Not only is the Moon illuminated from way too south, which would never happen, it is also about 6 times bigger than the Pleiades in the lower left corner. Angular diameter of the Moon is less than that of the Pleiades. It is also way too far from the ecliptic.

Just something that itched my eyes.

The perspective is also all wrong, or the fence is 100 m tall.  I think it's ok to use double exposures to show both the Moon's surface and stars, but care must be taken to get scales roughly believable.

Guys, i'm learning photoshop. This is composite of 2 images. I photographed the moon through telescope and just blended it in but a little bigger and gave him inaccurate shadow because it looked cool.

Shouldn't that picture be on the Show off your work topic then?

Is that real time?  I've never seen one before so I have no idea how quick they move.

Yes, that is real time, semi-fisheye lens (about 150 degrees diagonally).

here one of the my first ,(presentable) astrophoto of M27
taken with:
newton 750/150
canon EOS 550D
25mm ocular
10 poses 60 seconds
elaborated with iris and photoshop
it's a crop of the original because my instrument have a bad spherical aberration, so the  stars at the edges appears elongated.

Looks like someone jumped to warp-speed!

Fun fact:

The "Popping in of HD textures" bug in Space Engine has happened a lot of times in many versions (for Intel users is very common).

Image

While reading this, I just remembered that the first time I saw the Aristarchus Plateau in SE (when I was totally ignorant about anything related to Selenography) I just thought that it was a huge patch of HD texture added badly to the surface of the Moon. There was not the slight attempt from my computer or the author of the lunar texture to blend this region naturally with the rest.

Then one day I looked through a telescope and instantly realized it is really like that in the real world! Many of you are probably aware of this but for me it was mind bending. A feature in the Moon that looks totally unrealistic and computer rendered. Here you have some amateur and LRO pictures of what I mean.

Look at the upper left corner of the region in the last image. Is such an abrupt change in geology and is all bounded by such a seemingly artificial rectangular shape that it fooled me completly at that time.

I don't have a photo, but wanted to mention that Venus is very bright and close to the Moon now.  I was able to spot it with unaided eyes at noon, with the Sun 19° above the horizon.  It is surprising how visible it is in broad daylight, provided you know where to look and have something like the Moon nearby to help guide you. :)

Wow, I did not know you can see Venus at noon!  Is it less than half a degree from the Moon (about the angular diameter of a full moon)?  I had heard some people ask if it's possible to see the brightest stars if you're deep down in a well but I don't think that's possible.

Yes.  Cloudy here, but I got a report from one of the meteor cams this morning, false detection, but it shows the situation nicely.  Venus is magnitude -4.5.
