Description

The 2 “big ones” are an unlikely pair:
On the left the “frayed” supernova remnant Sh2-221 (SNR 160.9+2.6), distance approx. 2.600LJ
On the right is the very large, approximately 600.000 year old planetary nebula Sh2-216, approximatelym 420 LY away. It was discovered in 1955 by Hugh M. Johnson.
The smaller objects from top to bottom: Sh2-217, Sh2-219 and LBN 755 are Ha/OIII emission nebulae.

The objects, also known as the “Auriga Quintet,” are all very faint nebulae.
