Andromeda galaxy "angular diameter is 178x63 arc-minutes.". And the moon is roughly 30 arc-minutes. So this looks twice as thick as the moon and six times as wide.

If a telephoto lens was used and it was close to the horizon, the sizes could work.

But I am also sceptical. Camera sensors have come a long way, but they can't capture that much light without a long exposure. And a long exposure would require tracking the stars, so the mountain would get motion blur.
