Many Observers Harbor Misgivings About Their Telescope. The Manufacturer May Have Guaranteed Accuracy To Onequarter Wavelength Or As Diffractionlimited But Most Telescope Users Have, At Best, Only A Hazy Idea Of How To Personally Verifying Such Claims. Sure, There Are Ways To Check The Accuracy Of Individual Components But For Many They Are Hard To Understand Or Require Costly Reference Optics And Other Test Equipment. Besides, Telescope Users Are Interested In The Performance Of The Entire Optical Train, Not Just The Main Optical Element. What Is Really Needed Is A Test That Can Be Used At The Observing Site, So That All The Problems That Impact On A Telescope'S Performance Can Be Diagnosed. Isn'T There A Simpler And More Complete Way Than The Complicated Shop Tests? Yes, The Star Test Is Such A Method. It Uses The Entire Working Telescope. It Isnot A Poor Substitute Or A Workaround That Uses Bits And Pieces Of The Optical System. It Is The Oldest And Most Sensitive Of The Optical Tests An Inspection Of The Diffraction Image Itself. Startest Results Apply To The Complete Imaging Performance Of The Telescope. The Star Test Is Lightningfast And Requires Only A Good Highpower Eyepiece. It Tests The Telescope For Precisely What It Was Meant To Do. Bad Or Poorlyaligned Instruments Fail The Star Test Unambiguously. The Star Test Often Allows You To Correct The Optical Difficulty Immediately In The Field, When You Might Be Frantic T
