Up to 60 frames per second
The astronomy camera DMK 21AU618.AS outputs up to 60 monochrome images per second. It is therefore ideally suited to methods in astrophotography that require high frame rates. It is ideally suited to black and white astrophotography, in which very fast image sequences are captured. Using the shipped software - IC Capture.AS - you can capture lossless and uncompressed images sequences as AVI files.
Monochrome Sony CCD
The camera DMK 21AU618.AS uses the near infrared, extremely sensitive CCD ICX618ALA from Sony. With its 1/4" format, the CCD produces a resolution of 640 x 480 pixels. Even at long exposure times, its noise is minimal. Thanks to its unsurpassed quality, the ICX618ALA is often used in industrial image processing applications.
No compression, no filter
The CCD camera DMK 21AU618.AS does not use compression, nor does it have an IR cut filter, a color filter or an electronic filter. Thus, the camera produces very true-to-life captures of the night sky.
Fast data transfer via USB 2.0
The astronomy camera DMK 21AU618.AS generates a high rate of uncompressed, monochrome images. In order to transfer these to the host PC, a very fast bus is required. Hence, the camera is fitted with a USB 2.0 connector.
NB: Some USB controllers built into PCs might not be able to handle the data rate required for 60 FPS. If you have USB3 (USB3 is better even in USB2-mode) you should not experience a problem. The same might be true of some Firewire connections but we don't have enough feedback yet to comment.

I can recommend the DMK21AU618.AS camera highly. Having used first the webcams spc 900s, and the DFK. DBK DMKs and now the new DMK. The extra sensitivity is really a upgrade over the older DMK camera. Enabling higher focal lengths, and or lower gain. Both desirable advantages. Its IR sensitivity is much greater. I would not have been able to achieve some of the recent Jupiter shots ive taken in 2011, were it not for this camera. Being able to shoot at 60 FPS with no artifacts, is also a big advantage. The greater speed of 1/160secs exposure. And the high frame count. Beats poor seeing more effectively, than at 1/30secs exposure 30 fps. Depending on the size of the telescope and the planet in question being captured. Thoroughly recommended

Q1. Can this camera be used for guiding?
Yes - SteveB currently uses this camera as a guide camera, he finds the Sony 618 chip works well. He has it set to 2 second exposures, he first sets this up in ICCapture to see the stars and then closes ICCapture and uses PHD guiding. In here, choose the WDM camera in the drop down menu.
