Esta ferramenta deixa-o preparar um mosaico para a sua câmara.

Há duas maneiras para abrir esta ferramenta:

  • From the menu View, in this case the mosaic is centered on the screen center, corresponding with the last object search.
  • From the right click popup menu, in this case the mosaic is centered on the mouse cursor position.

  • You can adjust the coordinates of the mosaic center, or use the arrow button to move the mosaic. Press the Ctrl key for larger move or the Shift key for smaller.
  • The camera rotation can be adjusted to change the global mosaic orientation.
  • Give a name to the mosaic, this is use as the default file name and prefix every row in the file.
  • Select the Finder rectangle that correspond to your camera. It is better if your imaging software can plate-solve and send the frame to Skychart. This way you get the exact size and orientation automatically.
  • Change the size of the mosaic as you want.
  • Set the vertical and horizontal overlap in percent.

When ready click the Save button to record the mosaic definition to a file you can later load in your imaging software.

You can also send the mosaic via the server connection.

Below is a description of the format if you want to write your own software to process this mosaic.
