NGC 4696 and friends

Hi all,

Here some imaging I did before the moon became a pain.

NGC 4696 is an eliptical galaxy in the Centaurus constellation (to the right of centre) 124Mlyr from Earth with a mag from 10.7 to 11.5, in total there is 35 galaxies in this image.
There was more but had to crop due to dithering, I might've done 300 sec subs more than likely was more, not sure how many as the remote obs lappy is having a sleep atm.

Thanks for looking.

Karl

a very pleasing image Karl.
It blows me away looking at images such as yours... you can assume that each of those tiny galaxies are about 100 light years across and separated by an equally mind numbing distance...

Thanks Alex,

It always amazes me the distance that separates them from each other but also the distance from us and that we are seeing back in time. The more I study astronomy the more I want to know. Soon to be getting a cooled camera for narrowband imaging.

Great image !!
Really makes you think how incredibly small but important our dinky little planet is when you see images like this and understand the endless enormity of the universe
By the way I cant remember what scope and mount your using now ?

There are a fair number of galaxies in that field, nicely captured

Thanks Martin and Colin, I counted 35 in the image, could be more fainter ones, next will be a 2x3 mosaic of that area.

Know this...no matter how many you capture there will be thousands in that field of view...perhaps billions and more likely trillions...we have a limit but in reality one must realise that if you could look forever there are presumably an infinite number ..if our limit was not constricted by expansion..after all it is reasonable to speculate the universe is infinite.

Very nice image Karl, I can see quite a few there. What reducer do you use for your RC?

I use a CCDT67 for my RC, it works well depending on what spacing I want to use. No spacing atm which gives me a focal length of 1231mm @ f6.2, spacer on gives me 1064mm @ f5.3.
