IPHASX J015624.9+652830 Astrobin Image Of The Day 11 September 2019
One of my favourite planetary nebulae - revisited with additional data and revised processing techniques. IPHASX J015624.9+652830 is a planetary nebula in the constellation Cassiopeia. It was initially discovered as part of the IPHAS survey. It was spectroscopically confirmed as a true planetary nebula by the professional astronomer Laurence Sabin in September 2011. It was also independently discovered by the French amateur astronomer Laurent Ferrero in 2013 and is also known as Fe 6. It is 212 arc seconds in diameter. I love the way it appears to be a translucent sphere suspended in space. It's spherical shape is slightly distorted. This, combined with the bright rim to the north east suggests some interaction with the interstellar medium. The small bright central blue progenitor star is clearly visible. The internal morphology also hints at it being a possible bipolar PN.
