guider and a guide-camera.

The focuser features a female T2-thread on the telescope side, while allowing the attachement of 1.25" equipment on the eyepice/camera side. In addition, there is a male T2 thread on the camera side.

During focusing, the attached accessories keep their orientation and don't rotate. The exact focus position can be fixed with a clamp screw.

Off axis necessity

Review by E. S. on 03.02.2023 09:49:10

( 5 / 5 )

I was delaying the purchase of this item, thinking i do not need it since of axis guider is not a necessity. But i was so wrong. Before getting the focuser I was never able to perfectly focus my off axis camera.

Now the product itself is well, made and feels sturdy, the focusing motion has a good amount of resistance and feels pleasant while allowing fine adjustments. It also has a locking screw to lock the focus position in place. I also liked that it has a ruler indicating the exact focuser position.
