Lion Nebula
Lion Nebula (Sh2-132) taken from Staffordshire, UK by Nigel Armitage in November 2025.
Sh2-132, also called the Lion Nebula is an faint emission nebula located in the constellation of Cepheus.
It can be found on the southern edge of the constellation, near the border with Lizard, along the plane of the Milky Way.
It is about 10.400 light-years from Earth, placing it within the Perseus Arm, in the region of Cepheus OB1, it is about 250 light years in diameter.
The stars responsible for ionizing its gases are very hot and massive, in particular, two Wolf-Rayet stars which are 50 times larger than our sun, but 1 million times brighter.
This is one of my more recent pieces of work and contains 140 images, 4.6 hours of data.
It was taken in a Bortle 5 Sky.
The equipment used was:
Williams Optics FLT132
ASI ZWO240MC Pro OSC
Optilong L Extreem Filter
ZWO AM5
ASIAir Plus
Williams Optics 50mm Guide Scope
ASI ZWO 120mm Mini Guide Camera.
The image was processed using Pixinsight and Photoshop.
