Title: Lunar halo (07 Feb)
Post by: brianb on February 07, 2009, 11:20:26 pm
No sooner does the showery cloud dissipate & the wind drop than the frontal cloud moves in, bringing a really notable halo with it.

Nice image Brian!. That's a great wide angle lens you have.

Seen the halo also and it was a beauty. Very bright, complete, and with vivid colours. One of the best 22 degree Moon halos I've seen for a while, or at least this year anyway. frontal system is over W Ireland at min.

Witnessed the brightest lunar halo I have ever seen! I swear I could see the colors easy by naked eye!

Nice one Tyler! I take it that formed on the leading edge of the system which could produce the storms?.

Yes, the halo last night was one of the best I have seen in a long time.

Nice shots guy's, here's one of my images from last night. The halo was one of the best I have seen in a long time, thanks for the heads-up Martin otherwise I might have missed it. I don't usually see much colour on these moon haloes, but last night it was very noticable especially at the bottom. Gemini can be seen inside the halo. This image is untouched except for resizing.

It cleared for a while after this and then while talking to Martin on the phone I looked outside and saw this most beautiful corona caused by the thinest of clouds which I could still see the stars of Gemini through. I rushed to try and capture it before it was gone. The colours were something else. Image untouched except for resizing.

Hey John, very nice images. I can see the bright enhancement at the bottom of the halo. The shot of the corona turned out great with Castor and Pollux complimenting the scene.  :)

Oh.. marvellous !  I've got to get out there. I don't have any astro. gear  that's why I haven't tried but I see yours -Brian- was taken with the 5D and a 16mm  aperture (16-35mm  f2.8 ?). I've only used the 100-400mm  for the moon. I wouldn't have thought a W/A would have got anywhere near but it obviously has. I can get that 16mm with my 10-22mm on my 1.6 X crop camera so I'll have a go next time.

Great set of captures gents. I've not seen a halo yet, in fact I've barely seen the sky in nearly 2 weeks now....

Thanks Tyler, it was a beauty, but as with most corona's like this it didn't last long, only a few minutes and the thin cloud that caused it melted into the background sky once it had moved away from the moon.
