Do you need a tracking mount to photograph meteors?
Is a tracking mount necessary for meteor shower astrophotography? We explore the advantages.
The Perseid meteor shower peaks on the night of 12/13 August and under dark skies is an ideal target for astrophotography. In 2020 the Moon may cause some interference as it lies in the morning sky, but you can still capture meteors with a camera on a fixed tripod.
That’s the usual wisdom, but it is also worth thinking about using your camera in conjunction with a portable tracking mount.
This is not often suggested as meteors appear as fast blips of light in the night sky, so you might be asking "why would you want to track the stars?"
There are several reasons why the many portable tracking mounts for DSLR astrophotography can be useful when capturing meteor showers as, and I'm sure many will testify, most images will be devoid of meteors.

Meteors are not that predictable, even during a shower, so why not take lots of tracked exposures of the night sky and do two jobs for the price of one?
Yes, I know, I used to work at a major retailer and buy-one-get-one-free was often the mantra!
Such mounts are highly portable too so you could go to a darker or better site with perhaps a larger expanse of sky uncluttered by houses and the such like.
This way, those images that, say show the Milky Way, can be stacked at a later time to bring out more detail such as star clouds, dust lanes and nebulae.
So even if you don't capture many meteors, you'll still have something to show for the night’s effort.
Tracking mounts are also useful for keeping the radiant in the same position on the image for a nice composition, so you get to use the whole image on all your exposures.
Plus, if some of your images do have meteors on, then you can overlay them on your stacked, richly-detailed Milky Way image and end up with a super duper image to show off to your friends and astro colleagues, not to mention send up to our astrophotography gallery.

However you decide to view or image this year's meteor shower, good luck and clear skies!
