BTW how do you differenciate a hot spot from a sun? =D </DIV>That's a very good question!<br><br>Here's how:  Hubble images are acquired in black and white (luminance measurements only), and color images are created by combining luminance exposures taken through different colored (e.g., red, green, blue) filters.  The "stuck" hot pixels that persist from frame to frame are already removed from the images by the Hubble "calibration" software, so...  If I find a bright green pixel and no evidence of it in the blue or red channel, it's very likely not a real object.  Real objects usually have SOME presence in two or all three channels.  Also, good as it is, the Hubble does not focus even the very sharpest stars onto one pixel; they're usually spread across at least 2 or 3.<br><br>My understanding is that many of the intermittent hot pixels are the result of cosmic rays impacting the imager.  We have all this wonderful atmosphere protecting us down here on the Earth's surface from most of that.<br><br>-Noel]]></description>

They collect mountains of data and then either don't do anything with it or make a slapdash analysis that's 'good enough'. Often, years later someone will re-examine data that was overlooked or not processed and find something extraordinary. I believe some of the outer dwarf planets like Sedna were photographed, but never discovered because the images were never given a thorough examination. I hope your partnership can help do justice to some of these magnificent pictures that were acquired with such great effort and expense.<br><br>The hunger for more and more data seems to cross all disciplines and is growing at a very fast rate. When the LHC goes online soon, the data volume will be in terabytes <I>per day</I>. Who's going to to be able to look at that flood of data? I've read that they'll need to network thousands of computers across the web just to get a rough idea of what they're creating. <br><br>Maybe this push for more information and the processing power needed to examine it in a reasonable time will benefit us all in the long run. Who knows? There may be semi-sentient programs developed soon that can see patterns and order in what we mere humans only saw as noise. <br><br>Congratulations on your many achievements and letting us all see a little clearer.<br><SMALL>--<br>Sic transit gloria mundi<br></SMALL>]]></description>

<description><![CDATA[<A HREF="/useremail/u/468775"><b>wapu</b></A> : Your NGC 6441 Image is amazing! It has a WOW factor that is off the charts. Incredible really. You are gonna force me to buy monitor software that will let me have multiple background images. ;-)<br><br>On the NGC 5866 image, I opened <A HREF="http://ncarboni2.home.att.net/NGC5866_Hubble_Noel.jpg">yours</A> and <A HREF="http://www.spacetelescope.org/images/large/opo0624a.jpg">theirs</A> in my browser at full size and did a side by side compare moving around the image and focusing on background galaxies and stars that looked interesting.<br><br>I also downloaded their TIFF and opened all three in Photoshop and did a similar side by side comparison. I would center all three images at the same object and look at them.<br><br>I am no expert but since you took the time to process these and ask for comments, I figured the least I could do is look closely at them and tell you what my untrained eye sees. Forgive my lingo.<br><br><B>My assessment:</B> <br>In your image the actual galaxy looks sharper and the coloring is less blue. I see that as an improvement. <br><br>I can understand their cropping out the left upper star. Having both it and the bright upper right star create a symmetry to the whole image that distracts me from the galaxy itself. I see that as a personal preference and not better or worse in either.<br><br>Where your image really distinguishes itself is in the transition of the "glow" from the bright of the center galaxy to the darker outer galaxies and stars. Yours is smooth and natural looking. Theirs is grainier and some of the sharpness of those objects in that glow is lost. You have made a definite improvement.<br><br>Focusing in on the bright star in the upper right corner, your image shows detail in the center of that star. Theirs is a big white circle. Even the more distant stars and galaxies surrounding that star are sharper than theirs. This is true all over the image.<br><br>My untrained eye says you have made an improvement to their image. I do not want to take anything away from theirs. I am sure I would have been truly amazed at it had I not had your superior image to compare it to.<br><br>Really great work and thank you for sharing these with us. I hope my comments made sense.<br><SMALL>--<br>When a friend asks me to choose between friends, I will always choose the friend that didn't ask me to choose.</SMALL>]]></description>

<description><![CDATA[<A HREF="/useremail/u/868867"><b>NoelC</b></A> : Hi folks,<br><br>I have been asked to demonstrate my astroimage processing skills to the ESO folks who process Hubble Space Telescope data into images. Specifically, they've asked me to find an object that's already been photographed and is in the Hubble raw data database, but that's never been made into a full color image before (scientists take images for scientific study without ever making them into pictures as we know them). If they like what they see I'm hoping they'll offer me the opportunity to join their team.<br><br>I found one: Globular Cluster NGC 6441<br><br>It's a distant globular in Scorpius, and it's scientifically interesting in that it seems to contain one of the very few planetary nebulae found in a glob (faintly visible just to the right of the core), as well as an xray source / pulsar / possible black hole. These interesting things have been studied using the Hubble, but no one's ever attempted to create a full-color visible spectrum image from the various Hubble exposures before now. I assembled this mosaic from several dozen Hubble exposures taken through a variety of wide and narrow-band filters and using several different cameras.<br><br>This image begins to show off the amazing resolution of the Hubble Space Telescope.  Keep in mind this image covers an area of the sky less than a quarter the size of the moon.  And you should know that there are some Hubble exposures, for example of the central core, that are of a significantly higher resolution than shown here, as taken by the Advanced Camera for Surveys. However, I used the overall lower resolution of the Wide Field Planetary Camera II with which the entire cluster has been imaged.  <br><br>Most Earth-based images show this cluster as just a blob.  Here's a Google image search revealing existing NGC 6441 images online:  <A HREF="http://www.google.com/images?q=ngc+6441&nojs=1">Click here</A>.<br><br>Without further ado, I give you NGC 6441 like you've never seen it before.  I guarantee it!<br><br><A HREF="http://ncarboni2.home.att.net/NGC6441_Hubble_Processed_by_Noel_Carboni.jpg"><IMG SRC="http://ncarboni2.home.att.net/NGC6441_Hubble_Processed_by_Noel_Carboni_Small.jpg"></A><br><br>Time spent processing:  5 hours.<br><br>--<br><br>As I wanted to continue practicing and learning about Hubble data, I chose to process another Hubble acquisition, this time a galaxy:  NGC 5866, sometimes also known as Messier 102.<br><br>It turns out the Hubble Heritage Project has recently shot some long exposures through wideband red, green, and blue filters with the express intent of releasing a nice image to the public.   They took 3 single images with the Advanced Camera for Surveys (ACS).  Red:Green:Blue exposure times were 65:47:37 minutes over a period of 4 HST orbits.  You can see their version at these sites:<br><br>&raquo;<A HREF="http://www.spacetelescope.org/images/html/opo0624a.html" >www.spacetelescope.org/images/ht&middot;&middot;&middot;24a.html</A><br>&raquo;<A HREF="http://hubblesite.org/newscenter/newsdesk/archive/releases/2006/24/image/a" >hubblesite.org/newscenter/newsde&middot;&middot;&middot;/image/a</A><br><br>Theirs is a truly spectacular image, but I wanted to see whether I could improve any on the image processing they did, as I spotted a fair number of defects in the full-sized image, albeit minor ones.  I'd love to know whether you think I did manage any visual improvement.  Note that I didn't crop as much off the left and bottom as they did.  <br><br>I loved seeing all the distant background galaxies. <br><br><A HREF="http://ncarboni2.home.att.net/NGC5866_Hubble_Noel.jpg"><IMG SRC="http://ncarboni2.home.att.net/NGC5866_Hubble_Noel_Small.jpg"></A><br><br>After opening the 600+ megabytes of FITS files from the Hubble database, stretching (brightening) the linear data, and normalizing the color channels, things I did to this image were:<br><br>&#8226; Cropping to a rectangular field of view<br>&#8226; Hot pixel removal (mostly with the healing brush)<br>&#8226; Alignment of the color channels within 1/4 pixel<br>&#8226; Noise reduction<br>&#8226; Sharpening<br>&#8226; Darkening of the diffraction flares around the stars<br>&#8226; Removal of several "doughnut" artifacts from the brightest two stars at the top, assumedly from the refractive optics added to the HST to fix the initial mirror problem<br>&#8226; Noise reduction in several bands across the image that appear to be the result of imperfect silicon fabrication.<br>&#8226; Contrast enhancement<br>&#8226; Increase of color saturation<br><br>Time spent processing:  5 hours.<br><br>-Noel]]></description>
