Wega Tri Bahtinov Mask for Celestron SC8, EdgeHd 800

The Bahtinov Mask is named after its inventor Pavel Bahtinov. This focusing tool allows precise adjustment of your astro pictures to the focus plane of your telescope or camera lens.

This is how focusing of your camera on your telescope or lens works:

Attach the mask to your telescope and slew the telescope to a bright star.

Turn on your camera and watch your selected star on the live view screen.

If the image isn´t yet in focus, the central line of the Bahtinov pattern is shifted. Adjust your focuser until this very line sits exactly inbetween the other two lines.

Now you have achieved optimal focus. Remove the mask from your optics and you can start the exposure of your object.

Practical advice from Teleskop-Service:

Using a Bahtinov Mask for focusing works especially well for deep sky photography. Correctors and Barlow lenses are not a problem.

Ideally you want to use a star with medium brightness for focusing. It should neither be too dark nor too bright. The lines of the Bahtinov diffraction pattern have to be clearly visible.

The chosen star shouldn´t be positioned in the center of your live view, because most telescopes or lenses, although corrected, do not produce a plane field of view. We recommend to position the star in the outer third of your image. That way, you will achieve a better overall sharpness across your field of view.

The Tri-Bahtinov mask as an adjustment aid:
If you follow the position of the adjustment screws when putting on the mask, you can easily identify the screw to be turned and quickly adjust your telescope perfectly.
