moon halo was created by spudnik

wow. Saw an amazing moon halo tonight (my first). Spotted it when I went out with the scope about 9pm and as far as I know it is still there.

I live pretty close to an airport and the planes just happened to be flying directly thorugh the halo, drawing pronounced straight lines with their icy contrails. These were then drifting and degrading one by one over time across the halo. Spectacular stuff!

I just wish the damn camera worked...............

Yes

John McConnell and myself saw a partial moon halo on Wednesday 24th November.

Here's one I took in February...



The explanation is as follows...

It occurs when high thin clouds containing millions of tiny ice crystals cover much of the sky. Each ice crystal acts like a miniature lens. Because most of the crystals have a similar elongated hexagonal shape, light entering one crystal face and exiting through the opposing face refracts 22 degrees, which corresponds to the radius of the Moon Halo. A similar Sun Halo may be visible during the day.

Clear Skies

Saw it as well last night at midnight, beautiful ,,took a few shots on B&W film ASA 400 Fuji Neopan.It's my first time photographing one and hadn't a clue re exposure so I used a 28mm f3.5 bracketed from 1/8to 1/30th of a second any info or advice would be appreciated.
Saw a lovely halo a few years ago with Saturn and Jupiter just touching the halo on opposite sides of the moon.

For the image I took...

I photographed a correctly exposed moon at 28mm, ISO100, f2.8 and 1/500second shutter speed. For the Moon Halo, I lengthened the exposure to 10 seconds.

Thanks Markdj,
I forgot to say that my cameras are manual NIkon FG 20s and unfortunately you cant see the exposure needle in the dark I went out now and tried to read the meter and 1/8thsec was as near as I could get on the full moon,next one I'll use your 100 asa metering and adapt iti to my film speed/exposure,
Thanks again
