First principles it is not, but people use the Seestar S50 roboscope with a distraction grating to get readings on the emission spectra of stars.

  Did you mean diffraction grating? Or is there something I haven't heard of? Frankly, distraction grating sounds like the perfect name for an amateur astronomy accessory.

    Alas, autocorrect. I really need the distraction grating to be something that distracts me before I buy more astronomy gear.
