Aspect of a High pressure Sodium far streetlight
as seen when centered on peeled CD hole (at about 5 cm from eye)
!!!! NEVER USE this for the SUN !!!!
The yellow-red is main Sodium D-line, the turquoise is also a Sodium band, most of the other bands from green to violet arise from contained Mercury.

Spectra software : most interesting !
Testing astronomy filters on a high pressure sodium light
LCD spectrum , also with anaglyphic glasses
click on the Moon spectrum
below for a camcorder demo (4Mo)
first in normal light then in nightshot mode... the diffraction grating being just put in front of the lens ! Objects visible in the movie are the Moon and street lights. Note that the spectrum is oriented with the blue towards the luminous object ! This is usefull to know when you have many stars and spectra mixed in your images ... |
