Main interface

When launching Siril, the main interface opens.

备注

Click anywhere onto the image below to display its functions.

Image area

This area displays the currently loaded image. Click on Red, Green or Blue to switch between the different layers (color images only, a single BW tab is available for mono images).

Right-click on the image to display a contextual menu:

小技巧

When no image is loaded, double-clicking on the image area pops the Open dialog.

Undo

Undoes the most recent operation.

Redo

Redoes the most recently undone operation.

点扩散函数（PSF）

Computes a PSF for the current selection and carries out quick photometry.

PSF for the Sequence

计算当前序列中所有图像的当前选区的 PSF。

Pick a Star

Applies star detection to the current selection. The result is opened in the Dynamic PSF dialog. Note this operation is more lenient than the full image star finder routine as it assumes that you have picked a selection containing a star: it can therefore be used to pick stars that have been missed by the full image star finder function.

Selection

Applies constraints to the selection box.

Crop

Provides an interface to the Crop and Crop & rotate functions.

小技巧

If a CFA image is loaded, the crop will be constrained to a CFA boundary so that the effective CFA pattern is unchanged for future operations. For Bayer CFA patterns this means the crop selection will snap to a multiple of 2x2 and may shift by up to 1 pixel in x and y directions in order to align with the Bayer pattern start. For X-Trans patters the crop selection will snap to a multiple of 6x6 and may shift by up to 5 pixels in each direction.

警告

Rotating a CFA image by arbitrary angles will destroy the CFA pattern: you should progress your workflow to the point where the CFA pattern has been debayered or Bayer drizzled before doing anything that applies rotation or scaling.

ROI

Provides an interface to set or clear the Region of Interest for ROI processing. Note: this menu entry is not available if the ROI mode is set to "Automatic from selection" in the UI preferences tab.

RGB 对齐

Aligns the image RGB channels. This supports a range of registration methods for alignment:

2-pass global star alignment This uses the 2-pass global star alignment routine with COG framing (so the image dimensions are preserved). This algorithm adjusts with 8 degrees of freedom so it can correct for image shift, rotation and skew. This is the recommended algorithm for images containing stars. This algorithm is global and does not require a selection to be made.
KOMBAT alignment This uses the KOMBAT alignment method. It is primarily intended for planetary alignment, but can also work for deep space images. It provides shift registration only, but is fast. This algorithm requires a selection to be made.
One star registration This is an older algorithm that provides shift-only registration based on the movement of a single star. This is very fast but the registration cannot cope with as many degrees of freedom as the 2-pass global star alignment. It may be suitable if you are certain you only need to correct for image shift. This algorithm requires a single star to be selected.
Image pattern alignment This method performs alignment using the image Fourier transforms. It works for deep space and planetary images but provides only shift registration and is quite slow. This algorithm uses a square selection: a selection must be made, and non-square selections will be corrected to be square.

警告

The tool is RGB align. It is not intended for, and will not work for, aligning unaligned LRGB compositions. In order to do this you must either align the layers to be composed before composition, or align using the RGB alignment tool.
