Kendrick Kwik-Fokus Hartmann Mask - for precise focusing and for "off-axis observation"
A multifunctional accessory for photography and observation - clip-on diameter for tubes from 262mm to 272mm.

The Kwik Fokus Hartmann mask is a versatile accessory for your telescope - it allows you to set the best possible focus for observation and photography, as well as off-axis observation of the sun with a suitable solar filter. The mounting is very simple - you put the mask over the optics like a dust cap. Three plastic screws fix the mask to your telescope. You can use the Kwick Focus for all telescope types.

Sharpening with the Kwik Focus
Put the Kwik Focus on your telescope and look through the camera viewfinder or eyepiece after centering a medium bright star. If you are working with an astro camera, substitute short test exposures for looking through the camera viewfinder.
If the optics are not focused accurately, all stars will appear as three points each. As you get closer to focus, these three points move closer together. Just before or after focus, the stars appear triangular. Without Kwik Focus, you would already recognize this area as sufficient sharpness.
Only when the stars are clearly round, as in the center of the image above, you have reached the focus point. You can now remove the mask and start the exposure.

Off-Axis Solar Observation
Close two of the openings with the caps provided and attach a solar filter in front of the third opening. This way the Kwik Focus becomes a good holder for solar filters and thus a base for observing the sun. We recommend the Baader solar filter foil, which we offer for visual and photographic use.
Tube diameter adjustment range:262-272mm
Focusing aid
