Want to take better pictures of the moon? There are a few simple adjustments you should make in order to achieve the best results.
First off, always make sure to pack a tripod for this type of shoot. When it comes to low light photography (which any night sky shot is inevitably going to be), a tripod is probably the most important tool to use. Especially since your subject in this case is quite a distance away, you really need your camera to be sturdy. The slightest shake of your hand will drastically damage the quality of this image. A tripod is always going to be your safest bet.
Second, make sure you are using the most effective shutter speed. It's important to keep in mind that the moon is in motion- you're technically shooting a moving subject, so a slow shutter speed simply won't get the job done. Opt for something quicker, like 1/125th of a second instead.
If you have a telephoto lens at your disposal, definitely use that for this shot as well. This is the best tool you can use in order to really capture all the detail on the moon's surface. Without a powerful lens like this, you likely won't get those smaller details you're looking for.
Finally, make sure you remove all filters from your camera's lens before you get started. With such a long distance, highly-focused shot such as this one, you want to take all steps to prevent any type of distortion. The best way to do this is by removing every filter from your lens, even the UV.
