During our stay at the observatory, I had a little bit left at the end of the night after our collaboration, so I took the opportunity to take a walk in this dusty area of the sky that had been watching me for a while. I was able to shoot it properly during this moonless weekend.
I really wanted to highlight this epic fight scene between 4 dust monsters, LDN 1228, LBN 550, LBN 552 and LBN 555, that's why I went with this diagonal framing to make it look like one takes over in this battle.
I also wanted to respect the natural colors which I find really beautiful and which accentuate this duality with the bluish and orange hues like ice and fire.

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!

Image Description and Details : First "official" photo of our team Team Stellae Orientis Astrophotographie with the Perseus molecular cloud in LRGB by Yann SAINTY.

The Perseus molecular cloud contains the nebulae NGC1333 and IC348.

First lights on the fsq106 and the 2600MM and the result is up to my expectations. Combined with a bortle 4 sky this setup promises beautiful moments.

No moon so I wanted to image NGC1333 but seeing the beauty of IC348 next to it I could not resist the appeal of the mosaic despite the fact that it was not recommended during a first session with a new setup.

I imaged over 2 nights instead of 4 (lots of humidity and fog), which frustrates me in the sense that I only got half of the raws I wanted and so I had to shoot more processing. as desired, but you have to know how to have fun and try things!
