NGC 1313 (also known as the Topsy Turvy Galaxy) is an isolated barred spiral galaxy with a diameter of about 50,000 light-years, or about half the size of the Milky Way. It's pretty weird-looking with an uneven shape and its axis of rotation is not exactly in its centre.
What is also interesting is the IFN throughout the field. It doesn't seem to feature in many of the pics on the web, but there are some that show it quite well and the structure is similar to my pic, so it's real.
I got 12 hrs exposure on this one, but probably some more colour would be needed to bring out the brownish hue of the IFN that I've noticed on some web images.

BTW, there is a reflection artifact just below the bright star, which I've ignored.
