Messier 57
2/08/2005
The past weekend was an imaging bonanza!
I imaged more in the past weekend than I believe I have in the past 2 years. I’m continuing to work my way through the Messier List – geeze there are a ton of star clusters in that catalog. I managed to capture 5 more objects, 4 globulars and a nebula. Tonight I processed M57, the lone object that wasn’t a globular.
M57 the famous Ring Nebula in Lyra is thought of as a benchmark example of a planetary nebula. It was discovered by Antoine Darquier de Pellepoix in 1779 and lies some 2,300 light years from Earth.
I captured M57 using a 12.5 inch f/9 RCOS Ritchey-Chrétien telescope with an SBIG ST10XME and AO7. The image is a combination of 6 – 10 minute exposures.
