Jeff,
Glad to see it coming together!
A permanently mounted spectroscope...now that's dedication
I've got no idea what's happening in the top B&W image...
Assuming a wide slit it appears like a series of - something???
Is the camera aligned to the optical axis? Should the spectra be centred rather than from the edge (or has this been cropped?)
A series of shorter exposures and a gradually narrower slit might make things clearer..
(The bottom coloured spectrum shows the "ripple" in the absorption lines usually associated with the slit being misaligned to the grating)
Now the book is finished I hope to get back to observing myself ( if the clouds over here ever go away!!)
