Yes, being able to provide astronomy training to teenage girls is rare in the schools. They will learn to take and process images using Siril, and for the older girls we will teach science aspects like variable stars using the aperture photometry.
In your reply you said "it allows to work with aligned sequences". The process I am documenting does the registration first, then allocating PSF for the sequence. Is the export/import process required to align the images?
This is the process I am using:
The process for registration is as follows:
1. Select the Sequence tab.
2. You can step through each of the images by clicking the + or - buttons. The image will be shown in the second window.
3. You can optionally exclude some images from the sequence (for example images of poor quality due to seeing or passing cloud). To exclude an image click the Excluded checkbox.
4. Select one of the images as the reference image by clicking the Reference image checkbox for that image. Only one image can be the reference image in a sequence, setting it will unset the image previously set as reference. If not set manually, the first image of the sequence is taken as reference.
5. Select the Registration tab.
6. On this tab, do the following:
a. Click Register all images from sequence (unless you have excluded images as per above).
b. In the Choose registration method select Global star alignment if it is not already chosen
c. Click the Translation only checkbox
d. Click the Go register button to start the registration process.
If sufficient stars exist in your images, the Output logs tab will show the data associated with them and indicate that the images have been successfully registered.
Then I planned to go to the selection of the stars (V, 1, 2, 3 etc).
Or do I need to do the export followed by an import of the sequence to get the alignment working correctly?
I appreciate your help, as I want to make sure the girls use Siril appropriately.
