Inspecting the Optics
A Note About the “Flashlight Test: If a flashlight or other high-intensity light source
is pointed down the main telescope tube, the view (depending upon the observer’s
line of sight and the angle of the light) may reveal what appears to be scratches, dark
or bright spots, or just generally uneven coatings, giving the appearance of poor qual-
ity optics. These items are only seen when a high intensity light is transmitted through
lenses or reflected off the mirrors, and can be seen on any high quality optical sys-
tem, including giant research telescopes.
The optical quality of a telescope cannot be judged by the “flashlight test;" the true
test of optical quality can only be conducted through careful star testing.
