Oldfield So, over in Hong Kong, has published an interesting article about debayering techniques for the DBK and DFK series of astronomy cameras.
He discusses the following three techniques:
Case A: Debayer’ing is done at hardware level, and so the data coming from the camera is already in full color. [...]
Case B: By choosing Y800 for the device codec, the hardware sends original data which is not yet debayer’ed, that saves some Firewire bandwidth, and then the debayer’ing is done at software level by IC capture. [...]
Case C: We have chosen Y800 for the device as above, so the data coming from the camera is still not yet debayer’ed, and therefore, it uses less Firewire bandwidth. And Debayer’ing is also disabled in IC Capture, meaning that Debayer’ing is not done on-the-fly as well, and so it requires less CPU cycle.
He has published a screenshot for each technique, one of which that illustrates the third technique, is below:
You can read the full article, in Oldfield’s blog.
A great thanks goes out to Oldfield for sharing this information with The Imaging Source astronomy cameras community.

The blog of astronomy society in Saint-Michel Mont Mercure, France - more commonly know as Saint Michel Village du Ciel - has recently published an interesting blog about IC Capture.AS and The Imaging Source astronomy cameras. The article contains a great image of Saturn and a couple of deep sky images. Click through to see them (link below)!
In addition, the author has published the following screenshots of IC Capture.AS in action:

The capture program for Linux is called ucview, which deploys the unicap library.
I am delighted to announce that unicap 0.2.22 has just been released.
It now ships with the following improvements:
- Better support for The Imaging Source USB 2.0 astronomy and industrial cameras
(download the uvcvideo driver)
- Added and fixed some color conversion routines
- GTK+ apps can register their own color format conversion callback
- Some minor fixes in the unicapGTK library
- Support for recent uvcvideo drivers
- French translation (thanks to Kiki Novak!)
- Packages for Ubuntu Hardy
You can download the source code package from the unicap web site:
http://www.unicap-imaging.org/download.htm
Packages for Ubuntu 7.04 (Feisty), Ubuntu 7.10 (Gutsy) and Ubuntu 8.04 (Hardy) are in the repositories:

We have talked about using The Imaging Source astronomy cameras on Linux previously (here, here and here).
The capture program for Linux is called ucview, which deploys the unicap library.
I am delighted to announce to better support the Linux astronomy cameras community, a set of unicap forums have been launched:
If you have any matter related to running The Imaging Source astronomy cameras on Linux with ucview and unicap, please do not hesitate to post your questions into the above forum.
The forum is maintained by the program’s chief developer, Arne Caspari.
