Popping the Bubble Nebula!
Perhaps the last DSO session for the spring season. Let's make it pop!
I imaged the Bubble nebula a few years ago, with the old Nikon D7000 DSLR, about the same time of the year. Sounds just right to pay it another visit. This time with new kit, and hopefully some experience.
The bubble nebula is a Ha rich region in Cassiopeia where the solar wind from a hot, young star, SAO20575, is pushing out a cloud of molecular gas like a shell around it. The star is also heating the gas so that it starts emitting light, forming a emission nebula.
