Cool right?</p><p>Maxim DL Capture software screenshot - I have been asked before if I ever see strange stuff while imaging and the answer is yes and here is the perfect example. The software takes one picture after another in succession and while imaging M-10, on image 9 this is what I saw on the laptop screen. Remember that this is one 30 second image and that line to the right of the cluster is a satellite that happened to be flying by. The next day while processing these images I found the beginning of the fly by in image 8 and the end of it in image 10.</p> <p>The stacking process works that noise (technical term, honest), in this case a satellite trail out of the final image because that faint trail is not in the other 16 images in that spot.</p><p>M-5 Globular Cluster in the constellation Serpens.<br /> Magnitude: 5.8<br /> Distance: 24,500 light years.<br /> Dreyer description: Very remarkable!, globular cluster, very bright, large, extremely compressed middle, stars of magnitude 11 to 15; = M5.<br /> 15 images stacked.</p> http://lebowsky.newsvine.com/_news/2012/05/18/11750207-view-the-annular-solar-eclipse-sunday-on-the-cheaphttp://lebowsky.newsvine.com/_news/2012/05/18/11750207-view-the-annular-solar-eclipse-sunday-on-the-cheapscienceastronomyastrophotographyannular-solar-eclipseview-the-eclipsepinhole-projectorFri, 18 May 2012 04:36:50 +0000http://activitystrea.ms/schema/1.0/posthttp://activitystrea.ms/schema/1.0/generic_post<p>Finished Pinhole Projector</p><p>White paper added for viewing screen.</p><p>Aluminum foil with pinhole taped in place.</p><p>Pinhole in aluminum foil made with a sewing needle.

The window should be about twice as long as it is wide because you will be looking at the inside end of the box at an angle.</p><p>Boxes are ready to join together and I used a hot glue gun. Glue was applied to the 4 tabs on the left box and then slid inside the box on the right. Reaching in through the viewing window it was easy to just press them in place. The tabs on the right box where then glued down one at a time to the box on the left and this made for a very sturdy joint.</p><p>Materials used in this projector and ready to go, 2 long boxes, aluminum foil and white paper.

The green border at the bottom of the images is the horizon. The red horizontal line is 2 degrees Altitude (0=Horizon) and the red vertical line is the Azimuth (Compass Heading) of 297 degrees. The times in EDT for the 3 images are 8:24PM, 8:30PM and 8:36PM with the Sun setting (Sun moves below the horizon) at 8:44PM.</p><p>This is a 6 image simulation of the partial eclipse for 5-20-2012 as viewed from Fort Worth, Texas. This series starts with the Moon's initial contact at 7:33PM CDT with the Sun's Azimuth at 288.2 degrees (compass heading) and Altitude at 9.2 degrees (above horizon - 0 degrees). The images then progress at 9 minute intervals until the Sun and Moon are at the Horizon shown as the green bottom border at 8:18PM. The Sun's Azimuth at this point is 294 degrees and the Altitude is 0.3 degrees. The Sunset is complete at 8:24PM.</p><p>You bet it does and the proof is in the pudding as they say. With the projector in my left hand pointed over my head at the Sun and my point and shoot in my right hand I took this image this morning. The insert is a full size image from the original and images are as is out of the camera, no touch ups. Watching the eclipse you will clearly be able to see the Moon's dark silhouette covering the Sun. Remember that today is also the day of the New Moon and its phase is virtually 0%, not illuminated.</p><p>Quite a few things as a matter of fact, The Pleiades aka The Seven Sisters will be a witness to the whole thing along with Mercury and Jupiter. All of this is taking place in the constellation Taurus, The Bull, and there is even a small portion of the Milky Way in this chart image from 9:30AM today May 20, 2012. The blue circles represent areas of nebulosity (gas clouds) and the stars are only shown out to about 15 magnitude. This is a busy place. From the time of this chart the Moon will cover the 4.1 degrees separation to the Sun and cross over it with the end of the eclipse around 10:20 EDT, almost 13 hours.</p> http://edmgeno.newsvine.com/_news/2012/05/13/11686779-a-new-angle-on-titanhttp://edmgeno.newsvine.com/_news/2012/05/13/11686779-a-new-angle-on-titanspacesciencesaturnastronomytitancassiniastrophotographySun, 13 May 2012 19:20:04 +0000http://activitystrea.ms/schema/1.0/posthttp://activitystrea.ms/schema/1.0/bookmark http://minnieapolis.newsvine.com/_news/2012/05/06/11565346-supermoon-around-the-worldhttp://minnieapolis.newsvine.com/_news/2012/05/06/11565346-supermoon-around-the-worldphotosartspicturesphotographastrophotographysupermoonSun, 6 May 2012 16:57:31 +0000http://activitystrea.ms/schema/1.0/posthttp://activitystrea.ms/schema/1.0/generic_post<p>Images of Supermoon from around the world, in a slideshow from HuffPo. </p> http://lebowsky.newsvine.com/_news/2012/05/06/11563713-moon-ya-later-gator-updated-5-06-2012http://lebowsky.newsvine.com/_news/2012/05/06/11563713-moon-ya-later-gator-updated-5-06-2012moonastronomyartsastrophotographysuper-moonmay-5-2012Sun, 6 May 2012 16:00:41 +0000http://activitystrea.ms/schema/1.0/posthttp://activitystrea.ms/schema/1.0/generic_post<p>This is the almost Full Moon setting on May 5, 2012 at 5:43AM EDT.</p><p>No the moon did not have a baby :o)<br /> This is the moon setting on Saturday morning May 5th and it is about to hit a street light.</p><p>The moon rise on May 4 and 5 side by side to show what a difference a day makes, time and position in particular.

It sure was pretty.</p><p>April 24, 2006 I was trying out new Capture/Processing software and was not to sure what I had imaged out there in the dark looking at the raw images. During the processing the next day, I was in for a big surprise. I had captured a piece of the comet breaking off.<br /> This image and inserts shows a bit of the effort and the learning "how to" that was required to clean up those initial images. The main culprit was light pollution from a far from perfect site.</p><p>April 27, 2006 The fragment has fallen behind and is not visible in this image. This is a stack of 21 x 20 second exposures with the scope tracking the comet through the star field.</p><p>From the night of April 24, 2006. The second time imaging a comet and I catch part of it breaking off.</p><p>Bonus Image April 28, 2006</p> <p>Yes I was out imaging the comet on the 28th but while I was digging around in there looking for the comet images I came across this beauty and didn't think you would mind a break. </p> <p>The comet was doing it's thing and in the neighborhood was this magnificent beauty. Messier object number 13 or M13 is a Globular Cluster. This is where stars are born and this is the largest nursery around. </p> <p>M13 is just visible by eye in a dark sky in the constellation Hercules.</p> <p>This image is a stack of 55 x 20 second exposures for a total of 1,100 seconds (18.3 minutes) of exposure time or 3 cigarettes.</p> http://lebowsky.newsvine.com/_news/2012/04/18/11267187-astronomy-coming-up-and-looking-backhttp://lebowsky.newsvine.com/_news/2012/04/18/11267187-astronomy-coming-up-and-looking-backscienceastronomymeteor-showercometlyravegaastrophotographylyridscomet-73p-c-schwassmann-wachmann-3lyrid-meteor-showerThu, 19 Apr 2012 02:05:14 +0000http://activitystrea.ms/schema/1.0/posthttp://activitystrea.ms/schema/1.0/generic_post<p>In this image the telescope is tracking the comet speeding through the star field. I took a total of 40 images of 30 seconds each, one right after the other automatically via the capturing software Maxim DL Essentials. Out of those 40 images, 10 were thrown out for not meeting the quality cutoff resulting in the final image being made up of 30 images stacked, representing a total of 15 minutes of exposure time. Why it is done this way is because each image adds resolution to the final image. If just one 15 minute exposure was taken, the image of the comet would be way overexposed.</p> <p>Now this imaging session was 20 minutes long with the 40 images originally taken so notice how far through the star field the comet flew in that time. Also of interest is that the stars appear as streaks and the missing portions in those streaks represent where the bad images were in the series, kind of like missing teeth. Had the telescope been tracking the stars, the comet would have appeared as the streak through this image.</p> <p>The reason for 15 minutes of exposure time on the comet is to resolve the key components which are the Coma, Nucleus and the Tail. More exposure time would have been better to a point. Part of the learning process.</p> <p>Just for the record, 1 astronomical unit is equal to the mean distance of the Earth from the Sun.</p><p>This is basically the same image as above without the presentation information and with a slightly different final processing applied.</p><p>This purpose of this presentation image was to demonstrate that if you plan to image in light polluted skies part of the learning process is learning to deal with it.</p> <p>Also of interest here is that the exposure time of each image in this stack is only 15 seconds as opposed to the 30 second exposure time in the images above. Again part of the learning process and there are advantages to both times of exposure. Can you see the differences?</p><p>This chart shows the constellation Lyra and neighbors looking East at about 2:00AM EDT on Sunday the 22nd.</p> http://edmgeno.newsvine.com/_news/2012/04/17/11248303-special-new-panorama-celebrates-hubbles-22nd-anniversaryhttp://edmgeno.newsvine.com/_news/2012/04/17/11248303-special-new-panorama-celebrates-hubbles-22nd-anniversaryspacescienceastronomyhubble-space-telescopenebulatarantula-nebulaastrophotographylarge-magellanic-cloud30-doradusTue, 17 Apr 2012 16:22:23 +0000http://activitystrea.ms/schema/1.0/posthttp://activitystrea.ms/schema/1.0/bookmark http://edmgeno.newsvine.com/_news/2012/04/16/11232404-top-10-really-cool-infrared-images-from-spitzerhttp://edmgeno.newsvine.com/_news/2012/04/16/11232404-top-10-really-cool-infrared-images-from-spitzerspacesciencegalaxyastronomyspitzer-space-telescopenebulaastrophotographyiracinfrared-array-cameraMon, 16 Apr 2012 22:33:01 +0000http://activitystrea.ms/schema/1.0/posthttp://activitystrea.ms/schema/1.0/bookmark http://edmgeno.newsvine.com/_news/2012/04/14/11199128-see-big-and-bright-saturn-at-opposition-this-weekendhttp://edmgeno.newsvine.com/_news/2012/04/14/11199128-see-big-and-bright-saturn-at-opposition-this-weekendspacesciencesaturnastronomyastrophotographyastrphotographySat, 14 Apr 2012 15:37:53 +0000http://activitystrea.ms/schema/1.0/posthttp://activitystrea.ms/schema/1.0/bookmark http://edmgeno.newsvine.com/_news/2012/04/06/11059186-astrophotos-from-around-the-world-of-the-venus-pleiades-conjunctionhttp://edmgeno.newsvine.com/_news/2012/04/06/11059186-astrophotos-from-around-the-world-of-the-venus-pleiades-conjunctionspacescienceastronomyvenusastonomytaurusastrophotographypleiadesseven-sistersconjunctionFri, 6 Apr 2012 19:18:01 +0000http://activitystrea.ms/schema/1.0/posthttp://activitystrea.ms/schema/1.0/bookmark http://edmgeno.newsvine.com/_news/2012/04/04/11018317-the-ufo-galaxy-object-found-by-the-nasahubble-space-telescopehttp://edmgeno.newsvine.com/_news/2012/04/04/11018317-the-ufo-galaxy-object-found-by-the-nasahubble-space-telescopespacesciencegalaxyastronomyhubble-space-telescopeastrophotographyngc-2638Wed, 4 Apr 2012 15:57:51 +0000http://activitystrea.ms/schema/1.0/posthttp://activitystrea.ms/schema/1.0/bookmark http://edmgeno.newsvine.com/_news/2012/04/04/11017664-watch-live-webcast-of-venus-pleiades-conjunction-april-4-2012http://edmgeno.newsvine.com/_news/2012/04/04/11017664-watch-live-webcast-of-venus-pleiades-conjunction-april-4-2012spacescienceastronomyvenusastonomytaurusastrophotographypleiadesseven-sistersslooh-space-cameraWed, 4 Apr 2012 15:06:15 +0000http://activitystrea.ms/schema/1.0/posthttp://activitystrea.ms/schema/1.0/bookmark http://lebowsky.newsvine.com/_news/2012/03/27/10886443-hello-moon-o-the-finale-march-26-2012http://lebowsky.newsvine.com/_news/2012/03/27/10886443-hello-moon-o-the-finale-march-26-2012sciencemoonastronomyjupitervenusastrophotographym36m-36Tue, 27 Mar 2012 20:30:49 +0000http://activitystrea.ms/schema/1.0/posthttp://activitystrea.ms/schema/1.0/generic_post<p>March 26, 2012 - Composite of the Moon with inserts of Venus and Jupiter.
