Dropped frames with ASI585MC longer exposures

#1

Post by smm31 »

Just received an ASI585MC and found that when SC starts in Live at any exposure <999 ms, it seems to work normally, but at >=1000 ms, it immediately begins dropping all frames and shows no image. Have not extensively examined other settings, but manipulations of the gain or histogram don't appear to have any effect. Reducing the exposure time does not restore frame capture, but reducing it, then turning live view off then on restores the capture. Longer single frame and Live stack captures fail as well. Basic long captures do seem to work in ASIImg and ASILive. Latest SC version, ZWO and ASCOM drivers; works fine with my ASI178MC and ASI120MM; same behavior on two computers, win10 and win11. A
Thanks for any help!

Re: Dropped frames with ASI585MC longer exposures

Post by admin »

Hi,

well, the difference is that SharpCap switches the camera from video to still mode at (if I recall correctly) an exposure of 2000ms or above. Still mode is obviously not working well for you, but video mode is :(

This isn't usually an issue for ZWO cameras, so I don't have a ready suggestion of what to do to fix. It would probably be worth doing the usual checks of making sure your ZWO system drivers are up-to-date and also checking the various suggestions in the USB troubleshooting section (see link in orange 'Forum Rules' section above) as USB transfer issues could cause this sort of problem. It would be worth trying RAW8 mode to see if that behaves differently too (obviously not where you want to be for imaging, but just to try to find the full scope of the problem). If you can, try a different PC with a different USB cable too - just now and then you find a PC where there is an odd incompatibility with some cameras.

cheers,

Robin

Has there been any resolution to this? I recently bought a ASI585MC and am experiencing the same problem, the camera does not work when exposure is set greater than 1 second and switches to still mode. I watched the logs to confirm this behavior. I swapped cables, used USB2 and USB3. I have not yet tried another computer. However, the camera works fine with using the ASI Capture apps (yuck). I have have an ASI224MC which works fine with SharpCap.

I will run through the 'Troubleshooting USB issues' as well as try another computer and report back any findings.

thanks for your help!

Hi folks,

please check that you are using the very latest version of SharpCap (4.0.9208 or newer) - in that version I have included a new update to the ZWO SDK, and it's just possible that the update will resolve this issue.

cheers,

I am 99.999% sure you are correct, I must have had an older version of 4.0 installed on my laptop.

Before I read your recommendation I installed Sharpcap 4.0 on my desktop PC running Win 11. I attached the ASI585MC and everything worked fine, both long and short exposures. I then de-installed both Sharpcap and the ZWO camera drivers from my laptop, followed by a fresh download and install of both. A quick test revealed that everything is now working fine on my laptop as well. I never did check to see what version of Sharpcap 4.0 I had previously installed on my laptop, but the de-install and fresh download and install must have fixed the problem by installing the latest version. Root Cause Analysis - Operator Error :roll: Sorry for the hassle and thank you for the quick response!

Hi Chris,

no worries - glad to hear that the latest version sorts it.

Hey all, I was reading through this and last I saw there was an update and it seems to have resolved for the ones posting. I just downloaded SharpCap 2 days ago and I was having the exact same issue with my ASI585MC last night. Any insight on this?

Hi,

can you just confirm exactly which version of SharpCap you are using and which version of the ZWO drivers? There is some suggestion above that maybe the drivers have a role in this too.

The latest ZWO camera driver looks to be version 3.21 from December 2022 (download from https://www.zwoastro.com/downloads). The latest SharpCap versions are 4.0.9545 or 4.1.10427 (beta version).

cheers,

Thank you for your quick response! I was able to confirm I have the correct versions of both SharpCap and the ZWO drivers. I went ahead and double checked LX mode was checked. I decided to try to run another sequence of 29 frames at 366s and 195 gain to simulate the night I was getting the failures. When I was setting up my run just now, I followed this sequence which is exactly what I did the failure night and differences from then to now are marked in parenthesis:
Capture
Number of frames ticked and set to 29
Click on deep sky
Capture setup tab:
Capture in set to RAW16
Capture to set to TIFF
Capture list:
Light
Number of frames set to 29
(Ticked override exposure and set to 366) I did not do this on the failure night
(Ticked override gain and set to 195) I did not do this on the failure night.
Camera settings tab:
Set the default exposure ticked
Set the default exposure ticked and set to 366
Set the default gain ticked and set to 195

There was a setting that I cannot find now which had something along the lines of delay between frames and I had that at 1 second and switched it to 5 seconds.

Hi,

I'm afraid I can't quite work out from your latest post above if you had any more success with the latest attempt or not, sorry.

Another thing worth checking is USB issues (see the link to 'Troubleshooting USB issues' in the orange box at the top of this page). If you are using USB extension cables or hubs that can lead to unreliability which would give dropped frames.

cheers,

Robin
