Ngc 1808

[TR]

Scottish astronomer James Dunlop first described this object as a "faint nebula". NGC 1808 is 35,000 light-years across and about 40 million light-years away. It is classified as a barred spiral galaxy (https://en.wikipedia.org/wiki/Barred_spiral_galaxy) in the constellation Columba located in the Southern Hemisphere. Bars are found in about two-thirds of spiral galaxies. NGC 1808 has an apparent size of 7′.41 × 3′.39 arcmin and an apparent magnitude of approximately 10.

When I combined the initial red, green, and blue filters to create the RGB colour component of this image, I was taken by how muted the colours were. Adding Ha into the mix helped to richen the colours a little more. The luminance data was a treat. For a relatively small target and modest-sized instrument of 10 inches, I was more than pleased to see the level of detail present. I love the prominent dust lanes.

The following link (https://noirlab.edu/public/images/iotw2320a/)shows a similar look to my initial colour combination. Once the Ha was added, it lifted the colour and hues within the galaxy. I have included the core in Ha below. I think it's very cool.

Hi Terry,
that's an excellent image on a difficult target.
I hope it gets another image of the day.

cheers

Ooo thats a bit good!....got to love that detail

[Peter Ward]

You are clearly on a roll.
Great data.
Thoughtful and nuanced processing.
What's not to like here? :thumbsup:

An excellent image Terry.

Greg.

[TR]

Thanks Allan


Cheers Peter, Thank you for the great feedback :thumbsup:


Thanks Peter, sometimes we get lucky and surprised with the result. This surprised me.


Thanks Greg

A well presented galaxy Terry with lots of interesting background galaxies to entertain as well :thumbsup:

[Dave882]

Great image again. Fantastic detail and those background fuzzies are wonderful!

[strongmanmike]

Love the fireworks eminating from near the core on this galaxy, looks pretty cool, another very nice result Tezza :thumbsup:

That's always a treat to see that stuff. Cheers


Thanks Dave. Love the tiny galaxies ;)


Thanks man. That's an interesting area. Looks like smoke rising from the core.

Splendid image! Colours are certainly dramatic. Wonderful!

Thanks Mark. I am always afraid of venturing too far into the realm of super-saturation. This is as far as I am willing to risk. :thumbs-up:
Cheers

What is not to like about this! Inky black smooth background, oodles of smooth background galaxies. Once again, not overly done and masterfully processed. Was the AOL in operation for this, Terry?

[TR]

Thanks Josh. No, the AOL faulted a few years back. The housing is still in place, I removed the internals so it is just a shell.

[Stephane]

A very cool capture this one. The fainter part of the galaxy is really nicely processed. And the background galaxies look great too!

[TR]

Thanks Stephane. I didn't find many renditions of this guy. My favourite part is the top faint arm as well.
Cheers,

[Paul Haese]

Lovely image Terry. Detail is especially nice.

[TR]

Thanks Paul

[Addos]

nice capture Terry. Good job on the decon / sharpening too - right to the limit without going over, well done :)

[RobF]

Wow, what a stunning image and so much action with the myriad of background galaxies in the zoomed (and wider) field.

[TR]

Cheers Addos

Thanks Rob
