Finally got the pick off mirror in the right position to allow imaging with the ToUcam. With a 100mm collimator/ camera and a narrow slit ( more on that in a moment!) managed to get my first images of the solar spectrum to check resolution etc.

The results exceeded all my expectations!!!! I'm actually getting 0.43 Angstoms/ pixel resolution!!!!!! I had to download the detailed specta from Kitt Peak to find a comparison. The Na lines are wide apart and you can see the Fe line between them. All this without even connecting it to the telescope, just bright sunlight into the slit.

The attached photo is a stacked 16 images, no corrections with the Kitt Peak comparison spectra just below. The Mg bands etc.

My effort with razor blades for the slit was so-so, it needs to be quite far into the 1 1/4 adaptor so the size of the "body" is limited to about 29mm diam. Need to find a better solution before the next trials.
