SH2-116
(
Abell 71
)
SH2-116 is a small nebula that is also known as Abell 71 and sits not from the bright star Deneb in Cygnus. This object was first classified as a planetary nebula but recent studies show it to be an HII region instead. This object is best imaged using a larger telescope because of its size and some of the nice structure it has. However, SH2-115 is right next to it and a larger field of view can easily pick up both of them. The nebula surrounding SH2-116 is indeed part of SH2-115. The nebula does not respond well with normal RGB filters but you can use a red filter as a luminance if you do not have a H-Alpha filter. Using the hydrogen-alpha filter, you can easily pick up this object without exposing a very long time using a fast system. I exposed much longer to pick up the fainter SH2-115 around it.
