Our second deep sky target, imaged from the remote observatory in Portugal by the AstroDarkTeam  composed of Stéphane Rolland and Pascal Gouraud.

Thanks again to the French Astro ARO team for the efficient and effective management of this superb site that hosts us.

We provide two versions :
This one in SHO + luminance made from the best of SHO images, and one in HSO. 

For this SHO version, 158 images of 15 minutes of exposure, for a total of 38 hours and 45 minutes. have been integrated. The selection of 158 poses was made on a total of 266 poses spread over 23 imaging nights, for a total of 40% of images rejected in order to preserve the best images. 

For the HSO  version, 193 images of 15 minutes of exposure, for a total of  48 hours and 20 minutes. have been integrated (50 HA 12h30 - 63 OIII 15h40 - 80 SII 20h).

A bit of history and science...
Discovered in 1892 by Maximilian Wolf, IC 405 or Flaming Star Nebula, (or alternatively SH 2-229 or Caldwell 31 in other object catalogs) is an emission and reflection nebula in the constellation Auriga, not very far from the open clusters M38 and M36 of the Messier catalogue.
This nebula located 1600 light years from Earth, has in the sky a maximum real size of about 5 light years. It surrounds a beautiful blue star AE Aurigae which is also an irregular variable star of apparent magnitude 6.This star has a atypical and interesting history.It is a young blue star of spectral type O, 20 times more massive than the Sun, 60,000 times more luminous and whose surface temperature exceeds 35,000° K.Typically, emission nebulae are illuminated by stars and collapsing gas clouds. This is not the case with IC 405 and its blue star AE Aurigae.
After analyzing its radial speed, this star has probably not been created within the nebula IC 405. Astronomers hypothesize that this star could have been thrown at high speed following the collision of two binary systems not far from the Great Orion Nebula (M42). AE Aurigae would therefore have traveled a long journey before coming to illuminate the clouds of hydrogen gas, oxygen and sulfur in the nebula IC 405 of Auriga Constellation.
This remains an unconfirmed theory, but depending on its speed and direction, this star will only pass through the nebula, but its passage has triggered shock waves as well as electromagnetic radiation capable of initiating the collapse of gas clouds of hydrogen in particular and to give birth to new stars.
These waves are easily visible in the photo in yellow/orange shades and the star AE Aurigae not far from the center also shines with a bluish halo.
The universe is truly amazing!. It is a source of ever-renewed beauty and of phenomena each more surprising than each other !.
