Star Testing Astronomical Telescopes (2nd ed.). (Richmond VA: Willmann-Bell, 2008.) The book that popularized the star testing of astronomical optics, Suiter also provides an excellent discussion of aperture and apodizing masks, secondary obstructions, collimation and many other issues that affect a telescope’s optics.
A Cheshire eyepiece or Cheshire collimator is a simple tool that helps aligning the optical axes of the mirrors or lenses of a telescope, a process called collimation.
Star Testing Astronomical Telescopes (Willman-Bell, ISBN 943396-44-1). This is a great book, and every amateur should have a copy, even if it does get areally problematical scopes out little deep in places. But a quick look at the first couple of chapters, a little staring at unfocused stars with your scope, and perhaps a few afternoons playing with Cor Berevoets’ Aberrator, a freeware
A star test also reveals a feature of a telescope’s optics known as spherical aberration. It happens because the outer parts of the mirrors or lenses don’t bring light rays to the same point of focus as those hitting the centre.

The star test is a classic test of optical quality based on examination of the Airy disc and expanded diffraction rings of a point source of light, used mainly for telescope and microscope objectives.
This book has probably everything you may want to know about the theory of star testing. It is a purely theoretical book based on state of the art calculations of the diffraction phenomena in astronomical telescopes peformed and written by a physicist.
The test has been performed in a closed corridor, with an artificial star of 35mm and with a distance from the focal plane of the camera (Point Grey Flea2 FL2-08S2C-C) to the artificial star of 51:08m 5cm.

19/09/2012 · Hi andrew yes i have tested two orion mirrors a 10 inch and a 12 inch. by the only test method availiable to me namely star testing and a star test using a ronchi grating eyepiece , and although the test is a bit subjective they were good mirrors never said they were not They appeared to be as claimed in the test reports ,but they did exibit faults typically found in mass produced commercial
The star test is a classic test of optical quality based on examination of the Airy disc and expanded diffraction rings of a point source of light, used mainly for telescope and microscope objectives.
The diffraction ring on the inside of focus was “textbook” (i.e., Harold Suiter’s book on “Star Testing Astronomical Telescopes”). The image on the outside of focus was not as sharp, but my “floaters” were interfering with making a good assessment. Jupiter was up, but is low in the sky this time of year; nevertheless, the image was excellent. The belts were distinct and showed
Star Testing Your Telescope the magnitude of the defect. Severe errors on any telescope include astigmatism that origi-nates on the glass, bad zones or severe roughness. These warrant returning the telescope. If the errors are minor, weigh the likelihood that you will get better optics at the same price. Also consider what you bought the telescope to do. If yours is a low-cost light bucket, be

The star test is a powerful but inexpensive way of obtaining better resolution and contrast. With this book most observers will find that they don’t need a new telescope because they now can test, diagnose and fix the one they have. Using Star Testing Astronomical Telescopes as a guide, your telescope will perform to the best of it’s abilities and perhaps it will show images better than you

A star test also reveals a feature of a telescope’s optics known as spherical aberration. It happens because the outer parts of the mirrors or lenses don’t bring light rays to the same point of focus as those hitting the centre.
