This night I got the sprites at a perfect distance and the clear skies I was hoping for!
At the moment I did not yet use UFOCaptureHD because the DirectShow driver of the camera does not allow me to use a slow shutter speed, while at medium/fast shutter it skips frames (and seems to capture 20 fps). I opened a support ticket at Point Grey to see if it can be improved.

Slow shutter seems not a problem at all to use, it captures many stars, the camera has low noise even at maximum gain, and I could clearly capture some normal variety meteors also recorded by the Watec (1/2", 8mm F1.2). I used a 25mm F0.95, 23 dB gain, gamma 2.0, shutter 6-8 fps.

I will soon post images to my website, below is a good one for you. It only has a slight local contrast applied to counter the glow effect of the lens at F0.95-F1.4.

happy regards,
Oscar

Wow

impressive Razz

It may be the most precise one I ve ever seen.
more over, it is beautifuly in the center of the frame.

I am now updating UFOCaptureHD2 for 4K capturiing.
To avoid the frame drop, multi threading part is increased.
Now It becomes almost OK for 4K 24p, by i7 4790 3.6GHz 4c8t.
Tonight, I will test 30p by i7 4790K 4.0GHz 4c8t.
If it goes well, I will release UFOCaptureHD2 V4.0 in several days.

I hope the sprite season still continues....
