A very high quality 22 degree Moon halo was visible late last night when cirrostratus cloud arrived before a warm front. The halo was extremely bright and even had a 9 degree halo on the inside around the Moon which is something I have only seen once before, during the day. Anybody else see it? Some good Geminid meteor activity around too, I was hoping I would capture one within the halo but I wasn't that lucky.

Lovely Martin. Haven't seen the sky without clouds since Thursday of last week. No Geminids, no close approach moon...

Yes Martin, I saw the 9 degree halo as well though I have not checked all the images I took to see if I captured it. Here's one I got at about 0315UT, by 0430 thicker cloud had arrived. You can see Gemini to the right of the moon, Procyon below.

Guys, I looked out at about 0400 and saw exactly the same as your photos, though I wasn't aware of the 9 deg halo. In fact, I'm pretty sure I've never seen a 9 deg halo, only the more familiar 23 deg variety.

I took circa 100 images earlier in the night but didn't catch a single Geminid!

Clear skies,

Paul.

Nice one John!. You have that 9 degree halo (and 22 degree halo) very well captured. We were observing that halo at the exact same time!  Smiley

Does anyone know how to remove lens flares from images using photoelements?

Martin, depending on the size and severity of the lens flare, I have used the cloning tool or paint brush to some success. You just have to enlarge it alot and be persistent with it.

Here's a slightly better one showing that 9 degree halo, if you move back about two feet from the PC screen you will see it better. It actually pass's between Castor and Pollux.

Thanks for the tip Richard. I will keep that in mind for the future! Cheers.

John, the 9 d halo shows up very well there. There's great depth to your images. What did you have the aperture at?. Mine was F/4, was yours F/5 or something?

The larger and brigther Moon must have been the reason why that halo was so big and bright.
