Close examination of NGC 1365

strongmanmike (Michael) · #1 25-01-2010, 05:51 PM

I worked a bit more on just NGC 1365 from my wide field Fornax Galaxy Cluster image. I've extracted and highlighted a little more of the wonderful detail this galaxy displays. This galaxy has so much inside it it is well worth the probe I recon

The whole galaxy up close (450k)

The amazing intricate dust lane across the barred spiral (260k)

It is lots of fun working with such a wide field of view when the seeing was good, there is so much that can be extracted

Hello Mike,
I'm inpressive about your image. It is so beautiful and lot of detail in the galaxy. What is your setup for this image and the time ?

Mike I like the widefield nice colours and plenty of detail

Hi Francki

I see you are new to IIS, so welcome

I posted the wide field full frame image (that included this galaxy) here yesterday, this image of just NGC 1365 was cropped from the wide field full frame image.

You can see all the versions and crops of the original image here including details of the equipment used:

enjoy

You're a bit like myself mate.. Once you have some fresh data to play with you just Keeeppp on playing..

Lovely mate... The dust lane is magnificent...

Gotta run!! Got the scope all set up, ready to recommence imaging!!

wooooh!!

strongmanmike (Michael) · #6 25-01-2010, 08:04 PM

Ooops I posted the wrong versions - just re-uploaded the correct ones

Yeh it's so much fun, having such a large high resolution field to play with allows for so much versatility, I love it

Go for it mate...totally cloudy here

and it's a holiday tomorrow of course

Very impressive Mike, the detail is great. All those little Ha areas , dust areas and small star pockets shining brightly.
Great stuff, Hi res is an understatement. Imagine what you could do without an atmosphere to break through.

Lovely.

Great image of an interesting target which is too far south for me to see or image.

I also prefer shooting widefield with the flexibility of cropping targets for close up images.

Thanks for sharing!
Cheers

Mike,

Most impressed and especially like the close up of the dust.

I'd just be happy with a larger aperture and/or an observatory...

As long as your optics and mount are top notch to provide good enough tracking, field correction, image scale and resolution (1.6" is close to ideal really), yes it is the way to go, especially for time limited portable remote imaging like I am forced to do. As I said it is really great fun to have the flexibilty of being able to crop out parts of the image to make whole new ones

Yes it is hard to believe that a little 6" glass here on Earth can zoom in so tightly on something nearly 60 million light years away and reveal such details

I like this better than the wide field shot, does more justice to the main object in the image.

Fair enough, one can decern more detail in the close up crop of NGC 1365 than in the wide field full frame, that's for sure... but what "is" the main object in the full image? Is it the nearby spiral or the group of more distant massive eliptical galaxies..?

this was my resasoning for producing several crops and enlargements in the first place so each of the main aspects of the image can be showcased in their best light

As a viewer of your art(and what great art it is), the brightest, largest, best detailed object in the first third of your frame causes the eye to centre on that object and then rove over the rest of the frame, to come back to the said big shiny spot, making it(to me) the main object in the image. Nothing else in the image has the attraction potential like this does.
Is it known as the rule of thirds

or something like that?

Yes you are quite right, looking at the full frame image the eye first focuses on the bright NGC 1365 on the left then it seems to travel right and wander in a curved path around the yellow elliptical galaxies to end up back at NGC 1365...its pretty profound actually, hmmm nifty...

Probably why I keep coming back to this version of close crop too, it looks balanced becasue the group of bright stars to the right balance the view..?

Cheers for that, t'was an interesting exercise
