About this product

Model:  DMK_21AU04.AS_mono

Monochrome USB 2.0 Astronomy Camera with 60 fps for Astrophotography - without IR cut filter.

  • 1/4" CCD, progressive scan
  • Resolution 640 x 480
  • Max. 60 fps
  • Max exposure time 60 min
  • C/CS Mount
  • Software included

Up to 60 frames per second

With 60 fps, the monochrome astronomy camera DMK 21AU04.AS is the fastest within its category. 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 astro CCD camera DMK 21AU04.AS uses the monochrome progressive scan CCD ICX098BL 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 ICX098BL is often used in industrial image processing applications.

No compression, no filter

The CCD camera DMK 21AU04.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 21AU04.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.

After several years using a Philips webcam I decided it was time to move to the next level. I did hum and har for some time because these cameras are not cheap. On the face of it they seem little more than a glorified webcam.
I opted for the mono version for the higher sensitivity, I also chose USB2 over fire-wire.
The camera feels very solid and oozes quality. The USB cable could do with being a little longer though it does suffice. Although the cameras top speed of 60fps is widely quoted you will read in specialist forums that it is not advisable to use it (image quality issues).
The biggest bugbear however is the ease of which dust bunnies find their way onto the CCD (or the glass that protects it). The first time I used the camera there must have been 5 of the little blighters. They are not easy to remove either! Cotton swabs, pure ethanol (hard to get hold of) and a lot of patience are the order of the day.
That said it does produce an excellent image. The added sensitivity combined with 30fps (when the target is bright enough) come together to produce excellent results. Now the financial hit has faded into overdraft history Im glad I own this cracking bit of tech.

Used it a long time, and got a lot of good results with it. It is simple to use, and supported by various 3rd party software (+ the default IC Capture). DMK21 for planets, and 31/41 for Moon/Sun. They don't have ROI so you can't make DMK41 faster when catching small planet with it. They also can handle DS imaging a bit - in the planetary style catching a lot of frames on few-sec exposures (if you can limit the gain by 1/3-1/4 and increase the exposure time to make the target bright enough).

Using 60 FPS shutter will usually create circular artifacts on stacked planet image (the same for 31 and 41 models and their max. shutter speeds). The upcoming after summer version should have this fixed (and the super sensitive ICX618 CCD).
