| 説明 | This is my attempt at astrophotography with Sagittarius, the milky way, globular clusters and Jupiter. After many difficult adventures and frustrating attempts I found that this is actually easy, go figure. This was taken with a Canon SX100 IS on a $9 walmart tripod. Camera settings in manual mode: ISO1600, F2.8, Shutter speed 15 seconds, Manual Focus to infinity (or as far out as you can get it), and Self-Timer 2-seconds (to get rid of shakes when shooting begins). Post processing was done with DeepSkyStacker (awesome free program) . Stacked 21 Lights, 10 Bias, 10 Darks. After stacking the pictures it looked like I messed things up (very bright image/washed out, the saved image on desktop looked okay) but I took the image to Adobe Creative Suite 2 (not free, but you'd be amazed at who around you may have a copy, so ask around). In CS2 I changed the contrast slider button, the brightness, thought wow, lets move the red and blue slider button too, lol and saved it. I found that DeepSkyStacker did VERY well and that the image was not messed up, I'm not sure why. Please Please ask questions or make comments. I want astrophotography to be enjoyed by all and it almost destroyed me, till again I found out how easy it is. Thanks to my twin brother who helped encourage me through this, and Skype for letting us exchange photos. |
