The width of the Heart Nebula is about 200 light years. That corresponds to 3000 pixels in this image. One light year is then fifteen pixels. Our solar system, out to Neptunes orbit, would make up only 0,014 pixel in this image.

This image consists of only two hours of integration time, including twenty minutes of luminosity. These are far too short integration times for narrow-band sub-exposures. That is why this image is very noisy, - with distinct graininess at full resolution.
