Coordinates grid

Icon: grid

Menu: Overlay => Grid

Short key: Alt+G

Activating a grid can be done either with the “grid” icon located below the view, or using

the menu “Overlay => Grid”. The grid step depends on the current zoom factor in order

to only display a reasonable number of sectors. The grid frame is the same as the one

used to display the current location with the mouse. It is not possible to display

simultaneously different grids corresponding to different referentials.

If the zoom factor is very small (1/512x), the grid can seem truncated if the astrometrical

solution of the current image is inaccurate to compute a location far off the image (e.g.

digitized Schmidt plate).

Target arrow

Menu: Overlay => Target Arrow

Short key: Alt+T

When an image was queried either by location or by object name (see 5.2

– server selector), a small red arrow gives the location in the image. This

arrow can be deleted using the menu item “Overlay => Target Arrow”.

Multi-view

In order to compare more easily several images, it can be useful to create several view

simultaneously. The main panel can then be divided in 2, 4, 9 or 16 sub-panels. Each of

these panels can display a different image and superposed graphical additions. These

images can sample different regions of the sky or the same one. It is also possible to use

different panels for a single image, for example in order to visualise different details in

this image.

Number of views

Icon: multiview

Menu: Edit => Multiview …

Short key: F1, Shift+F2, F2, F3,

Modifying the number of visible views

can be done either with the “multiview”

selector located at the bottom left of

the view panel, or with the menu “Edit

=> 1, 2, 4,9, or 16 panels”. If the views

that are used are more numerous than

the number of available panels, then a

sliding bar appears on the right of the

main window and enables you to

access the other views. Up to several
