Lunar halo - 19 Aug 2005

[Dennis]

Hello

Last night I set up my new C9.25 to try some Lunar imaging with my LPI and was lucky enough to capture this Lunar halo with a consumer digital camera.

Explanation from Dr Charles Wood of LPOD fame at http://www.lpod.org/archive/2004/06/LPOD-2004-06-03.htm

"The ring is made of Moon light that is refracted (bent) as it passes through an ice crystal. Moon rings only occur if there are relatively high (and thus cold with ice crystals) wispy clouds. The common hexagonal shaped crystals bend the light by 22 degrees (two fist widths, if you want to measure it), so the entire ring is 44 degrees wide".

Cheers

Dennis

well done Dennis, nice capture

the last time I saw a lunar ring I took a handful of pictures with a film Canon which was all I hasd at the time...you can imagine what Big W did with the film in processing :(

Very science fiction looking Dennis. Almost like you're looking along the hull of a space ship heading toward some sort of hypergate. Excellent shot
