Red Dots
Jul 12, 2018 11:00:27 #
This photo of the full moon was taken with SONY DSC-HX80 camera. I think the I used the Manual mode and zoomed in on it. Was wondered what caused the "red dots" in the photo. I was in the country so no light pollution.

Looks like lens flare to me, but maybe some other more experienced photographers my have other ideas. Good luck

You might do better if you asked this in the Astro Photography forum section. https://www.uglyhedgehog.com/s-109-1.html

I'm voting for lens flare.

It's happened to me when shoot in night lighted pics.ore or less lens flare. Supposed to be from shooting directly into the light. Next time I shoot 1 I'll ll try shooting off center a little. Ended up removing the glare spots in post.

The fact the photo is out of focus probably added to them but only reason I might question lens flare is they are exactly at the top, bottom & both sides from the moon and each exact distance from the moon center when I would have expected them mainly towards the bottom. Could you have caught UFOs flying back to the dark side of the moon? <grin>

Lens flare and extreme overexposure. You have to treat the moon like a daylight shot, since it is lit be reflected Earthlight. See Loony 11 Rule:
The “looney 11 rule” states that for astronomical photos of the Moon’s surface, set aperture to f/11 and shutter speed to the (reciprocal of the) ISO setting.
With ISO 100, set the aperture to f/11 and the shutter speed to 1/100 or 1/125 second.
With ISO 200, aperture at f/11, set shutter speed to 1/200 or 1/250.
With ISO 400, aperture at f/11, set shutter speed to 1/400 or 1/500.

These dots are four alien warships projecting a 4 D hologram of the moon, just to fool everyone. Your camera must have really good red sensitivity.

That would be my guess. There is a lot of glass inside a lens, with a lot of opportunity for light to bounce around and produce unexpected results. Trying to reproduce that exact effect would be a challenge.

Yes, lens flare, and as others said, severely overexposed. While you took this at night, the moon is lit by direct sunlight. So you need to have an exposure setting accordingly. Your lens flare will then be proportionately reduced, making it invisible.

I'm just guessing, but since the red dots are circular it is probably the result of internal reflection between the lens elements.

Do you have a "protection" filter on the lens? Sometimes in extreme light conditions those cause flare like that, too.
