We've had a few okay nights lately and I have just come inside after using my EAA set up. C9.25 at f/2.3, ASI174MM, Astronomik 642 BP IR filter.

 

Here are some 5 x live stacks of several Southern Galaxies. Image width is 1.2° - a little more than twice a full moon. I use Celestron's StarSense on a permanent EQ mount and the target is exactly dead center each time.

 

Click on thumbnails to see full detail.

 

In order...

 

NGC5128, Centaurus A, the famous radio source. It is ~10' in diameter and ~mag 7.0.

 

NGC4945. This edge-on spiral in Centaurus is visible through the Milky Way,  14' across.

 

NGC5236 (M83), face on spiral in Hydrus, diameter ~10' - a second post of this image.

 

Centaurus Galaxy Cluster. This one will take some study to appreciate. The elliptical galaxy in the center is NGC4709, the brighter elliptical to the right is NGC4696, the brightest in the cluster. There are over 100 galaxies in the cluster, over a dozen in addition to the two big elliptical galaxies can be picked out in this image as smudges of light.

Very nice pics. (I'm hoping to capture Centaurus A from here, when it reaches 14 degrees above the horizon on the meridian. Who knows if I'll succeed.)
