Blue Snow Ball NGC 7662

October 4, 2016

NGC 7662 used to be like our own Sun. After using all its nuclear fuel, it ended its life and spewed the elements inside it to its surrounding space.

Though it is bright, having a magnitude of around 8 (you can see the central part is over exposed ) it is however a small nebula, about 30 arcseconds in size. Here is an image from a website,

The area of this image is the size of the full moon. In the center of the image, the bright 'star' is this Nebula.. no detail can be seen at this magnification.

Luckily i have C14 and the above image is showing the complex details of the gases which were thrown out form the star in different times and in different angles. I was auto-guiding with both the mount and SBIG AO8 Adaptive Optics; guiding corrections were being applied few times a second. This is 

Of course whenever i image something, i look how Hubble Space Telescope saw it. This is how it is compared with my image. Hubble's image both optical (green) and Infrared (red) combined.
