Solar Spectrum, 5880A-6220A

January 13, 2013 – 12:37 PM

  The last several posts regarding spectroscopy have been about building the L-200, Calibrating the spectrometer, and so on.  Now, the time was here to use it on something other than reference lamps.   Being as careful as I am, I wanted to start easy, without attachment to the telescope.  That means a solar spectrum.  […]

Adjusting the Slit Width

The adjustable slit for my Spectra L-200 arrived last week.  Very happy to see it as the slit width on the temporary (the SS slit was on backorder) was too wide and I didn’t really want to mess with it. I thought I had a great idea. Use a spectral line from the Neon reference […]

Calibrating the Micrometer on my Spectra L-200

November 18, 2012 – 7:38 PM

  I finally have gotten some time to do some more testing on my Spectra L200.  I am almost ready to star test the spectroscope – just a few more rainy day activities left! The design of a Littrow spectroscope requires the grating to actually rotate.  This rotation puts different parts of the spectrum into […]
