Bahtinov focus mask for Sky-Watcher 130PDS

Astroprints Bahtinov Mask for Sky-Watcher 130PDS: focusing without guesswork

With this Astroprints Bahtinov mask, you can focus the Sky-Watcher 130PDS precisely. You place the mask in front of the telescope opening; then point it at a bright star, and you will see a characteristic pattern of three light rays.

If the middle beam is exactly between the two diagonal beams, the focus is perfect. No more guesswork on the screen: the pattern objectively shows when you are in focus, even with fainter stars thanks to the fine slits.

Features

• Objective focusing control via the Bahtinov diffraction pattern
• Fine slits: also usable on less bright stars
• 3D-printed custom fit for the tube opening of the 130PDS
• Placed and removed in seconds

Compatibility

Custom-made for the Sky-Watcher 130PDS. Separate masks exist for other tube diameters; a well-fitting mask does not fall into the tube and is not jammed.
