Ngc 6164-65 sho

This is a Hubble palette version of the bipolar nebula NGC 6164-65. Just about everyone images this thing in RGB colours so I thought I would see how it looked in SHO. The total imaging time was about 16 hours.

Cheers

Steve

Thanks Peter. I wondered about the palette but it looked okay in the end.

Thanks Andy. I'm still experimenting with it so maybe I'll come up with something better.

Thanks Louie. I'm not sure - probably a mixture of gas and dust.

Of course - a stupid mistake on my part. I'm having a bad week.

The outer ring looks wonderful. The impression of many overlapping and three-dimensional blow-outs, where the shock front encounters places where it can escape freely. Reminiscent of brain coral, perhaps.

H-alpha is a specific deep red light with a wavelength of 656.28 nm and emitted when a hydrogen electron falls from the third to second lowest energy level. Interstellar dust is mostly carbon, silicon and oxygen and not made of isolated Hydrogen atoms, so does not emit any Ha. Sometimes Hydrogen can be mixed in with dust but it is the Hydrogen that is emitting the light if excited and not the dust, so a Ha image is showing the distribution of the free Hydrogen in the image and not the dust.

We do sometimes hear people describing H-alpha images as showing "lots of dust"... but they don't

Very nice Steve, you’ve managed to capture the full OIII ring which has some pretty faint parts. Nicely captured
