Drivers QSI Cameras

Native Drivers; ASI Cameras: This driver MUST be installed for Windows users to use ASI cameras.: v3.16. Change Log: Released. EFW: These products are USB HID devices so do not need native drive. Cooled CMOS Camera QHY600M/C. 16bit 61mpixel BSI FF. 16-bit A/D 26Mpixels BSI. 14bit 11mpixel 4/3inch BSI. 14bit 24mpixel BSI FF.

I just downloaded the new QSI ASCOM drivers (v1.0.0.4) as well as SGP v3.1.0.295 and installed both. If you are using QSI cameras you will need to update both the camera selection to “QSI Camera 2” AND the filter wheel selection to' QSI Filter Wheel 2' in your “Equipment Profiles” (ALL of them) and in the Control Panel for ALL your sequences. I completely overlooked the Filter Wheel.

Moravian Instruments CMOS Cameras

SharpCap supports Basler cameras for high speed capture and also provides a unique LX mode with certain models that allows exposures beyond the normal limits of the camera.

All Altair Astro cameras are supported in SharpCap.

All ZWO cameras are supported in SharpCap.

All QHY CMOS Cameras are supported by SharpCap. QHY CCD cameras are known to work in SharpCap 3.1. Older QHY CMOS cameras may require the use of an ASCOM driver.

Imaging Source DFK and DMK cameras are supported by SharpCap. Imaging Source cameras are now sold under the Celestron Brand as Skyris and NexImage cameras – these are also supported by SharpCap

SharpCap supports FlyCapture based Point Grey Cameras. USB, GigE and Firewire cameras are supported. SharpCap does not yet support Spinnaker cameras.

SharpCap supports iNova cameras.

SharpCap supports the SV305 directly and the SV105 and SV205 via their webcam drivers.

SharpCap (from version 3.2) supports Atik cameras without needing to use an ASCOM driver.

SharpCap (from version 3.2) supports Moravian Instruments CMOS cameras without needing to use an ASCOM driver. CCD models may also work.

There are a vast number of webcams and frame grabbers on the market. In general, SharpCap should work with any of them, but some cameras/grabbers have buggy drivers which may prevent them from working correctly with SharpCap. In any case, the controls that are available in SharpCap are determined by the driver – SharpCap just shows the controls that the driver makes available. Sometimes more controls are available in the ‘Video Capture Pin’ and ‘Video Capture Filter’ dialogs which are also provided by the device driver.

SharpCap (up to version 3.0) still supports LX modified webcams that are controlled either by serial or parallel interfaces.

How is SharpCap Different for Webcams?

Most basic capture applications, such as AmCap and similar programs require the camera to be restarted completely when moving between preview and capture mode. This can be a problem for modern webcams as the restart may through away camera settings that you have just adjusted by re-initializing the camera back to an ‘auto’ state. SharpCap can move between preview and capture mode without needing to stop and restart the camera, which sidesteps this problem completely, as well as allowing captures to start more quickly.

Additionally, SharpCap allows the images being captured from a webcam to be processed by all of it’s sophisticated features available to dedicated Astro cam users – for instance Live Stacking and Polar Alignment are both usable with images coming from a webcam or frame grabber providing that a long enough exposure can be set to start seeing details and/or stars.

SharpCap supports cameras that have an ASCOM driver. Unfortunately not all ASCOM drivers are created equal – much like webcam drivers. While SharpCap works correctly with most ASCOM drivers, in some cases the driver may have bugs or may not follow the ASCOM standard in quite the way that SharpCap expects.

Comprehensive Software Support

Every QSI scientific camera is accompanied by a collection of software applications and tools that allow you to begin imaging immediately using Microsoft Windows® or Linux platforms. QSI cameras are supported on the Macintosh by 3rd party applications.

QSI provides robust Application Programming Interfaces (API) for both Windows and Linux environments, enabling commercial customers and end users to write their own custom camera control applications.


The installer includes USB Drivers, User Guides and ASCOM support. You will be able to optionally install native plugins for AstroArt during installation. If you received a complimentary code for SGPro with your camera you can download it here.

Windows Microscopy Applications

Plug-in for Micro-Manager

µManager is software for control of microscopes. It works with almost all microscopes, cameras and peripherals on the market, and provides an easy to use interface that lets you run your microscopy-based experiments. Together with ImageJ, μManager provides a comprehensive, widely supported, open source, freely available image acquistion and processing solution.

μManager has a simple and clean user interface which allows you to execute common microscope image acquisition strategies such as time-lapses, multi-channel imaging, z-stacks, and combinations thereof. μManager works with microscopes from all four major manufacturers (Leica, Nikon, Olympus and Zeiss), a wide range of scientific cameras and many peripherals used in microscope imaging, such as stages, filter wheels, shutters, etc.
Learn more about μManager


Notes:There are separate plug-ins for 32 and 64-bit version of µManager. It is important that you download the correct QSI µManager plug-in for the version of µManager installed on your system. Note that it’s possible to install and run the 32-bit version of µManager on a 64-bit sytem so best to confirm which version you are running. Since µManager is a written as a plug-in for ImageJ, launch µManager, then select Help > About ImageJ… The 64-bit version will show that you’re running the 64-bit version of Java.

The plug-in requires that the latest version of “QSI USB Drivers and Software” is installed, which can be found above.

Custom Application Development

Windows® Custom Application Development

QSI provides both anASCOM-compatible API (Application Programming Interface) alongside a more traditional C API enabling users to write their own custom camera control applications. The camera control API is an automation component that communicates with the camera device driver and exports a COM automation interface. COM automation provides an interface that allows Microsoft Office, VB, VBA, C++, and other Windows applications to control the camera. Our C API allows you to write your application in any language that can interface with the C language.

Linux Custom Application Development

QSI provides a camera control C++ API for Linux users. The API provides full camera control and image capture capabilities via the USB interface. The API is implemented as a shared library providing an easy to use camera object that exposes all of the features and capabilities of the camera. It is well suited for both simple scripting, and more sophisticated imaging application development. The QSI Linux API requires Linux kernel version 2.6 or later configured with libusb. The QSI Linux API is distributed in source code form and can be built using the standard GNU configuration and build tools. See the ChangeLog and README files in the archive for additional details.
