Title: 22 & 9 Degree Moon Halo Post by: martinastro on December 15, 2008, 06:10:41 pm 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.

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.

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. Title: Re: 22 & 9 Degree Moon Halo Post by: martinastro on December 15, 2008, 09:03:32 pm 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! :)
Does anyone know how to remove lens flares from images using photoelements? Title: Re: 22 & 9 Degree Moon Halo Post by: rjgjr on December 15, 2008, 09:37:01 pm 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.

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.
