Rings of Halos

[Ken Crawford]

There are many wonderful images of this amazing nebula including the new one by Martin and Bill.

Interestingly, my new image of this familiar object displays an outer structure that may not have been previously detected. Using a very narrow OIII filter (3nm), my instruments were able to capture a halo-like structure that is very faint but just visible after over 16 hours of exposure time. I have color mapped the OIII to blue and you can see its faint glow. I have also provided a super stretched and enhanced black and white image with very high contrast to better reveal its structures. The outer structures are currently being examined by a professional from the Canary Islands.

Hi Ken,

Wow 16 hours! I just checked out your images and details, a lot of time and processing just amazing!

Cheers,

Hi Ken,
that's a great image & shows the power of narrow band filters to reveal detail.
The shells are interesting - I wonder what causes the gas to clump together like that?

[Ken Crawford]

Thanks!

It may be as this like many other PN is most likely a bipolar outflow. Will know more after it has been studies a bit.

Outstanding Ken, this is a great example of how advanced amateurs can do science :thumbsup: Congratulation on finding something new of one of (supposed) most known objects of the sky!

Thanks for all the kind words - yes go deep and then stretch the tar out of the data and see what's there :)

That's rather wowy Ken :thumbsup:

How did you decide on the shade of magenta/pink you settled on for the main rings?

Interesting about the OIII too.

Amazing Ken! After what seems like a lifetime of looking at the Ring, you come along and find something new. This opens up a whole bunch of possibilities for So. Hemisphere planetaries, or any planetary Wolf-Rayet object for that matter.

Hello Mike, great to hear from you . . .

The magenta/pink is the result of the strong OIII componet mapped to blue (and a bit of green) plus the Red of Ha = Magenta. The Strong SII componet was also shifted slightly to the Orange for a bit of transitional color.

Wow, ultra violent look. Not what I wa expecting at all. Love the detail and the general colour scheme.
