right. When dragged to the left, the side panel can also be closed.
o Statistcs: Displays image statistics including Minimum, Maximum,
Average, and Median values.
o Histogram: Displays image histogram with controls to adjust the
minimum and maximum values for each channel. Both linear and
logarithmic scalings are available to apply to the image.
o FITS Header: Displays a table for FITS header keywords, values, and
comments.
o Recent Images: Displays recently opened images. Clicking on any image
will load it.
4. Image Display Area. Hovering over the image will update the status bar values
accordingly.
5. Status Bar: From right to left, the following status indicators are available:
o Loading Indicator: The LED becomes yellow when an image is getting
loaded and turns green after loading is successfully done. If there are
problems with loading the image, it turns red.
o Resolution: Image resolution in pixels.
o Cartesian Coordinates: Displays and updates the current mouse position
as you hover over the image. It include the X and Y position in addition
to the current value.
o Equatorial Coordinates: If the image contains a valid WCS header, the
J2000 Right Ascension (RA) and declination (DE) values are displayed.
In addition to image display, the viewer can process World-Coordinate-System
(WCS) header if present within the FITS file and provides useful information
regarding the objects found within the image, equatorial grid overlay, popup
menu, and the ability to slew the mount (if connected) to any point within the
image.
Several filters can be applied to enhance the image include auto stretch and high
contrast. Depending on the image size, these operations can take a few seconds
to complete. The bottom status bar displays the current pixel value and current X
& Y coordinates of the mouse pointer within the image. Furthermore, it includes
the current zoom level and the image resolution.
When loading a bayered image, the viewer can automatically debayer the image
if Auto Debayer is checked in the FITS Settings. The debayering operation fetches
the bayer pattern (e.g. RGGB) from the FITS header. If none exists, you can alter
the debayering algorithm and pattern from the File menu or by using
the Ctrl+D shortcut.
Since operations such as auto debayering and auto WCS are computationally
expensive and stress the processor on low-powered embedded devices, you can
