M 27, THE DUMBBELL NEBULA on 2023-08-13

This photo was done in my backyard in Kyle, Texas through a 6-inch Sky-Watcher f/4 Telescope, on a Sky-Watcher EQ6-R mount, using a ZWO ASI533MC PRO color camera. 72 subs x 180 sec. Plus an Optolong L Pro Light Polution Filter.

The Dumbbell Nebula (also known as the Apple Core Nebula, Messier 27, and NGC 6853) is a planetary nebula (nebulosity surrounding a white dwarf) in the constellation Vulpecula, about 1360 light-years from the Earth. The nebula is expanding at an angular rate of about 2.3 arcseconds per century. The age of the nebula is calculated to be about 14,600 years. The central star, a white dwarf progenitor, is estimated to have a radius which is 0.055 times the radius of our Sun, which gives it a size larger than most other known white dwarfs. The stars mass is estimated to be 0.56 times the mass of our Sun.
