Sequator

In case you are into star photography, then chances are that you are looking for a little helper to aid with post-processing your images, especially since not everyone can afford an equatorial mount or highly expensive gear in general. Sequator is a tiny and user-friendly tool that compensates for the lack of exotic gear and that provides a quick way to stack non-blur star images in short-time exposures.

The program comes with a simple interface that is easy to navigate regardless of your experience with similar tools. While on the left side you can add the base, noise and clear images, in the right panel you can preview your work in real time.

To get the best results, you should get some non-blur, well-focused pictures with proper exposure parameters where various stars should be obvious. At the same time, the developer recommends you take a few noise images with the same ISO and exposure time. The reason for this is that the app may recognize some noises as stars and the stacking becomes null.

If you have both noise and non-noise pictures, you can easily process your images and reduce light pollution, enhance star light, add gradient, so on and so forth. As a side note, if you are having any sorts of problems with the application, do not hesitate to check out the manual, as it provides useful information.

While most of us would like to capture the beauty of the night sky, in most cases what we get when pointing the camera at the sky is a disappointing exposure that comes out completely black. Sequator is a tool that can help you make the most of these shots and, as the developer points out, tries to suppress the learning curve for anyone getting started with star photography.

The tool is not a replacement for the existing astrophotography apps out there and it may even be limited compared to them. The idea behind it is that it addresses beginners and amateurs who are still practicing with finding the right technique as it can save time and energy.
