Explanation: What will become of our Sun? The first hint of our Sun's future was discovered inadvertently in 1764. At that time, Charles Messier was compiling a list of diffuse objects not to be confused with comets. The 27th object on Messier's list, now known as M27 or the Dumbbell Nebula, is a planetary nebula, one of the brightest planetary nebulae on the sky -- and visible toward the constellation of the Fox (Vulpecula) with binoculars. It takes light about 1000 years to reach us from M27, featured here in colors emitted by hydrogen and oxygen. We now know that in about 6 billion years, our Sun will shed its outer gases into a planetary nebula like M27, while its remaining center will become an X-ray hot white dwarf star. Understanding the physics and significance of M27 was well beyond 18th century science, though. Even today, many things remain mysterious about planetary nebulas, including how their intricate shapes are created.

The “Black Ho” is only “PUTAtively” black. I think her mother was listed on her BC as Caucasian, and her father as Jamaican. (She is a Jamaican citizen by descent under the Jamaican Constitution, and since both parents were Non Citizens here on Student Visas, may not even be a U.S. Citizen.)

Slide over.

M.C. Thank you for posting this beautiful colorful image!

I found this about how they processed the image, I did not realize all the work and changes put into it!

"Image Acquisition Information

Telescope: 16" RCOS Richey Chretien Telescope (ion milled at f/9) Camera: ZWO Full Frame Back Illuminated CMOS ASI 6200 MM Guiding: Starlight Xpress AO with UltraStar Autoguiding Camera (AO control using maxim DL software). Filters: Astrodon LRBG, H-alpha, S-II and OIII Filters Acquisition Programs: The SkyX, CCDAutopilot 5, FocusMax, Maxim DL Processing Programs: CCDStack, Photoshop CS4, PixInsight Date: Data processed July 4, 2021. Data acquisition: April 23, 2021-July 2, 2021 Time: 7 x10 min = 1.1 hour) for each of L,R,G,B and Ha for a total of 7.7 hours.

Image Information: NGC 5457 is a planetary nebula in Vulpecula.

Processing Information This LRGB images were obtained using AstroDon filters. The LRGB and Ha/S-II/OIII images were assembled in CCDStack. The assembled image and a Luminance were recombined in Photoshop. Further stretching, high pass filtering and background smoothing was performed with Adobe Photoshop CS/4 and PixInsight All data stretching was by without DDP CCD Stack and then further stretching . "

Here it is in black and white

Have to say, I prefer the color enhanced version with all the Photoshop rendering.
