Solar Spectra @ 1.8A/pixel
Nothing too exciting, using the 135mm FL spectro with a 600 line per millimetre grating, 40 micron slit and the Canon 350 (un-modified). The resolution is about 1.8A/ pixel.
Shows a couple of things: Within two frames you can record all the spectrum from UV through to the far Red ;see how the responce of the 350 drops off in the red! and it also shows the slit was not square to the grating and the width ( 40micron) too large!
The graph has been corrected for the camera responce ( Vspec) and a few noticable lines marked.
Other than the slit ( now fixed!) the spectroscope works very well.
My headache from the beginning has been guiding..... I'm now on the MkIII beamsplitter design and still not there. Using a Rainbow/ Baader/Star Analyser transmission grating is 200% easier but the resolution suffers.
Anyway, thought I'd share........
