Description

The Rho Ophiuchi region is incredibly colourful and includes a trove of delights. The prominent yellow orange star is the nearly-expired supergiant Antares, which is 550 light years away and belching out gas before its demise. To the right of Antares is the globular cluster, M4, which is 7,000 light years away, while in between it and Antares lies another globular cluster, NGC 6144, which is 33,000 light years away! The name Rho Ophiuchi refers to the blue cloud complex towards the top right of the image, which surrounds the Rho Ophiuchi star system - this cloud complex is just 427 light years away from us. Finally, one of my favourite parts of this region is the tendrils of dust that reach out towards the core of the Milky Way which is outside of this frame to the left.

A recent holiday in Mauritius allowed me to have another crack at this beautiful part of the sky, 4 years after my first attempt from the same country! I shot this on a beach in Pointe Aux Piments, having travelled with my equipment. The Rainbow Astro RST-135 lived up to its portable potential!

Thanks for looking!
