Description

During my mission to the C2PU observatory in november 2021, Serge Brunier was used to close the telescope before sunrise. He shooted the horsehead before dawn during 3 nights in pure LRGB.

We had a lot of reflection issues on the layers. But decided to process this horsehead anyway. Still a few reflections issues but I like it very much.

This is a (0.3L + 0.7R)RGB composition.

Hope you will like it.

Please, look at the full resolution ;)
