Hello,

Lupus3 is one of nine dust clouds located in the Scorpius Centauros OB association. The Lupus Clouds (Fernando Comerón ESO, Handbook of Star Forming Regions Vol.II 2008) are star forming regions. Lupus3 is dominated by the two Herbig Ae/BE Stars HR5999 and HR6000 which form the blue reflection nebula Bernes 149.
Also visible in the FOV is a small reflection nebula called GN 16.01.6 in the bottom right of the picture, just below the snake like dark nebula.

The pictures were taken on 05th , 06th, 08th and 09th of July in 2016 at Kiripotib Guest Farm in Namibia/Africa.

That's a lovely wide angle portrait of a blue reflection and its surroundings!

It seems probable that the two stars, HR 5999 and HR 6000 (easy designations to remember) were born out of the elongated dust lane where they are now located. At least the dust lane to the east (left) of them is very thick and dark, which seems just right for star formation.

Interestingly, even though much of the blue light that the stars emit is scattered in the blue reflection nebula, the brightest component, HR 6000, still has a negative B-V index, -0.071 ± 0.002 in Johnson, and a tad bluer in Tycho. That is even more remarkable in view of the fact that the star is classified as an A1/A2III star, too. The "III", which means an evolved star, seems very unlikely.

But stars classified as A1 or later do so very rarely have negative B-V indexes. This one does, and it's solidly negative, too, not -0.001 or something. How remarkable!

Canon 450D Modded
Focal Reducer 0,8
26 x 300
Total: 2 Horas e 10 Minutos
Processing: DSS + PixInsight + PS6

Visible in the southern hemisphere, this beautiful nebula is much photographed by amateur astrophotographers.

It is possible to observe it even to the naked eye, due to its intense brightness.

All its splendor is revealed with a binocular or astrophotography.
