Description

This was a bit of a processing adventure for me but I wanted to see how the NB turned out with the new PI mix I am using. That mix is 0.72 G and 0.88 B for the O-III that gives the Teal that is the correct color and 0.80 for the HA and R, since it is pure red. This keeps the colors proportionally in harmony. End result will depend on exposure length, filters etc etc, but the luminosity etc all can be manipulated.

From Wikipedia:

NGC 6302 (also known as the Bug Nebula, Butterfly Nebula, or Caldwell 69) is a bipolar planetary nebula in the constellation Scorpius. The structure in the nebula is among the most complex ever observed in planetary nebulae. The spectrum of NGC 6302 shows that its central star is one of the hottest stars known, with a surface temperature in excess of 250,000 degrees Celsius, implying that the star from which it formed must have been very large.

The central star, a white dwarf, was identified in 2009, using the upgraded Wide Field Camera 3 on board the Hubble Space Telescope.[7] The star has a current mass of around 0.64 solar masses. It is surrounded by a dense equatorial disc composed of gas and dust. This dense disc is postulated to have caused the star's outflows to form a bipolar structure[8] similar to an hourglass. This bipolar structure shows features such as ionization walls, knots and sharp edges to the lobes.
