Lunar Eclipse Monday September 28th

John (Bruno),

Thanks for pointing this out. I didn't realize that their is some Nitrogen Dioxide (NiO2) spikes showing up either side of Ca ll at 4000 Angstroms. You can see some small spikes from 3900 to 4200 Angstroms. I was surprised that I detected this NiO2 considering the size of telescope/spectrograph.

I suspect that NiO2 may have shown up in other parts of the spectrum, in particular the IR.
However, my camera wasn't sensitive to that part of the spectrum.

I suppose these spikes are the man made pollution ones.

I was fascinated by your lunar spectra image.
Have you any images of your set up for taking spectra?

In the spectra graph, what does the CaII peaks mean?

Because I thought the composition for LIFE would be H20, O2, CH4, CO2?

At the rear of the telescope is a fibre optic cable inserted into the focuser.
The fibre feed takes the light to the small spectrograph to the right of the OTA.
The fibre end is inserted into one end of the spectrograph. The other end the spectra
is displayed onto a Nikon D700 camera.(not shown)

The spectra recorded a detection of the Ionosphere: CaII, (Mg, Fe??)
