Using the included software, you can separate the video into hundreds of individual images (frames) and digitally stack them to significantly reduce the electric “noise”...

Focusing Tips To achieve best focus, concentrate on a high contrast feature of the object you are imaging. Focusing on small features such as a moon’s shadow on Jupiter or Cassini’s division in the rings of Saturn will guarantee best focus across the entire image. Once the frames of your video are stacked, the overall brightness of the composite (stacked) image is usually brighter than its individual component frames.

Since the NexImage will combine as many sharp frames as possible to achieve one high-quality image, you don’t want to take so many images that you start to detect the rotation of the planet, especially on Jupiter which makes one complete rotation in under 10 hours! Individual frames of a high-resolution video can have large file sizes.
