Rho Ophiuchi
This part of the sky is one of the most colourful region in the sky. This area is about 4.5 x 6.5 degrees across the sky and lies between Ophiuchus & Scorpius constellations. This complex nebulosity cloud is composed of dust & gases that can produce 3,000 suns of our solar system. It consists of one of the closest star forming clouds and lies about 460ly from the Earth. It contains many celestial objects like large star clusters M4 and small star cluster NGC 6144. The yellow-brown star is Antares, which is a super giant star near its end of life. The yellowish cloud around Antares is caused by puffing star’s material to the space. The dark lanes in the image are dark nebulae that hide the stars behind it. I planned to image this beautiful part of the sky by two different lenses. The first one was taken by Canon 100mm f/2.8 camera lens for a wide view of the region and the second one for close-up view was taken by Redcat51 f/4.9. Actually, the close-up image revealed a lot of details of the complex cloud. For both images ZWO ASI 2600MC cooled @ -10 degree. The image subs are 180 sec exposure and the total integration for both images are around 1 hr, 20 Darks, 20 Bias and 20 Flats. Gear setup: iOptron SkyGuider pro unguided, ASIair, Baader UHC-S 2” Filter. Images processed by PS 2020 CC.
