Hello Robin,
I tested yesterday the first time the image dithering during the Live Stack with the 4.2.15217 beta.
It was working with short exposure time (5 to 10 seconds). But it was no more fine with 30 or 60 seconds exposure.
I used "Dither only (no guiding) using ASCOM mount pulse guide".
What I remarked ?
With 60 s exposure and the camera in Force Still image ON.
Start the Live Stack during an exposure of 60s. The image arrived and added in the stack.
The next images were a sequence with one 60 s image added in the stack, one 60 s image not added and several short 2 s exposure during the dithering. The 60 s image was not added and the status mentioned it as "waiting during dithering".
It is annoying to lost the half of the 60 s exposure when SharpCap seems to wait during some dithering.
I tested different settings of the "dithering" parameters, but without success.
Can you give me some parameters values that should work ?
Regards,
Jean-Francois

Re: Missing images during Live Stack with dithering
Hi Jean-Francois,
sorry to hear about the lost data. Unfortunately I think this is likely to be the sort of problem that needs digging into to understand why it is happening. My first guess is that code that is supposed to spot a frame where the capture time of the frame overlaps with the time when the dithering was happening is being triggered incorrectly. If that was the case then you would likely find entries in the SharpCap main log along the lines of
If you have those lines, knowing the reason would help pin down what might be happening.
thanks,
Robin

Re: Missing images during Live Stack with dithering
Hello Robin,
I have the telescope outside with my EAGLE computer ... so the log file is not easy to retrieve when the weather does not allow to open the telescope cover. But I can try to reproduce the problem with other camera and my desktop computer.
Concerning the dithering .. for my test, it was set after each frame.

Jean-Francois
