Interacting Galaxies in Eridanus

Interacting Galaxies in Eridanus

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 :question: :) 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 :P... but big and bright.

Very nice, awesome image.:thumbsup:

The hi-res version has an amazing 3D feel to it.:)

Cheers

Dennis

Amazing image and beautiful natural colour and detail. Great work!

[Mickoid]

Love this one Terry, top shelf stuff! :thumbsup:

[Peter Ward]

Very impressive.

By far the best work being posted currently on this forum.

Well done. :thumbsup:

[TR]

Thanks Dennis. :thumbsup:



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. :P

[TR]

Thanks Peter. It's an object that can only look nice. There is so much going on in that neighbourhood.


Cheers Mickoid. Arranging photos like a wine rack. Now that's a great idea. :)



Thank you very much Dave. Colour is always a challenge with this gig.

[Retrograde]

Wow - great image of a very interesting target.

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.

Excellent image Terry,
it's not often we see images as good as that here -

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

Wow what a dynamic looking galaxy.....beautifully process very well balanced colour....top job Terry

[PRejto]

Great work! Congratulations. Outstanding detail and colour. Personally I think the saturation is spot on...

[gregbradley]

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

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 think yours is better Terry.:)

Many thanks Pete.


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.


Thanks Greg


Dennis, your to kind, but thanks. I means a lot. :thumbsup:

[joshman]

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.

[markas]

Splendid resolution and colour rendition!
This is superb:thumbsup::thumbsup:

[willik]

Tops what a image beauty

[TR]

Cheers Markas. These guys helped to get me closer. :ship1: :lol:



Thanks willik. It's a very cool target indeed.

[Addos]

congrats on the iotd Terry, looks like you nailed it first time ;)


in all seriousness good capture and very well processed. many with a cdk17 couldnt have done better :)

[TR]

Thanks man. A 13 year old camera at the blinding speed of USB1, and a 17 year old scope with dirty mirrors :thumbs-up: Slow and steady.


Fortunately, it's not super small. Give it a bash.


Thanks Dennis. That means a lot.
