Helix Nebula with an Oiii twist

[DJT]

When you look at Helix in just Oiii its interesting how different the photons are splattered about in a sunburst pattern when compared to how the Ha appears. This is then a view of the construction of NGC7293 in bicolour but processed with a focus on keeping Oiii visible. Noisy as buggery, really not enough Oiii data but enough to get the drift I hope.

Thanks for looking

Nicely done David, it is hard to keep the OIII features visible at the same time as show the intricate Ha detail but you have done a commendable job here :thumbsup: The less well known OIII details are pretty cool huh?

Nice one David. The Oiii channel looks like an explosion. :thumbsup:

Thanks for the comments gents. Was interesting just working through the Oiii data as I hadn't seen it before. Its weird the way the Planetary nebulas work and I can see why the long focal length appeal as they are all different.

Very nice, David.

I agree that there's a place for showing just the OIII on some objects. You've motivated me to get cracking and show an OIII-only NGC 602 that I've been struggling with.

Best,
Mike

Nice work, David. It's a tricky balancing act. Shame the Oiii in the Helix isn't brighter and hence less noisy :)
