Canon DSLR Off By One Images - Very Dangerous! - by: kbahey

I am facing a problem with a Canon DSLR 650D with KStars/INDI. Using the latest stable version 1.7~201803061317~ubuntu16.04.1.

What happens is that I tell it to take a 120 second image. But what happens is that it takes an 18 second image only, and then from that point forward, all the images will be delayed by one. So if you do a slew then a plate solve, it will be on the previous image. The result is that the scope now things it it pointing somewhere that is not right, and it may crash in the mount.

I used to see this problem in the past (last summer), and could simulate it at will, but only by doing a manual step, as per the following:
- Connect the camera to USB
- Start INDI
- Take an image.
- After the image is taken, go to the camera and take an image manually.
- From this point on, INDI will be off by one.
- When trying to turn off the camera it will display a blue image saying 'saving image' or something like that, and will hang there until you pull the power or battery out.

Now, this happens without me touching the camera at all ...

One thing I noticed is that the count down timer for the exposure now contains decimals. Previous it was always xx.00, now it is xx.99 or some other value in the fraction part.

Is this a bug? Or is there a setting to prevent this?
