Littrow Spectroscope Spectra-L200 by Ken Harrison manufactured by JTW Astronomy.
Spectroscope as pictured with three gratings: 300, 600, and 1200 lines/mm. The calibration light is Ne, and is powered by the new style circuit.
Un-used and in as new condition.
This spectroscope was purchased for a project and was not used because of a 9 month delay in delivery - I found another scope to borrow and then went remote... It has been sitting on my bookshelf because I couldn't bear to let it go :(
