Compliments of the season Bernard. Whilst not Zeiss, Joan Guarro Flo found great improvement in using a Richardson grating over the Thorlabs equivalent in his T_NOU echelle, so I imagine a Zeiss grating to be superior still, with the price tag to match no doubt!

We were graced with a beautiful lunar eclipse this week and I took the opportunity to record the filtering effect of the atmosphere on the solar spectrum. I used the LhiresIII with the 150l/mm grating on a C11, 314L+ was the imaging camera. I include a pre-eclipse ;) , and a mid-totality image too, ...

Superb results Joan. 16 bit CMOS spectroscopy has arrived!

A quick look in SIMBAD...

Matthieu,

Nice job, thank you for taking the time to document your method!
I have been using Anaconda on an Ubuntu laptop and had some success. Python is the way to go!
