Work on a sequence of converted images
Once you have your Siril's format .fit files, you can switch to the sequence tab seen below. Sequences are what Siril uses to manipulate files.
Click on the "search sequences" button. If you only have one .fit files sequence in the working directory, it is automatically selected. Else, the list will pop-up an you'll be able to select the sequence you want to use. When the sequence is loaded, two windows are opened: the grey frame control window, on the left of the image below, and the RGB composition rendering window, behind the main window on the image below.
The grey window is used to display colour components for the image, control their composition in the colour image, and give information about the displayed frame, like the layer's name (for now it can be only Red Green or Blue, but it will be settable to narrow bands some day), pixel value when moving the mouse on a pixel, file name and layer number, FWHM calculation is an area is selected (result is quite experimental), and zoom value.
The cursors at the bottom control thresholds for black and white on the grey image, allowing to play with contrast and lightness of each channel, mainly for previewing purposes.
