New HM spectroscope

Hi All,
I have nearly finished my model of the BAA spectroscope -1st image.
As a test I pointed it at an energy saving lightglobe, found the zero image and then moved the offset mirror to find some lines. I have no idea what they are, as I have yet to callibrate the instrument.

The image quality is poor and unfocused because it is the very first image. The camera was an old DSI.
However, it gives me enough encouragement to carry on.
Note the Diffraction grating should give adjustable dispersions and hopefully greater resolution.
