Image Description and Details :

It took me 2 months to acquire enough lights to make anything out of it.

Indeed, I shot 14 winter nights between November and January (5 of which played with my nerves with the fog lifting at nightfall without being able to do anything).

So I shot from the Vosges, I camped in 0 ° C in Alsace, I shot from my astrobro Christope in Moselle, I went south of France to Valensole and I moved on several spots on several nights in this region.A total of 3,600 km of road to acquire the 55 hours of lights retained which consist of:

Tile 1:
Ha -> 71x600 ’’
Oiii -> 78x600 ’’
R G B -> 90x10 '' per filter

Tile 2:Ha -> 94x600 ’’
Oiii -> 78x600 ’’
R G B -> 90x10 '' per filter

While the acquisition was long and complex, so was the processing, I had to work with 400GB of data for a final image of 15 000 x 12 000px.Suffice to say that the PC has smoked!
Once again a big thanks to Christophe who illuminated me with his advices during the processing and gave me invaluable help, thanks also to Nico for his always correct eye!
