Ngc 4731

[TR (Terry)]

Here's another galaxy twisted by gravitational forces. The galaxy in the centre is NGC 7431. A barred spiral galaxy some 65 million years away near the Virgo supercluster. The colours come through fairly well showing the lovely blues where young stars are present in the arms. This galaxy is similar in size, but just a little smaller than our own galaxy, The Milky Way.

Instruments:

• Telescope: 10" Ritchey-Chrétien RCOS
• Camera: SBIG STL-11000 Mono
• Mount: Astro-Physics AP-900
• Focal Length: 2310.00 mm
• Pixel size: 9.00 um
• Resolution: 0.82 arcsec/pix

Exposure Details:

• Red 20X600 Bin1
• Green 12X600 Bin1
• Blue 18X600 Bin1
• Lum 48X600 Bin1

• Total Exposure: 16.33 Hours

Thanks for looking…

Ah the galaxy that doesn't quite know what sort of galaxy it wants to be nice one Terry

That's a very tidy image....and testimony to the skilled use of older, but very high quality gear that still works supremely well.

I'm beginning to think CCD based cameras have a cleaner/tighter look that CMOS has yet to deliver. I guess time will tell.

It's also refreshing to see a deep and accurately assembled LRGB palette.
(I am growing weary of seeing so many random and often garish NB palettes)

Really well done

That's a terrific galaxy image Terry.

I tend to agree with Peter here. I wouldn't be selling my CCD gear just yet.

Greg.

Fine image
It's good to see a deep rendition of this somewhat enigmatic galaxy.

That the best kind. We don't want normal . Cheers.

Thanks Peter. I do like LRGB.

Thanks Greg. A large pixel Full Frame CMOS would be killer expensive. I love large pixels.

Thank you Markas. It's a funky looking galaxy. I love the flattened arms.

Once again Terry, a wonderful, natural looking image, and look and all the faint fuzzies to the right!

Thanks Josh. I think that's the best part. I love that stuff.

Beautifully captured and processed. Really lovely result!!

Nice picture Terry,
you imaged a bound galaxy pair.
Well done.

Translated from here:
https://de.wikipedia.org/wiki/PGC_43526

LEDA/PGC 43526 (also NGC 4731A)
is a Hubble-type irregular galaxy in the constellation Virgo on the ecliptic.
It is estimated to be 63 million light-years from the Milky Way
and about 35,000 light-years across.[2]
Together with NGC 4731, it forms the bound galaxy pair Holm 472.

Cheers, That is a strange-looking object indeed. Being twisted in this part of the sky is the norm.
