The Leonid meteor shower

The Leonid meteor shower happens around November each year when the Earth passes through debris from the comet Temple-Tuttle. The image at right covers a similar area of sky, at a similar angle of rotation to the image I took (below).

The image at right is taken at a much higher exposure and has picked up many more stars and possibly fainter meteors if it was at a higher ISO. Of course the meteors are only there for a fraction of a second.

My image below was a short exposure because the camera was unguided. The camera has a noise reduction function so this shot was exposed for 15 seconds, then the shutter was closed and the noise generated by the sensing chip was recorded for 15 seconds and automatically subtracted from the image. I don't think image stacking software was readily available back then in 2012.
