Kendrick Kwik Focuser Masks for Telescopes

Kendrick 14-Inch Kwik Focus - Focusing MaskKENDRICK KWIK FOCUSThe Kendrick Kwik Focus is a multi-purpose tool that is indespensible for anyone wanting to get optimum performace from their telescope and the best possible focus they can achieve.The Kwik Focus can also be used to determine if your telescope's optics are properly aligned and collimated. By observing the out-of-focus star images through the Kwik Focus you can bring your telescope's optics into accurate alignment.It can be used to easily and quicky acheive critical focus for astrophotographers CCD imagers and observers. We believe it is the easiest product to use on the market to achieve accurate focus.By purchasing solar filter inserts the Kwik Focus can also be used as an off-axis solar filter. Full-aperture solar filters will often give a poorer image than a smaller filter because of 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.Constructed of aluminum and powder-coated black Kwik Focus is elegant in both concept and design. It can also be used as a lens cap when your telescope is not in use. When you're using it as a lens cap just place the three plastic plugs that come with the Kwik Focus in the holes on the front of the device.The Kwik Focus works by projecting three images onto the focusing screen of your camera imaging chip of your CCD camera or your eyepiece. As you come closer into focus the three images tighten up and eventually merge. When the images have merged you are at the best focus your system can accomplish. As this is a mechanical focus your eye will no longer compensate for slightly out-of-focus images. Remove the Kwik Focus and shoot image or observe. It is that easy.Unlike other focusing systems on the market Kwik Focus can use the moon planet or any other object that is at least 6th magnitude to focus on. That makes achieving focus much easier!With the Kwik Focus on the end of your telescope all point-source objects will form THREE round images. Turn the focus adjustment in the direction that brings the images closer together. When the images overlap each other and become one you are focused at the best your lens system is capable of. You will find this is easier as power is increased. You can focus right on a planet or the moon and not have to move back and forth between a bright star and the planets. (As other products on the market require). No doubt you have seen articles that recommend under certain conditions stopping down your telescope for better viewing and to help increase contrast and reduce glare. The cap can be left on to do just that when you're viewing a bright object like the Moon. That helps save your dark adaptation and may eliminate the need for a neutral density filter.Other benefits of this device include: Making the splitting of double stars easier. Eliminates difraction from the secondary mirror (in SCT's and Newtonians) Can cancel out most of the problems associated with mirrors that have turned edges or zonal errors. Can be used as an off axis aperture mask to diminish the effects of poor to medium seeing.Kwik Focus may also be used for prime focus on your scope if you want to photograph any nebula. Simply point your camera and scope at the closest sixth magnitude star or brighter near the object of your choice and adjust your focus so all double image star points become single points of light. Take a little extra time here because your star images are very small compared to planet images. When you have finished focusing do not forget to remove the Kwik Focus Cap for maximum light for the camera.Double star watchers will find Kwik Focus helpful in that you will get better resolution of close stars and better colors. The Kwik Focus can also be used as a step down mask to cut down glare when observing the moon. It also acts as an off-axis aperture mask. As an aperutre mask the cap can be rotated until the best surfaces of the mirror are beneath the holes in the Kwik Focus cap. Planetary observation is enhanced by the reduction of the effects of nominal seeing lengthening the focal ratio of your telescope and eliminating the light-scattering effect of the secondary mirror.The Kwik Focus is presently only available for the Meade ETX Celestron C5 Astro Physics Traveler 130mm and 155mm refractors Televue 101 the Meade 7 Maksutov-Cassegrain and 8 9.25 10 11 12 14 and 16 Schmidt Cassegrain Telescopes.
