The Lion nebula is a far more complex and interesting region than I imagined when I first started researching it. It's not only a mesmerizing emission region, it's largely driven by two Wolf-Rayet systems, and this wide view also contains at least two small, but visually apparent, planetary nebulas. I actually shot this target a few days before I gathered this data, but then I realized I hadn't framed it with the planetary nebulas in mind. The Moravian C5 yields a crazy fov with the TOA at 990mm, so I restarted while attempting to get Abell 79 in the frame and turned the original shot into a tight crop of the central region.  Turns out that it's a pretty tight fit squeezing both Sh2-132 and Abell 79 into the frame, but I think this framing works okay.

As outlined in this closeup of the Lion, the central region of the Lion's head is dominated by the strange Wolf-Rayet 153ab. WR 153ab is actually a complex system comprising two binary-star pairs. WR 153ab lights up this entire region of Sh2-132, ionizing the nebula's gasses with its extreme stellar wind. The interior bubble around WR 153ab is expanding with a velocity as high as 100,000mph (36 to 45km/s) as a result of that radiation. The main star in WR 153ab is 60 times the size of the sun, has a surface temperature three times as hot, and is a whopping 5,000 times as bright as our little star.

The body of the Lion is, in turn, driven by another Wolf-Rayet star, WR 152, which is responsible for the large, deep blue oxygen-rich rings present in that area. Those rings are expanding as much as 50% faster than the bubble around WR 153ab. WR 152 has a similar surface temperature to WR 153ab. In the first revision, I've annotated the image showing the locations of these two Wolf-Rayet systems.

In the lower left corner of this image, you can find the galaxy-shaped Abell 79 planetary nebula, nicknamed "The 6 Nebula." The central star is a cool dwarf incapable of producing the observed ionization, so it's thought there is a hot companion that isn't visible. It could be that the interaction between these two stars is what produces the unusual shape. The second revision shows a close crop of Abell 79.

Near the center-right of the image is PN G101.5-00.6. I can't find much information about this planetary nebula, so all I can do is provide a close crop as the third revision.
