Hi
I am using my DMK21AU04 USB camera on a Coronado PST, and the live preview screen keeps freezing, so I can't focus properly. It seems to record avi's ok. I have only had the camera a few days, and was wondering if anybody had some idea what the problem is (properly me)?

Thanks in advance

Bob,

the AVI capture has a higher priority than the live display. Thus you can not see the live video due to AVI capture. If the used codec is fast or you use a fast computer, then the live video will be displayed too. I have the same issue on my AMD 1600+ when I use the old MJPEG Compressor.

Hi Stefan

Thanks for the quick reply. I was trying to focus with live view, and then record an avi. Perhaps I was recording in the background without realiasing. I will check again tomorrow, weather permitting.

Hi
Had another go today focusing on plants at bottom of garden (overcast and wet here today), and everything worked just as it should do. I am using codec Y800.
I didn't use a IR filter that I have yesterday, won't screw in 1.25" adapter and I don't want to risk cross threads. I can make up a temparory adapter, using the lower half of an eyepiece so I can screw in the IR filter, just have to wait for weather to clear.
Has anybody else had problems using un-filtered H-alpha with a Coronado PST or similar type of scopes.
