Added almost an hour of hydrogen sulfide during "nautical twilight" with a full Moon.
The goal was to test exactly this equipment setup.
The test was partially successful - in the middle of the session, there was an autofocus failure and a significant portion of the material went to the trash. On the remaining data, both sulfur and hydrogen-beta are visible, despite not the most favorable shooting conditions.

I haven't tried photographing bright stars.
And I don't plan to specifically, unless one happens to be in the field of view.
