FREE IMAGE STACKING SOFTWARE PROFESSIONAL

You will want to open the resulting images in your favorite graphic program and try to enhance them further with various tools, among which the histogram adjustment and multiple layers are the most useful. The program doesn't display the resulting images, it only saves them as png files.

An image where each pixel goes through a histogram filtering algorithm (maximizes the contrast).

An image where each pixel is averaged from all the original images.

An image where each pixel is the darkest of all the original images.

An image where each pixel is the brightest of all the original images.

Then it merges all the images and it produces several images based on statistical computations: It optionally saves each aligned image in the same directory with Aligned in the name. The program determines the rotation to apply to each image for an optimal alignment. In case of broken sequences, press to use the current and previous image as a base for all the following alignments (just like you did on the first two. The dimension of the cross represents the area on which the brightest point is searched for. Manually selected points are shown with a straight cross while guessed points have a diagonal cross.

If not you can just click on the proper location.

Do again to verify that the guessed points are correct.

The program will now estimate the position of the same points on all the other images.

You don't need to be very precise: the program places the cross on the brightest peak.

Do the same on the 2nd image, selecting the same stars, even if they have moved a little.

Select two bright points (stars) on the first image with respectively the and.

Press to verify that the order is correct (they should be in lexicographic order).

All the images (jpg or png files) should be in the same directory.

Drag and drop the images into the program.

Increased possible image size (although that depends on underlying libraries) Expanded destination image v1.2 - 9 - Added optional dark frame removal, file exclusion, wheel actions and a few user interface improvements. History: v1.0 - 5 - Original release v1.1 - 2 - Minor modifications and bug fixes. With this program you can for instance set your camera on a tripod, take a bunch of 30s exposures of the night sky (more time will lead to star trails) and stack them to enhance the contrast.

The difference between this program and more professional ones are the following: it's free, it works with jpg (and png) format so you can use it with images taken with digital cameras, and finally it's much simpler. This process is used mainly on dark images to remove the noise level. This program is similar to many astronomy programs in that it is meant to take several images and merge them.

Some images available on a royalty-free compilation CD.

'Why is it that if someone tells you that there are 100 billion stars in the galaxy you will believe them, but if they tell you a wall has wet paint you will have to touch it to be sureВ ?'
