Here's NGC 3313. I didn't have much colour data to work with

This wonderful galaxy is located in the Hydra Cluster. It presents a relatively small target some 181 million light years from us. Even though it is a large galaxy some 130 light years across, at this distance, it has an apparent size (v) 3.9 × 3.2[1]. It is a reasonably dim target, with a surface brightness is 23.4 mag/arcsec2.
Getting your head around these distances is incredible and challenging. For context, non-bird dinosaurs lived around 230-66 million years ago. It is mind-blowing that the light used to compose this image left this galaxy during the time of the dinosaurs on our planet. Yep, time machines are fantastic.
I love how this galaxy hangs against the background of stars and dust. The well-defined, thick ropey arms are the most interesting feature to my eye. Within these arms, two weak dust lanes can be seen in the bar of the galaxy.
