Two Quite Different Aging Stars
This image includes two aging stars approaching the end of their lives. NGC 6888 is the bright Crescent Nebula at the top right which is energized by a Wolf-Rayet star (WR 136), a massive star which will end its life in a supernova. At the lower left you can see the Soap Bubble Nebula (PN Ju 1), a planetary nebula of a much smaller star, shedding layers as it nears the end of a much longer life. This planetary nebula was first discovered by amateur astronomers in July 2009.
The image was captured with 10.5 hours of exposures with a AT115EDT, the ASI2600MC, and the Antila ALP-T dual narrowband filter, using the CEM40, ASAIR+, and ASI OAG, with the ASI174mm mini for guiding. It was processed using APP and PS.
