Hi,

running atik_ccd_test just after connecting my Atik Titan gives the same timeout error and the test fails (see test.txt).
At this state ekos can't capture images from the camera, it hangs on downloading the image.
But after taking a long exposure (5 minutes) with Ekos, all works fine. Closing ekos and running
atik_ccd_test again now gives 'Atik Titan test OK' (see test2.txt).

So the procedure to get my Titan working is:

1. Connect the camera to USB
2. start indiserver
3. connect ekos to the camera
4. take a 5 minute exposure

After that I can also take short exposures.
This behaviour occurs on PC with 32 and 64 bit Kubuntu 15.04, 32 Bit Lubuntu 14.10 and rasbian & fedora on bananaPi.

Best regards

Strange, but good to know. Peter

I will try this.

BTW, how long are your short exposures? The hardcoded threshold for using short (camera timed) a long (computer timed) exposure is 0.5s so from software point of view there is no difference between 1s, 1 minute or 5 minute exposure. Peter

Hi,
sorry for my late reply.

Last night I found the reason for the strange behavior of my Titan. It is the temperature. Yesterday I setup my scope on daylight and all works like a charm. After dusk I polar align the mount. Ready to start to get pretty pictures. But the Titan says no. No chance to get a single image from the Titan. I wonder why the Titan works in the afternoon but not in the night. And then I've got it: the temperature changed. So I heaten the camera's body with a hair dryer and the Titan works again.

Under room temperatur condition the 5 minute exposure seems to suffices to warm up the camera electronics. Maybe the frequency change in respond to the crystal oscillator's temperature coefficient is big enough to break the timing of the atik driver. My Titan works normal with windows.

With short exposures I mean everything shorter than a minute or so (0.01 s to 60 s).
