Oops I posted the exact same thing below without seeing your post. Just here to steal thunder today :blush:


He could use a wedge...


Hi Chris, I definitely very interested in DYI wedge. I’m new to astrography, and want to slow down before spending another $1-1.5k on GEM. I still struggle with basic camera configuration and mount tracking. As soon as I can I will try this DYI wedge, and if was not successful I should just go and get GEM ;)


Thank you
Mohamed

Note that for the capture target I had SD card, the had Delete SD image checked. I still had the imaging sequence set to save to StellarMate, so no images were actually lost.

I used these settings successfully for several months until I switched to a Cooled CMOS camera.

Main Control:
Mirror Lockup = 0 (It I set the mirror lockup on it would fail, and I would need to reboot the system and restart KStars on the Mac)

Options:
Force Bulb = OFF (Camera was set to Bulb mode, if I used Force Bulb it would fail)

Image Settings:
Capture Format = RAW
Transfer Format - Native
Capture Target = SD Card (I think this one was the key in the Image Settings tab)
SD Image = Delete


Thank you rdricks. I think the driver configuration was the issue. I was able to take 30 shots 300 seconds each in one session without a single error. Here is what I've done and configured (for future reference of similar problems)

1. Upgraded my camera firmware from 1.0.2 to 1.0.3 from Canon website
2. Used the Canon DSLR driver
3. Main control -> Mirror lock = 1 sec
4. Options -> Force bulb = OFF
5. Image settings:
- Image format = RAW
- Transfer format = NATIVE
- Capture target = SD CARD
- SD Image = DELETE


As I changed many parameters, I really don't know which one was essential to fix the problem, but I'm glad it worked.

One last thing, when I configure the driver and press save for the configuration, it gives me a message that it saved, but when I reopen ekos/indi again, I only see the defaults. Is there is a way to keep my settings?


Thank you
Mohamed

I checked, and the verbose was checked. I did another try with the canon driver as Jassem did, but again the same results. Also, I attached a picture of my camera configuration screen that I currently use. Maybe it is one of the camera settings.

Do you know what event the ekos driver was waiting for before it shows "failed to expose"?

My problem is not tracking at all. The internal guides was not able to connect to the mount.

I want to share what I tried so far:

On the mount hand control, I changed the tracking mode to EQ North. I do quick alignment using a solar object, I start ekos and connect indi. I did my trial using a guide simulator camera, and it was able to connect to the scope and guide it.

I ordered OAG (should work better with SCT according to some advises and online research), and I will continue to update this thread with what I got after using it.


Thank you

GM Jassem, which driver did you use? The Canon DSLR or GPhoto?

Also how I can check if I have the latest ekos/indi versions?


Thank you

Hello Ihoujin

Thank you for your reply. I did try the GPhoto driver. It worked well for the 1st 300-sec picture but it gave the same error on the 2nd capture.

Attached is the log file for the GPhoto and screenshot for my configuration.

Any idea what went wrong here?

Edit: Also Camera needs to be in Bulb mode for longer exposures.


Thanks, but how I can switch the driver? I choose Canon DSLR from the drop-down list as my CCD camera in ekos configuration.

Bulb mode: I always use bulb mode

Thank you
Mohamed

Hi Ihoujin

Thank you for your reply. I was able to create the log file with all details including driver debugging, and emulate the problem... PFA and let me know what do you think.

PS: my camera firmware is 1.0.2

thank you

Hello

I ran into a problem yesterday which is my Canon 600D was failing periodically every other image to capture images with the error message "Failed to expose". I found that this only happens with long exposures (300 seconds) but not for the sort 30 seconds ones...

I tried to enable the debug log, but as soon as I enable it and connect to the driver, it automatically switches to Debug disabled, so I only have the regular verbose output as attached. I looked into the forums, but the only related problem was due to a new build and noise reduction function that I don't have.

Any help would be appreciated...

Thank you
Mohamed

Hello wvreeven,

I was able to make it visible as selection by setting the tracking mode to EQ North (i have AltAz mount).

Now the problem is that the internal guider keeps failing. PFA the logs from today's session...
