NGC5101, 5078 and about 100 other galaxies

[gregbradley]

Another galaxy cluster image I took last weekend at my dark site.

The top half of the image shows some yellowish background spots. These aren't stars and are all galaxies. There are a large number of them.

TEC180 and FLI ML8300, offaxis guiding.

LRGB 100 40 40 40.

Superb seeing. Sky was just totally still with stars even low on the horizon blinking only slightly. Stars near the zenith seemed totally still with just the very slightest shift noticeable on some of the brightest.
When its cold, seeing is often really really good at my dark site.

Great shot, Greg. Love 5101 and the dust lane on 5078...looks a little like a very "squashed and stretched" Cen A!!! :)

Really like this Greg, deep and timeless. Colours are also superb. Most inspirational!:thumbsup:

Wow Greg! What a great shot. Excellent processing too. :thumbsup:

Crikey you're on fire lately Greg! Leave some photons for the rest of us!
Another corker of an image - great detail and subtle colours and processing. Congrats on another keeper.

Wow Greg...

What an amazing photo!....both technically and artistically.


Thank you again.

Excuse me while I just pick my jaw up off the floor. Just one word, beautiful.

I feel like I am on a starship when I look at this shot! Wonderful!

That was a good observation by Mr "Renormalised" that
NGC 5078 resembles a squashed version of NGC 5128.

Both galaxies do contain a very prominent bulge or spheroidal component and both galaxies also contain a relatively small disk component (that is, a circular and planar component).
In the case of NGC5128, the inferred three-dimensional structure of its dust lane has proved that this disk component is actually a barred-spiral type of structure that is made of dust & interstellar gas & stars..... and that this approximately planar structure slices straight through the middle of the elliptical component.

However, the disk/planar component of NGC 5128 aligns exactly with its minor axis (the short axis of the ellipsoidal component), which is the usual case for dust-lane elliptical galaxies.
In contrast, NGC 5078, which is probably an type S0 galaxy, (or, alternatively, the "fence-sitting" S0/a galaxy type which is between an S0 galaxy and an Sa galaxy), has a disk component that aligns with its major axis (Long axis).

In both galaxies, the dust structures are not yet settled, and both galaxies have primary large-scale dust lanes that show strong evidence of bending or tilting (non-planar structures).

Nice work Greg!

bugger - thought i was the first to get this one ;) - then Was outclassed by Allan, then you come along with this shot - WOW!

Its an interesting galaxy. Worthy of a closeup by itself. I've imaged it by itself before but want to do another one with the CDK17.



Thank very much. The conditions were absoutely superb. Seeing at my site in the cold months can be amazingly good.



Thanks Marc. Processing is always a bit tricky to get the exact final result. Only thing I would change is shorter subs to control the bright stars. I think I will shift to 5 minute subs with this chip.



Hehe Rob. I've had a good run haven't I? I was stoked to get perfect round stars at my dark site using the MMOAG guider. Its rejuvenated using that scope for me.



Cheers Ross. I am glad you like it.



Thanks Keith. Its nice to know the hard work produces a good effect.



When all the conditions are right it is much like a window out of a spaceship looking at the objects closer up.



Thanks for the info. I see you are really into galaxies. That's good as you are a good source of education here.



Thanks Louie. And thanks for your tutorials. The inverted masks weren't in my routines but are now and are very handy at times.



Also Rich did an awesome one. That's what got me to do it. I wasn't aware these 2 galaxies were in the same field of view until I saw his image.
