Hi
I found this program many years ago on making a spectroscope. It involves using a SCT telescope with a diffraction grating printed on overhead projector film with a laser printer (I made one with a HP5M printer). I think it was originally on the Meade web site as an application to be used with the Pictor 416 CCD camera.

I don't know if it will run on later computers but I used Windows 98SE about 12 years ago to test the program and look at the test spectra. I never used it to take a spectrum because I never had a camera at the time.

The program is shareware and there may be later versions. I have never checked.

PS I was given a small handheld spectroscope on permanent loan that could be used for chemical analysis
