The Pillars of creation

[Emanuele]

Full moon is still out there...so here's M16 through a 24" RCOS and Apogee U42.


2x 11 minutes in Ha.
Calibrated and Registered in Maxim DL5.

Unfortunately I just realized that iWeb (the program I am using for my website) changes the colors slightly once I upload the jpgs. I am not sure why is that, but the dark areas are lighter once they go through iWeb)

That's absolutely spectacular. Great detail. How did you get them to lend you the Hubble?

Excellent shot Emmanuel - plenty of good detail here, very well done.

The colours is related to colour space, the 2 most popular are Adobe RGB and Adobe sRGB. Adobe RGB has a far wider colour gamut. For serious imaging, you'd usually use Adobe RGB for all the processing side, and if you're uploading to a website, then you'd convert the image to sRGB, since web will not display Adobe RGB (well, let me correct that comment, most web browsers will *not* support Adobe RGB). FireFox 3 does, but you have to turn the function on in one of the config entries (about:config in the address bar). You will notice some difference in colours between the 2 colour spaces.

As an aside, are you running a calibrated monitor? If not, I'd highly suggest doing so - it'll help set the black and white points for the monitor properly, as well as the contrast and gamma. It'll help ensure colour accuracy and consistency amongst your images.

Also, as a side note, most monitors are pretty crud, most LCD monitors use tn screen panels, which are notorious for having poor colour accuracy and tight colour ranges. Better quality panels cost more money, and use either s-ips or s-pva or mva. Most are ips/pva these days.

I run a Samsung 245T 24" widescreen LCD monitor which has a better panel in it and thus, wider colour gamut and better colour accuracy. You can literally > ten thousand dollars on some specialist monitors too. They are super accurate, but you pay through the roof for it.

A cracker image Emanuele, well done.

Nice image Emanuelle ... but then I'm not really surprised as it was taken with a RCOS 24" scope ... did you rent it from Robert Gendler or Russell Croman ... I notice it's located in New Mexico ;)

:thumbsup:

[Emanuele]

Thank you so much to all of you guys :)

Bluescope: no, wish i could rent from them. This was acquired using the scope from Lightbuckets!
It's another world processing images like this one! Very different from the usual.

Dpastern: yes, I am using a 2 calibrated monitors (iMac 24" is the primary). When I save in PSCS3 I convert to sRGB 2.1 profile all my images. The problem I am having, I think, is with iWeb. For some reason, it compresses the images. So if I upload a 1Mb image, and save it from a web browser to see it's properties, I see that it is only 300Kb. I'm not sure what it going on there.

Very nice details. The high-res is superb. 24" RCOS? Lucky you! :thumbsup:

[bojan]

Facebook does the same thing.. I uploaded 20MB image once and ended up with 250kB, reduced both in size and compression.
They are taking care of storage space, that is all.. and on places like Facebook (and iWeb it seems) not many people actually care..

[Emanuele]

Thank you Marc!

Bojan: yes, I think I will move away from iWeb. I just need to find another program that plays well with MobileMe space.

[Tom Davis]

Nice and sharp!

[Emanuele]

Thanks Tom! :)

Gorgeous image Emanuele, lovely and sharp.

[Hagar]

Spectacular detail Emanuele. Your equipment seems to be matched very nicely.

[Emanuele]

Thank you Andrew and Doug!

Doug: I wish it was my equipment but I cannot afford $100,000 of instruments, just yet! This was taken remotely, the observatory is located in New Mexico.

I have updated the image and processed a new version of it, with different colors.

[multiweb]

Wow! :eyepop: Now this is really really cool! :bowdown:

[troypiggo]

Hoooooolyyyyyyy crap. That's awesome! Such detail! Well done mate.

[Screwdriverone]

Oooh, I like the Hubble Palette colour one, spectacular.

Cheers

[Emanuele]

Marc, Troy and Chris, thank you :)

[jase]

Well done Emanuele for today's APOD (http://antwrp.gsfc.nasa.gov/apod/ap090710.html).:thumbsup:
The Lightbuckets 24" RC delivers the goods - impressive data and great processing to boot. Well done.

[Paddy]

Ditto, congratulations!

[Craig_L]

Ditto again.

[h0ughy]

congratulations on a wonderful image, it is fantastic and well deserved of praise

[rat156]

Well done Emanuelle, a deserving APOD.

[Emanuele]

Thank you all! :) I really appreciate your comments guys!

amazing for just 2 frames, makes me wonder why i bother trying to get 8+ hours on any object.
