This image shows you a star filed around northern region of Antares in Scorpius with a span of about 5 degrees.
There is a vast dark nebula in this area, and very complicated reflection and ionized nebulae are tangled.
It can be said this field is one of the most colorful areas in the heavens.
A dark nebula near Antares is reflecting the Antares's light and we can see it as an orange-colored reflection nebula, has a number of IC4606.
And you can see a round bluish reflection nebula of IC4604 in upper side, is reflecting a blue light from rho Ophiuchi.
And one more, a reddish diffused nebula of Sh2-9 in right hand side is glittering by ionized hydrogen gas activated from the light of sigma Scorpii,
the mechanism of luminescence is different from that of former two nebulae.
