Rho Ophiuchi cloud complex

25,002.500,00 (IVA tax inc.)


Rho Ophiuchi cloud complex is a close and active star forming region located in the constellation of Ophiuchus. It is mainly composed of gas and dust and hosts several amazing colorful nebulae.

This region is located some 460 light-years away from Earth.

It’s been a very difficult target due to its low altitude on the south horizon from my home observatory (at a latitude of 40º north).

The image has been captured using R, G, B and Luminance filters, to compose a two pane mosaic that aimed to capture an interesting part of this complex.

Once purchased, you have 24 hours to download the photo. You will receive an email with the download link.

Support my work. If you want to help me continue with my work, please feel free to buy, just for a few pennies, one or several of my images. The price does not reflect the amount of effort involved in each one of the images. Some of them implied weeks, months and even years of hard work. With your purchase I will be able to continue capturing photons of our amazing universe.
