Some stars explode in slow motion. Rare, massive Wolf-Rayet stars are so tumultuous and hot that they slowly disintegrating right before our telescopes. Glowing gas globs each typically over 30 times more massive than the Earth are being expelled by violent stellar winds. Wolf-Rayet star WR 124, visible near the above image center spanning six light years across, is thus creating the surrounding nebula known as M1-67. Details of why this star has been slowly blowing itself apart over the past 20,000 years remains a topic of research. WR 124 lies 15,000 light-years away towards the constellation of Sagitta. The fate of any given Wolf-Rayet star likely depends on how massive it is, but many are thought to end their lives with spectacular explosions such as supernovas or gamma-ray bursts.

This is a bright but small planetary nebula that reacts very well with H-Alpha, but you do not need to use a narrowband filter to get a nice color image of this object. Simply use LRGB filters. It is very small, and I would recommend using at lease a 1200mm Focal Length telescope. A very larger telescope should show some fine structure, and since it is fairly bright, should not require long imaging time.

This is a ring nebula surrounding the runaway Wolf Rayet star WR 124, also known as Merrill's star.
