Starship Asterisk*

I was struck by my ability to recognize things... Bernard's Loop, and M42 and Orion, and to the right...Taurus, and the very noticeable M45. I wondered what they were...then zoomed in... great.
Especially notable are the red hydrogen areas.

Really great image...

Does not the Dark Sky program mandate sodium lights? Is not the nearby light pollution attenuated or eliminated by sodium filters?

A lot of that light is not so nearby. And more and more of those cities are converting to LED lighting.

Sodium filters are more likely to be used by visual observers, which isn't much of a thing at Pic du Midi. Most imaging these days involves narrowband filters, which generally mitigate the impact of a lot of light pollution sources, both low pressure gas as well as most LED lighting systems.

I do remember this observatory fondly because of a little known program that appeared when the series 10 OS was introduced on the mac.
For the life of me, I can't remember its name or author, but he was rather famous for creating the simulated waves in large-scale hollywood productions.
He did it as an exercise, and didn't upgrade it. So it didn't last long as the OS versions changed.
But the background was this observatory (minus the tower) and the scenery was gorgeous.

BTW - the last sentence might read better in english if it said "...no longer fading star..."

Can't say I ever remember Orion looking so far away! :shock:
Nice photo anyhow! 8-)

Great panoramic picture. It should be interesting to compare this nightscape with the panorama profile generated by Peakfinder:
