Description:
This huge cloud complex is the most colorful region in the summer sky. It consists of a Yellow, Blue, Red & Dark nebulae. The Yellow gas cloud is a reflection nebula due to expelling gases from the giant star Antares (the heart of the Scorpion constellation). The Blue nebulae are reflection nebulae also but they are surrounding young stars. While, Red nebulae are emission ones. This gas cloud is about 400 light years from Earth. The image is covering 10 x 15 degrees of the sky. It is taken by a camera lens not a telescope. Just for comparison, the Moon is covering only 0.5 degree of the sky. So, imagine how big is this region in the sky. Total exposure is 6 hours. Light subs 120 x 180sec over 3 nights, 20 Darks, 20 Flats and 50 Bias. Captured by ASIair. Processed in PI, PS & Topaz. Image taken from Bortle 4 scale dark sky
