Strictly speaking, LHA 120-N44, also known as MCSNR J0523-6753 or simply N44, is the supernova remnant located just above left of the center of the image (see annotated image below). The fact is that this name has been used extensively for the whole nebula complex that can be seen in this image and many of the nebulosities around it have names accordingly.
This huge nebula is located in the Large Magellanic Cloud, a Milky Way satellite galaxy located 170,000 light years away. The image shown above includes many nebulosities that are very faint. The dynamic range of the photo has been compressed in order to depict even the faintest nebulosities that are rarely shown in images of this object. This image has been taken with narrowband filters: Hα, [OIII] and [SII] as well as short RGB exposures to capture the stars and it is the result of an ongoing joint imaging project between Christian Sasse and myself. In this web site, there is another, older, image of this nebula taken seven years back. This image, taken with another equipment (telescope/camera) can be found here.
