Some data I had hanging around from last year. This is NGC6334 @ 2760mm focal length (Ceravolo 300 astrograph @ f/9) with an Apogee U16 camera. Approximately 8 hours of Ha, 9 hours of Oiii and a couple of hours of RGB through thick light pollution to attempt to get some star colour.
The Oiii is pretty dim so this is mostly a Ha image. It's probably a bit too colourful for some tastes. The RGB stars didn't work as well as I would have liked. Still, I think it's an interesting image

Sunglasses needed but you also get a thumbs up for being able to maintain the detail despite the image colour vibrancy. Really electrifying palette Rick. Dare I say it, its growing on me. Though, I would have liked to have seen more of the OIII emission coming through and maybe tone it down a little.
Its normally a dead boring object, just all red with very little interesting feature. But your colour scheme has livened it up. The yellow is showing lots of billowy detail there.

Thanks, Jase! There was very little Oiii unfortunately. I have noticed that in a couple of other narrowband images. Even Don Goldman couldn't dig up much of it I may yet tone it down a little more but you should have seen the original

Very similar to your Veil shot, a new (Ricks) world order..? Straight onto glass or ceramics mate, a work of art

Thanks, your Mikeness! You gotta push the boundaries occasionally
I'm expecting a couple of large Veil pics back from the framers this week.

No probs, David. I did go a little OTT and expected mixed reactions.

Thank you, Ross.

Greg.
Thanks, Greg. I was pretty happy with the detail. The chrominance mapping I did on the Ha is a nice trick but one that I could overuse if not careful. I may script it up so I can experiment easily with more subtle treatments.
Very fiery shot! Just out of curiosity what makes the yellow? A mix of Ha OIII or something else?
Thanks, Kevin. The yellow is from the brightest Ha emissions. Searching for a technique to make straight Ha look more interesting when I was processing the Veil nebula mosaic I experimented with using the luminance to modify hue. I do it manually in PI with a couple of slightly hairy PixelMath expressions but when I get a chance I will write a script to automate it and make it easier to experiment with the settings.
