Description

Lotr 5, short for Longmore-Tritton 5, is a large, faint planetary nebula in our Galaxy, about 1650 light-years away from us. It is one of the largest planetary nebulae known, with a radius of 1.8 light-years. It has the highest galactic latitude of any known planetary nebula, being only 1.5 degrees away from the galactic north pole.

NGC 4725 and NGC 4747 are two galaxies out of our Galaxy, about 41 million light-years away. The smaller distorted galaxy, NGC 4747, has extensive tidal tails, indicates strong gravitational interactions in its past. The larger galaxy, NGC 4725, appears to be a normal spiral galaxy at first glance, but it does look a little odd with only one main spiral arm.

To the right of NGC 4725, there is a smaller galaxy, NGC 4712, which is a distant background galaxy that has nothing to do with the pair of interacting galaxies and is more than 200 million light-years away.
