This is a good method assuming one is tracking and aiming somewhat at one spot. This file can easily be layered on top of the image you use for the background. It now has no background and all your meteors. If an image includes multiple images, be sure to select all the meteors before inverting and deleting the background.Īfter you have finished with all the meteor images, open them into a single file with each image in its own layer. Save the file with a new name that lets you know it is a meteor only. Next invert the selection and choose Edit->Cut to delete everything except the meteor. I tend to set feathering for the selection to 1 or 2 pixels to get smoother selections. In an app like Photoshop, open the aligned image files that contain meteors and zoom in on the meteor and select it with one of the selection tools. Basically each image will be aligned with the rest of the images and written to a new image file. The easiest way I have found is to use an app like DeepSkyStacker and set it to save all the individually aligned images. Is it something that has to be done manually (photoshop)? I've read their manual, searched online, and simply cannot find anything. My question is, when I stack multiple images, some containing meteors, the meteors are not appearing in the final output.
