Yes, I tested with 60s (countdown reached 0 after 46s). And tested other exposure times as well.

Looking much better now. No "shorts" anymore and pictures taken adhere to the exposure time that was selected. One issue remains though. The countdown is not correct. Every 1s it counts down in ca. 1.2s steps. This means when you take a 60s photo the countdown will reach 0 after ca. 46s and you'll have to wait another 14s before the shutter is actually being closed.

Hi Jasem!

I do the same thing again, add a 5s photo to the sequence and activate it.

What happens now is

2s of waiting
counter starts. at the same time shutter is opened and closed immediately
counter counts like this: 5 3,80 2,55 1,45 0,26 (these values vary)

This happens 100% of the time. All pictures are "shorts" and too dark. A logfile is attached although I'm afraid it won't be helpful.

Pulled git.

What now happens is this: I choose 5s for exposure, add to sequence, start sequence...

1. mirror will go up but no counter is shown
2. after 2s counter appears and starts counting like this: 5 6 5 4 3 2 1
the shutter is opened at "first 5" and closed at "2"

so the exposure time is 5s indeed but I think this is not what was intended.
The wait time of 2s is nowhere shown.

If I choose 1,5s for exposure, add to sequence, start sequence...

1. mirror will go up, no counter
2. after 2s counter shows 1,5s and counts like this: 1,5 2,5 1,5 0,5
Unfortunately the old error appears again. Every other photo's exposure time is too short. Attached is a logfile where I have taken 3 photos at 1,5s each. Photos 1 and 3 are "shorts" (shutter closed immediately after being opened) while No. 2 was OK.

Hi, I am unable to make a connection to my asi294. Three days ago it did connect and I was able to use it just normally. With the latest updates though I get

so basically the cam is connected and recognized by the USB bus. The cam works just fine in Windows. Any ideas what the problem might be?

Alfred replied to the topic 'problems with guiding' in the forum. 3 days ago

Calibration is the next thing we have to sort out. Since the internal guider most of the time didn't work for me, I resorted to guiding via lin_guider "plugin" in ekos which does the job well. Yesterday I got a new ASI 0294 with ST4 guide port so I wanted to quickly connect it to indi, use it as a "luxury guider" and enjoy the huge field of view. It didn't work. Just as it was the case with my QGuider most of the time, the damn thing would not calibrate. It starts moving in RA but once the movement is reverted, the star just stops moving, or even moves in a 90 degree angle to its previous movement (and that happens well before movement in DEC is activated). I'm sure the mount (Alt 5) is not to blame since it works very reliably and doesn't suffer from backlash or similar issues. The symptom is the same for both guiders. I'll provide logs as soon as possible.

Thanks, Jasem. After the latest update there are no ghost pictures anymore. liveview and thost pictures solved! Unfortunately there is another issue with this driver.

Make sure mirror lock is activated in the camera's settings
Set mirror-lock to 2s in indi
Add a 1,5s exposure to the sequence.
activate the sequence.

Occasionally what happens is this: You can hear the mirror go up, 2s of silence, then the shutter being opened but immediately (significantly less than 1,5s) after that the shutter being closed. Consequently the picture is too dark.

To get logs I did take 5 pictures. Pictures 1 and 5 experienced the problem, pictures 2,3 and 4 were OK. Between these I did nothing but press the + button adding another 1,5s pictures to the sequence and activate it. It appears to me these short exposures happen randomly. I'd guess between 20%-40% of the pictures taken are affected by this issue. Earlier today I did the same test with 4 exposures. In this case every other photo taken was affected.

Jasem, I installed the nightlies a few minutes ago. I still get ghost pictures in both gphoto and canon drivers. The good news is the liveview issue appears to be solved!

Hmmm, I assume should have noted that I did this test running indi_canon_ccd?

I have now done the exact same test running indi_gphoto_ccd and the result is different: I took the first picture, aborted, activated the sequence again and the photo that was shown then was the correct, most recent one. Remarkably, it took longer than normal until the picture appeared.

I then did the same thing again. This time the photo shown was not the most recent one but the one before. The picture didn't
take as long as in the first attempt to show up.

I did the test for a third time and the result was the correct photo again and it took longer to show up just as it was the case in the first attempt.

I have no idea what it all means. I just hope these tests help tracking down the problem.

To be clear, I have not updated my system yet. I'm curious to find out whether your modification has solved the issue.

I have re-produced a ghost picture a few moments ago (Canon 5D Mk2). It goes like this...

Go to CCD & Filter Wheel
set exposure to 5s
add this one to the sequence by pressing +
activate the sequence
you can hear the camera click, starting the exposure.
while the exposure is in progress (before 5s have passed) press the stop button (Status column now shows "Aborted")
no picture is being show
move the camera and point it towards a different object
activate the sequence again
wait 5s until the exposure has been taken
The picture that is now being transferred and shown is NOT the most recent one that you have taken but the one before

now switch the camera off. The camera display will now show something like "recording... remaining pictures: 1"
the camera won't stop showing this message unless you unplug the usb cable.
