Good morning, Rallypoint. Today's Astronomy Picture of the Day (APOD) is titled "M27: The Dumbbell Nebula." M27 (Messier 27) is also known as the Apple Core Nebula, and lies 1360 light years distant in the constellation Vulpecula (The Fox). Both lie roughly in the center of the Summer Triangle asterism formed by the constellations Cygnus (The Swan), Lyra (The Lyre), and Aquila (The Eagle). It was first discovered by Charles Messier in 1764.
When any notes are available from the astrophotographer, I like to share them with you. So here they are:
Telescope: 16" RCOS Richey Chretien Telescope (ion milled at f/9)
Camera: ZWO Full Frame Back Illuminated CMOS ASI 6200 MM
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.

The French for dumbbell is haltère which sounds more appealing to me; but; may well offend Dumb and Dumber actors :-)
APOD background
"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."
