HeCd laser
A rather uninspired image I know, but anyway, it shows the (IMHO) beautiful deep blue/violet 442nm light of a Helium Cadmium laser. Few of these lasers are manufactured anymore and they are a dying breed due to the wide availability of high quality diode pumped solid state lasers being able to produce nearly the same colors at far greater reliability and lower power consumption. This image is looking down a 50mW beam which has been expanded to a safe ~30cm. The company, Omnichrome, which made the laser, was acquired by Melles Griot in 1997.
hale bopp 6frames-scale-Edit
C/1995 O1 Hale-Bopp from Yosemite. i found the negatives from this trip and was able to stack 6 pictures together using deep sky stacker. unfortunately there were airplanes in 3 of the shots. this was shot on kodak royal gold 1000 using a pentax K-1000 and a prime-focus 50mm, f/2 lens. scanned with a nikon ls-50, processed in lightroom and noise reduced in noise ninja. i pumped the blues a little bit to get more definition in the tail.
