Got the camera going last night, first time in quite a while.
Here's a narrowband ETA in tonemapped colour.
6 each S2:Ha:O3, 15minute subs.
Takahashi FS-102 @ F6.
added repo to fix sharpened stars and larger image. (http://starshed.net/gallery/displayimage.php?album=7&pid=92#top_display_media) Click image to enlarge.

Very funky, Robin! Nice to see something a bit different.

Nice photo & you did well to use
the complicated technique of tone mapping.
05-02-2012, 07:27 PM
Nice colours on that :thumbsup:

Love the colours, are u going to add more to it later ? Hope so.

great colours and fov

Just had a look at this method.
Can't say I'd subscribe to tone mapping as described above :question:....as it changes the data rather than enhances it.
I also don't agree that the SII data shows little information. It is often the most exciting...but needs exposure time & dilligence to capture, calibrate and enhance.

Love the colour but the stars are wrecked. Is that oversharpening or some consequence of the tone mapping?
05-02-2012, 09:53 PM
Cheers everyone. I was planning to have a look at the cone last night but after an hour odd it was obvious the moon was just too close to it. All the subs showed a hot spot in the middle of them and it just looked like a white blob :lol:
I haven't been following that tonemapping method as written. I remove the stars and give the 3 channels a severe stretch, no blur, but you have to be careful not to burn em out. Here's the tonemap from this image. I then used apply image in PS to add the O3 and S2 to the Ha, gave it a sharpen, and use that as a Lum for the tonemap. I normally use a mask to sharpen after combining everything but got sick of sitting at at keyboard on this one. The hubble colours come up on their own and no magenta stars to deal with :D
Some images seem to show more detail this way, others, including this one, don't look much different from the traditional method. I tonemapped this one as I lost control of the colours in the other one :P

Ya don't get away with much round here :)
Over smart sharpened I'd guess, I was too lazy to mask it this arvo. Did a repo :)

A great photo.
Amazing detail and sharpness.

Very nice, great processing, like the colors!

Nice work Robin, one of your best I think. The repro is much better.
This is now IOTW (http://www.iceinspace.com.au).
06-02-2012, 08:36 AM
Great stuff Robin
Wonderful colour and detail.
06-02-2012, 12:54 PM
The repro is wonderful Robin. Congrats on IOTW.

So much to learn!
Is Eta nebula visible without a filter?
06-02-2012, 04:08 PM
Robin that is very nice. Going to use it as my desktop for a while.
Seeing how good you guys are just makes me impatient to get my own astro-photo gear.
Thanks for showing us.

Congrats on your IOTW Robin! well deserved with some very nice work.
06-02-2012, 05:27 PM
Congrats on IOTW. Beautiful capture, love the colours ! :eyepop::thumbsup:
06-02-2012, 09:14 PM
Repro is incredible! Love the colours. I don't normally go for this palette but when it comes off, it's just smashing.
Richard Gamble - It sure is. You can see it as a bright knot in the Milkyway, just "above" the Southern Cross. Looks great in binoculars, especially from a dark site.

Thanks Cam....will try to observe it tonight, weather permitting.
06-02-2012, 09:29 PM
nice work and great result
07-02-2012, 09:27 AM
:D Congrats on IOTW Robin. Well deserved.
07-02-2012, 09:29 AM
Thanks everyone, that's the first time in a long time that I've captured enough data in a single night to make a complete NB image. It has been taking days and days to get enough data due to clouds. Being able to image till dawn seems to be a rare thing these days :(
09-02-2012, 02:46 PM
It's a learning curve this wavelength ordered palette thing..but it also allows for such freedom of expression. Your journey is moving along nicely Robin, great job :thumbsup:.
Yeah, great stuff Robin. You're leading the way with this NB stuff around Brissy now! :thumbsup:

Congrats on IOTW. Go the narrow band.:thumbsup:
12-02-2012, 08:31 AM
Great shot and a well deserved on your IOTW . Narrowband certainly produces some spectacular images :thumbsup:
12-02-2012, 01:06 PM
Cheers guys. I'm thinking focal length used can make as big a difference to the image as anything else. That tarantula I did last month (http://www.iceinspace.com.au/forum/showthread.php?t=85875) looked weird at 600mm while a lot of the images of it on line look fine with just the main nebula full frame and that's something you can't really see unless you shoot it and combine it.
Back to sleep now, it looks like clouds and rain for a week :(

Congratulations on IOTW!
I really, really love the starless version. What a beautiful work of art. The colours are just perfect. One to print out, mate!
12-02-2012, 03:34 PM
Nice colours not over the top well done
12-02-2012, 06:43 PM
Thanks guys, if the rain stops we can see if the RGB filters still work from 10chain hill next week-end :D
13-02-2012, 08:37 PM
Love it Robin, meant to comment on it a while ago.
Great palette choice as well....
All the best
