The Menu Bar


The File menu item has the following options.


SharpCap Settings

The SharpCap Settings defaults have been chosen to enable ease of use of the application with minimal configuration required after installation, however adjustment to the settings can be made here when necessary.


See Configuring SharpCap for a detailed description of the four tabs General, Hardware, Filenames, and Startup Scripts.


Selecting Exit or Alt+F4 will perform an orderly shutdown of SharpCap.


The Cameras menu item allows selection and de-selection of attached imaging devices.  These may be cameras or video capture devices (frame grabbers).


Two ‘built-in’ cameras are provided:

1.       Test Camera 1 (Deep Sky), a simulation of a capture of the M42 Nebula in the Constellation of Orion.

2.       Test Camera 2 (High Speed), a simulation of a capture of Jupiter (the dark spot to the lower left being the shadow of a moon).

These two test cameras can be used to learn the functionality of SharpCap without requiring a telescope and camera.

[Note: some cameras (particularly ASCOM and DirectShow cameras) may show in the device list even when they are not connected to the computer – selecting one of these cameras not currently available will give an error message.]

Rescan for Cameras

If a camera connection is lost or a camera plugged in while SharpCap is open, use the Rescan option to find the device.

SharpCap automatically rescans after a USB device is added to or removed from the computer.  The rescan button is mainly useful to detect network connected cameras (i.e. Basler or Point Grey Gig-E cameras) as SharpCap cannot detect these being added to the network.

Available Cameras

Select the camera to use from the dropdown list.

There may be occasion when a camera appears twice in the available cameras list.  If in doubt which one to select, use the one highest in the list (because SharpCap tries to put the cameras it has the best control over at the top of the list).  See the Philips SPC 900NC in the graphic below.


Sometimes it is useful to close the camera currently in use without opening a different camera.  This can be achieved by returning to the Cameras menu and choosing the selected camera from the menu again.


The Options menu item has the following items.


Full Screen

The Full Screen option forces SharpCap to switch to full screen mode.  This leaves only the Capture Display Area and Camera Control Panel visible – there are no menu or tool bars available.  To reverse this situation, move the mouse pointer to the top of the screen and the menu will appear.  The Full Screen option can be unchecked.

Reset Control Order

In the Camera Control Panel, each control group has a handle at the top right corner.  This handle can be grabbed with a mouse and the control moved elsewhere in the Camera Control Panel to suit individual preferences.  By choosing Reset Control Order, the control groups can be returned to their default order.


Other Options

Depending on the manufacturer/model of camera connected and selected in SharpCap, other menu items may appear in the Options menu.

These are the additional menu items available when a Microsoft LifeCam (webcam) is connected and selected.



The Capture menu item has the following options.


 Capture allows control of:

·         The capture process.

·         The production of dark frames.

See Capturing Videos and Images for a detailed description of these menu items.


The Tools menu item provides access to specific functions which can assist in capturing images or ensuring alignment of the telescope.


Live Stack

This option provides the same functionality as the Live Stack button located on the Tool Bar.  See Live Stacking for a full description of the tool.

<ALT> < L> can be used as a hot key combination to initiate Live Stack.

Polar Align

Selecting Polar Align will produce a set of screens to manage the alignment process.  See Polar Alignment for a detailed description.


The Scripting menu item allows access to the Scripting Console and gives the ability to run existing scripts and write new scripts.  The scripts are based on Python.  The functionality of SharpCap can be extended by using scripting as a built-in programming language.

Scripting is an advanced topic and knowledge of it is not essential to be able to use SharpCap effectively.


See Scripting for a full description.


The Help menu item has the following options.


View Help

View Help will display a manual, in Windows help file format, installed as part of the of the SharpCap software.

Check for Updates

Selecting Check for Updates will initiate a version check against the SharpCap website of the installed versus latest version.  If no updates are available, the message below is displayed.


If an update is available, a download and installation is offered.

Report a Bug

This option provides a simple mechanism to report possible bugs or issues directly to the developer.  The capture PC/laptop must have internet connectivity for this to work.


Fill in the text and press the Send button.  It would be useful to provide contact details such as an email address.

SharpCap shows ASCOM focuser positions on the Focus score graphs

If you are using an ASCOM focuser from withing SharpCap and you use one of the focus aids that displays a graph (FWHM or Contrast detection), SharpCap will display a trace of the focuser position overlaid on the focus score graph.

This can be very helpful as you can see which position on the focuser gave the best focus score. Remember that most focusers have some degree of mechanical backlash, so always aim to approach the target score from the same direction.

Show Log

SharpCap, in the background, is constantly logging events relating to the program.


Click the Copy to Clipboard button to copy the contents of the log.  By opening Notepad (or other text editor) the contents of the log can be pasted and a file saved.  The information on how to send the log file can be found at .
