The Medusa Nebula, Abell 21173 viewsAt last some recent clear nights enabled me to complete imaging this object - in all it took 6 nights between clouds!
Located in Gemini, this large but faint planetary nebula was initially thought to be a supernova remnant. However, measurement of expansion velocities and the character of the radio emission confirmed it to be a planetary nebula.
Exposure: 9.7 hours total. DR
