Beautiful composition! But I wonder about this:

Is that really Saturn? I think I can see the Pleiades at far right, and I think - think, mind you - that I can spot the Great Square of Pegasus to the lower left of the bright planet. But if so, then the planet in this position is Jupiter, not Saturn.

Jupiter is of course a lot brighter than Saturn in our skies, and would stand out more.

It is indeed the Pleiades which can be seen on the right side of the image at the height of the tower. Capella is visible as the bright star just right of the tower. Higher up we see stars belonging to Perseus´left foot, and just above the tower most of the W of Cassiopeia can be seen in an upright position. Even higher are stars belonging to Andromeda; the Andromeda Galaxy can be seen as a faint smudge. Above this lies the square of Pegasus. So the planet can be no other than Jupiter.

First off the shower radiant is separated by a good 100+ degrees in azimuth from the moon and is also higher in the sky. What appears to be the Pleiades shouldn’t be there it should be way over to the left of the castle out of the image. Going by the Moon and Saturn there is only one star cluster there and that is a globular one m30 and the cluster on the image is obviously an open cluster.
Maybe I am missing something obvious or I just don’t know what I am doing with the programs but something is missing.
Can any body post an illustration putting this image in relation to a wider sky shot because I am stumped! :(

This image was made from hours of data. The only way you can do that when there's a full Moon is to cut out the individual meteors from each image that captured one before you stack them, and then composite those with one or more images capturing the Moon, the tower, maybe some stars. And depending on how you isolate the meteors, you may leave stars in those exposures, as well (for instance, if you cut out the area around the Moon instead of tightly cutting out the meteor). So it makes perfect sense that there is no clear star pattern to be seen, just a few individual recognizable asterisms, the positions of which can't be compared because they were captured at different times. The bright object to the right of the Moon is quite properly placed to be Saturn (Jupiter was clear over on the other side of the Moon at the time), and it makes sense it was captured in the same exposure that captured the Moon.

Fantastic work Chris, thanks for sharing!
I’m curious about what kind of scope and imager you used? Did you use a light intensifier? I also like how you put the compass marks on the image.
Great image!
