It's been a while since I was last on here.
I have built a new modular DIY classical spectrometer (from plastic guttering parts ) which allows the potential to swap components about. Anyway here was first light on Jupiter taken 14th Nov. Most of the spectral lines are reflected sunlight, but there are also some methane bands.
Here's the uncorrected version of Jupiter
And here's the same with the continuum removed. You could barely see the Calcium lines where the UV response is so low.
Thanks for looking
