About this image

LTNF 1 is an extremely faint and rarely-imaged highly-evolved planetary nebula in the constellation Ursa Major. It is a high-excitation nebula with an eclipsing binary star system (BE Ursae Majoris) at its centre which has resulted in its unusual morphology. It is around 5,000 light years from Earth. It is so transparent that galaxies can be seen through it. It was discovered by James Liebert, Richard Tweedy, Ralf Napiwotzki and Michael Fulbright in 1995. A joint project with Sven Eklund.
