Stacking types: Aligned stars vs. Star trails

In Nebulb there are two types of stacking that generate two different types of images: aligned stars and star trails.

1. Aligned stars: In this case Nebulb, before stacking, performs an alignment of the stars of all the images with the image selected as base, so that the result is an image with all the stars as they were in the base image, but without noise. In a way this type of stacking is like a kind of a software star tracking mount, since Nebulb detects and corrects the displacement of the stars before performing the stacking.

1. Star trails: In this case Nebulb performs a specific stacking to record the trails left by the stars as they move across the sky due to the Earth's rotation.
