The Imaging Source DMK 33UX178.AS, 1/1.8 " CMOS STARVIS, Sony IMX178LL (progressive scan).

The Imaging SourceDMK 33UX178.AS

Monochrome USB 3.0 astronomy camera without IR cut filter.

  • 1/1.8 " CMOS STARVIS, Sony IMX178LL (progressive scan).
  • Resolution 3072 x 2048 pixels (6.3 MP).
  • Up to 60 FPS and 60 seconds exposure.
  • C mount.
  • Software included.

The camera ships with IC Capture.AS, a comprehensive software package with which you can capture lossless and uncompressed images sequences and write them to disk as AVI files, or as a series of singular bitmaps.

Sony IMX178LL 1/1.8 " CMOS STARVIS Chip

The DMK 33UX178.AS ships with the monochrome Sony IMX178LL progressive scan CMOS STARVIS chip. With its 1/1.8 " format, the CMOS STARVIS chip produces a resolution of 3072 x 2048 pixels. Thanks to this extremely high quality, the Sony IMX178LL CMOS STARVIS chip is also often used in other scientific, industrial and medical image processing applications.

No Compression, No IR Cut Filter

The DMK 33UX178.AS does not compress the video stream it outputs - the video data that is captured by the CMOS STARVIS chip is outputted directly by the USB 3.0 connector. Similarly, the camera does not have an IR cut filter, a color filter, nor an other kind of electronic filter. The camera is, therefore, ideally suited to capturing very true-to-life images of the night sky.

High Speed Data Transfer Via USB 3.0

In order to transfer the vast amount of data created by the stream of uncompressed and lossless monochrome images to the host PC, you need a very high speed bus. Hence, the DMK 33UX178.AS is fitted with a fast USB 3.0 connector.

Included Software

The DMK 33UX178.AS ships with the device driver and the camera control and image acquisition application IC Capture.AS. Both of these run on Windows 10, Windows 7, Windows Vista and Windows XP (32 and 64 bit).

Software for Mac OS and Linux is available from third parties.
