This pair of gravitationally interacting galaxies is located in the southern constellation of Eridanus (the River). They are outlying members of the Fornax Cluster of galaxies.
They are so close to one another that gravitational forces have distorted one of the spiral arms of the larger galaxy, NGC 1532. These forces have triggered bursts of star formation in both galaxies, but more so in NGC 1532 where a new generation of massive stars have been created.
NGC 1532, also known as Haley's Coronet is a nearly edge-on deformed barred spiral galaxy about 180 thousand light-years across. It is laced with incredible dust lanes, making this a dramatic target to image. It is receding from us at about 1040 kilometres per second. NGC 1531 is a dwarf technically classified as a peculiar lenticular galaxy; the galaxy's structure is better described as amorphous.
A good result Terry, nice, looks familiar too I've been hanging to shoot this one myself, it's such a weird but interesting shape, doesn't quite know if it wants to be an ege on galaxy or not ... but big and bright.

Cheers Mike. It's a very cool object. I love how that arm is being pulled up from the other galaxies. Interacting galaxies are one of my favourite objects. Makes me feel like a cosmic train wreck investigator.
This galaxy is an APOD for 28th July 2023, taken with the Dark Energy Camera mounted on the National Science Foundation’s Blanco 4-meter Telescope at Cerro Tololo Inter-American Observatory in Chile.
I'm not into imaging galaxies much myself due to the equipment and skill required, but I can really appreciate the detail and depth of this.
Many thanks Pete.

improvements? - I'm not sure -
could the saturation be increased a little more? -
it's a little washed out compared to other images I can find.
cheers

Thank you for your comments Allan. We all attack datasets differently simply because personal tastes vary from person to person. Some are into super-saturated images and bold pallets, and others are not.

Thanks Peter, this colour stuff is tricky.

Many thanks Peter. I believe that upping the saturation would take away what I am trying to portray in the image.

The best rendition I have seen of this one. The detail is stunning.

Thanks Greg

This is absolutely exquisite. an amazing rendition of an equally amazing DSO. Now i need to work how (or if) I can try to capture it with my own setup.
