The Kendrick Kwik Focus is a multi-purpose tool that helps get the best possible focus of a telescope for visual and astrophotograpic use. It can also be used to determine if the telescope's optics are properly aligned and collimated. By observing an out of focus star image through the Kwik Focus, you can bring the telescope optics into accurate alignment. It can also be used as a lens cap.
With optional solar filter inserts (available from Kendrick) the Kwik Focus can be used as an off-axis solar filter. Full aperture solar filters often give a poorer image than a smaller filter because of the secondary obstruction and poor seeing conditions caused by the sun's heating of the atmosphere. An off-axis filter removes the image degrading influence of the secondary and minimzes the effects of atmospheric turbulence to give a better solar image.
