LoTr 5

The nebula, more commonly referred to as LoTr 5, short for Longmore-Tritton 5, was discovered in 1980 by AJ Longmore and SB Tritton, who found it on photo slabs taken at the Schmidt telescope in the UK.

This is a large and weak planetary nebula in the constellation of Chioma di Berenice, about 1,650 light years away

In 2018 it had the highest galactic latitude of any known planetary nebula, located only 1.5 degrees from the galactic North Pole.

LoTr 5 is one of the largest known planetary nebulae, with a radius of 1.8 light years, emits mainly light at a wavelength of 500.7 nm, corresponding to a double ionized oxygen line.

It is noted that LoTr 5's central system has been binary since 1983. At the centre is an evolutionary G-type star (IN Comae Berenices) which is often classified as a giant or subgiant star, as well as an O-type hot-white subnana or dwarf that is responsible for ionization of the nebula.
