Messier 3, SBIG ST-4000XCM, 14x600sec,Darks/Flats/Bias Applied,Imager Temp -20C,Celestron 9.25 Reduced 0.63,20% Crop. Messier 3 (also known as M3 or NGC 5272) is a globular cluster in the constellation Canes Venatici. It was discovered by Charles Messier in 1764, and resolved into stars by William Herschel around 1784. This cluster is one of the largest and brightest, and is made up of around 500,000 stars. It is located at a distance of about 33,900 light-years away from Earth. Globular cluster M3 is extremely rich in variable stars: By 1978, 212 variables have been found, 186 periods determined, more than in every other globular cluster in our Milky Way galaxy.
