Description

Hi,

An other picture from my journey in Les Cévennes.

This was my main project, a 5 tiles mosaic from M16 to M8.

A7S modified, TS Star 71 mounted on the Lightrack.

For each tile, 210-230 x 30 sec subs at 3200 ISO. Taken in several nights.

Preprocessing with Astro Pixel Processor.

Processing with Pixinsight.

Final picture at 75%.

I have to admit, shooting from a dark place change everything.

So I'm very satisfied with this result, and I really have to try to shoot from dark places more often.

Version B : very slight adjustment of the white balance ; it's subtle, but I think it's fine now. Let me know if you think it is, or not ;-)

Cheers.

David.
