ETA Carina in NB Last image for FRED.

[Hagar]

I also managed to capture 3 Hrs of SII for my eta Carina nebula image.
In total this is 6.5 hrs total exposure.

I have created many variations of Eta in NB. Don't know which I like the best but I am interested to see what you think.

Captured with Atik 11002M and Baader NB filters.

Sorry I didn't mark which was which.
1 HST SII,Ha,OIII
2. Variation on shading HST
3. Reverse HST OIII,Ha,SII
4. CFHT Ha,OIII,SII
5. Ha,Ha,OIII60%,OIII100%

NICE ! I like #3.

[renormalised]

I like #4 best, then #3, then #1, then #2.

The images are a bit small to appreciate properly Doug. Flipping between them while they are not bad images none really grab me to be honest but this may just be because of their small size?

I think No3 may be getting close..?

Yep No 3 gets my vote too.
Appeals to the eye nicely & seems to bring out the detail more.

[Alchemy]

I think I prefer the red , but it needs a third color to balance it out.
Just my opinion as a personal preference, I may be outvoted but there you go

Added another which is really my choice.

Here is the HiRes version (http://www.darkskyau.com/cm/displayimage.php?pid=268&fullsize=1)

[Hagar]

Thanks for the comments Guy's. I am still having problems getting the detail and colour right with NB images but will eventually get it sorted out.

Hello Doug:
Wow, it's beautiful, either.
If I had to choose, would take the "green", which I suppose is the palette of HST.

Doug
Can appreciate your dilemma on the colour cast.
I had real troubles processing my NB M20 until Martin Pugh re-did my data and made a far more pleasant rendering of the object. I was too heavy handed and not used to it at all and wound up with some really fluorescent images and too garish for my taste.
His processing was really well done.

Top shot Doug. Really like it. Maybe you know it, maybe you don't so here's a PS tip to get rid of these blue halos around the stars (see attached). If you go to filter>noise>reduce noise then tweak the Reduce Color Noise slider so you can dim down the rings around the saturated stars and you'll bring them back to a whiter color. I use it all the time for NB shots as depending on the blend you use at the time you end up often with purple, green or cyan stars. Nice work. You're really churning them out lately. Good for you. :thumbsup:

Nice tip Marc

[spearo]

Yep
I was going to say I like the colors of the last but the stars of the second last.

Marc's solution is top notch
I've made a note of it myself to use in my images !
cheers

HiRes is super Doug

[Hagar]

Thanks for the tip Marc, Just tried it and it works a treat but it does seem to desaturate the stars a bit. I hope to get some RGB to replace the stars in the future.



It really works Allan.



Thanks Frank



Thanks Trevor.

Here is one for Fred. An almost starless version. My first attempt at this sort of thing. OHHHH not really sure about no stars.

Hi Res version: http://www.darkskyau.com/cm/displayimage.php?pid=269&fullsize=1

[TrevorW]

Interesting though, I, like you, are not too sure about no star renditions

[strongmanmike]

Because it is a wider field of view at least it is obviously an image of an astronomical object...looks rather dramatic actually.

[DavidU]

The Hi res starless one is the best I have seen from you Doug.
Corker !

[SkyViking]

I like the starless one too Doug, it really shows off the nebula well!
- And better to do one now before Eta blows up, then it's going to be difficult to make a 'starless' for a while :P :D

[Hagar]

Thanks Trevor Like the detail just short on stars.



Thanks Mike, it does make the detail look different.



Thanks David,



Thanks Rolf, Big bang that will be.

[Omaroo]

Love 'em Doug. Go nuts! :D

I have only an SII to buy yet... and I'm in this game as well. :thumbsup:

[Octane]

Doug,

phw0ar!

I really like each and every palette you have presented here. But, for me, from a purely artistic point of view, the green and gold in the third rendering is by far the most visually striking.

The starless version is also a brilliant work of art.

More!

Thanks Chris, NB imaging is quite interesting. The detail you can extract is something else but the colour schemes leave me wanting a bit more. I have come to like a blend of just Ha and OIII eg. HaHaOIIIOIII mapped as LRGB as the colour is not totally different from normal LRGB just more detail and a bit more striking in colour.
SII filters are a challenge at best and require an awful lot of exposure to produce results although the stars do pop on the SII better than the other filters.
Have fun Mate, I know I am.



Thanks H, I still have a way to go with processing NB images. The processing is again something different using NB filters but like anything we all improve with time.

[Hagar]

The last image is for Freds comment. Never tried this before and probably got it all wrong.

[Bassnut]

OOOh man, that is fantastic Doug, soo excellent, a classic, geez, soo smooth, the detail........ (hang on, I need a cleanex...........).

Doug, you have reached nirvana right there, cant believe it, APOD material, best image ive seen in a loooooong time :bowdown:

[Hagar]

Glad you liked it Fred, It was an interesting exercise producing the entire image and all the variations. It gave me a great insight into the possibilities of NB images and blends.
