I'm not sure about the image quality (could possibly be due to it being a test run), but the main point of Herschel is that it images in infrared
Because infrared isn't obscured as much by gas/dust it means that the telescope can see deeper into the centre of galaxies at objects that are
generally difficult to see in other wavelengths.
And you probably wouldn't be able to take these kinds of pictures from your backgarden as the atmosphere absorbs a lot of the incoming infrared
radiation, plus the background noise from pretty much everything around you would be horrific
