Sun reflection off something on moon. "Is it man made"

Hi I was looking at some photo's of the moon I took and saw what looked like the sun glinting off something and it looked different from every other feature in the photo. It happens to be in the area of the Apollo 11 landing and I was wondering if it were possible to get a photo of the sun reflecting off the landing stage? I am not sure how to show the photo as it is 1.5 Mb and I am new to photo editing and dont know how to compress it without hiding the reflection if that is what it is any advise as to how to show the picture would be appreciated do I need a website to give a link or can I link to my computer and when I am online would it be available.

I managed to zoom in and cut out the place of interest so have linked the photo.

Thanks

Warren

When you mahe a post scroll down a little and there is a click box that says
Manage Attachments. Click this and click browse to find tour photo, then attach.(it loads the pic to ISS so you don't need an external upload)
It would be interesting to see the pic

At face value, this looks like a hot pixel? Looking around in the attached file, I can see what I think are other hot (as well as cold) pixels where the tone of the individual pixel doesn’t really match the tones that surround it?

If it is a hot pixel, it appears to be in a darker/noisier area of the attached image so it looks quite prominent.

Of course, this is pure speculation on my part based on what I have seen in my own images.

Cheers

Dennis

Yeah I didn't really think it would be Apollo but I was hoping it might be it that would have been great

Hi Warren,
It seems to me like a hot pixel, very tiny i must add!
I doubt the resolution is good enough to catch anything glinting off a bright object on the ground.....but stranger things have happened!
Well spotted though!!!!

Hi Warren,
I know that the smallest object visible on the moon might be a 1km wide crater (with my C11), so unfortunately I don’t think something a few meters wide would be visible from Earth. But good lateral thinking!

An impact would show up as a short lived bright spot too, but any feature would be extremely unlikely to show up as a 1px object unless your focus and seeing were excellent.

A single pixel artefact could also be a gamma ray hit.

I think you're spot on Dennis. If you look at the image as a whole the focus is very soft and there are no crisply defined features at all -- except for that one bright sharp spot.

Well spotted all the same.


Best,

Les D
