I'm still looking to "upgrade" my spectroscope, if anyone has or knows of an older used ( condition of grating doesn't matter) spectroscope available for sale can they PM me.
Hi,
I have one here available screws into a 1 1/4 " eyepiece from memory it was by Spectral Optics, Illl dig it out and let you know the details if this is what you are after.
