But that was because the planet was already covered by the Moon. Then at 6:08 am local time
at the beginning of twilight the first sparkle of Venus emerged from the
dark limb of the Moon and in a few seconds brightened to its usual
glory. The sight of a diamond glint held just beyond the horns of the
crescent Moon was enchanting! Pentax Kx 300mm telephoto.<br />

This full moon was the closet to Earth full moon of any other this year. This not only makes the full moon look about 7% larger than average but also puts it deeper into the Earth's shadow during the eclipse darkening it a bit more than usual. It was further darkened due to volcanic ash from the Calbuco volcano in Chile still erupting since earlier this year. The dust and smoke injected into the stratosphere served to filter out more of the refracted sunlight bending around the earth's circumference to the surface of the moon.<br />
<br />
The following sequence of images were taken at the last few minutes before the beginning of totality. Camera is compact <a href="https://www.canon.com.au/en/Personal/Products/Cameras-and-Accessories/Digital-Cameras/Powershot-SX-150-IS">Canon Powershot SX150</a> pushed to full optical plus digital 48x zoom!

While these encounters occur every year they are not all so well placed in the evening sky like this one, Close encounters with the Pleiades occur every 8 years. the last was 3 April 2004, the next 3 April 2020. <br />

She is joined by Mercury just to the upper left and Mars, the brighter of the two near the top edge of the picture. Venus and Mercury are gaining height each night and will join Mars next week. <a href="http://i144.photobucket.com/albums/r177/marty_0750/Photo-full/vemema-080825.jpg">Larger image</a><br /><br /><span style="font-size:85%;"><span class="postbody">Pentax K100D; 30 sec; ISO 800; Sigma zoom 40mm; 25 August 2008 9:29UT </span></span>Martin Lewickihttp://www.blogger.com/profile/15229035482483417784noreply@blogger.com0tag:blogger.com,1999:blog-7599096769650007463.post-72605572139861851792008-03-08T17:34:00.006+10:302008-03-08T18:20:44.778+10:30Aurora Australis<img src="http://lh4.google.com/martin.lewicki/R9I14K5RQ6I/AAAAAAAABCk/fx75ieXjqJs/s400/IMG_0152_med.jpg" /><br /><br />Aurora Australis from Mt Nelson, Tasmania on 10 February 2008. It unexpectedly appeared during group sky viewing session. The aurora shimmered and changed by the minute. The green was easily visible to the eye while the red showed up in only in this image that I took with a <span style="font-style: italic;">Canon PowerShot A550,</span> 15 sec, ISO 800.<br /><br />Aurora occur when the Sun produces a coronal mass ejection (CME). This cloud of charged particles travel out from the Sun at about 400 km/sec. When a CME brushes past the Earth, the Earth's magnetic field acts a shield to protect us but some of the particles manage to channel down through the north and south magnetic poles to collide with atoms of the Earth's upper atmosphere, about 80km up (the image shows clouds in silhouetted in the foreground). This excites atoms that produce light. The green and red come from atomic oxygen molecules.<br /><br />I've see aurora twice before from Adelaide. They were fleeting lasting only few minutes. But this time I was ready with a camera and the Mount Nelson aurora obliged us with a show that lasted more than an hour!<br /><br /><a href="http://en.wikipedia.org/wiki/Aurora_%28astronomy%29">More about aurora from Wikipedia</a>Martin Lewickihttp://www.blogger.com/profile/15229035482483417784noreply@blogger.com3tag:blogger.com,1999:blog-7599096769650007463.post-10214831503671581792007-10-26T22:35:00.000+09:302008-12-11T06:12:12.167+10:30October Big MoonThis month's full Moon is closest of the year.

Planetary photography like you see here is made easier with digital cameras and electronics. You just keep adjusting the exposure settings until you get good shots. The telescope has remote control to reduce shaking from handling and the camera has delay exposure to allow <span class="blsp-spelling-error" id="SPELLING_ERROR_11">vibrations</span> to subside before exposure. This kind of planetary photography with a small telescope and compact camera would have been almost impossible with film and manual telescope controls. </p><br /><br /><br /><br /><p align="left"></p>Martin Lewickihttp://www.blogger.com/profile/15229035482483417784noreply@blogger.com0tag:blogger.com,1999:blog-7599096769650007463.post-76368461915866052042007-07-18T22:09:00.000+09:302007-10-23T21:40:20.032+09:30July PlanetsWas hoping to get the close grouping of 17th July but cloud got in the way.
