IFN is very elusive nebula that glows with the combined light of the stars of the Milky Way reflected and re-emitted by interstellar gas and dust. The IFN consists of blue starlight scattered by interstellar dust, as well as red light emitted by interstellar atoms and molecules. The IFN is so elusive it was not identified until the early 1990s. With modern equipment and fast telescopes, however, the IFN is within reach of amateur astronomers with moderate equipment like me - Canon 450D and 135mm f/4 telephoto lens. However dark sky is required and it is priceless.

After downsizing the picture the IFN can be revealed with higher contrast:
So, literally, everywhere you point the telescope, there is always something :)
