Newsflash from Palmia Observatory.
Amateur science can be coupled with amateur astronomy very easily with the low cost tools that are available now. The Palmia Observatory resident astronomer, George, has acquired a 100 lines/mm diffraction grating and analysis software from www.rspec-astro.com, for just a couple of hundred dollars. The first attempt at collecting a spectrum of a star was performed last night using the bright star Arcturus. The spectrum from the diffraction grating is shown below.
The respec software generates the spectrum plot shown in the pdf document. Look at the intensity peaks. Pretty neat!
The next step is to learn how to calibrate the spectrum plot in order to convert camera pixels into wavelengths.
Until next time,
