I find that Ekos can't handle taking bias/flat frames with my D850.  I set a delay of 10 seconds to let it have enough time to download and save the files.  However, it bypasses the delay during these shots and attempts to do them as fast as possible.  This saturates the bus and I get unspecified file write errors until it eventually crashes. 

Is there a better way to shoot bias/flats?  I've tried the 'just let the camera do it'.  The issue is the file sizes aren't the same;  my nikon saves them at one size when they're raw; gphoto says they're another size.  

Ekos for some reason ignores the write time for saving the file; it's normally not an issue with multisecond exposures.  

Here are the logs:
2022-01-30T17:37:51: [ERROR] Exposure failed to save image... Unspecified error 
sure. 
2022-01-30T16:10:05: [WARNING] Camera image size (8288x5520) is less than requested size (8856,5504). Purge configuration and update frame size to match camera size.

Help please!

 

It's interesting. I had it set to "force bulb" which states that if it's a subsecond exposure, it'll use the presets on your camera. But, when I did that it would crash out with the unspecified error above. But, if I go into the INDI driver, select a preset exposure time to match what Ekos calls for, it'll work.  That does not work for bias frames however.  It can't correlate it to a proper exposure... and it'll crash out as before.

If, I do the minimum 1/8000s exposure for a bias singularly, it will take them.  It's just the follow-on timing that seems to cause some type of error.

Is there some 'max pixel' height and width in Ekos?  Why does my camera show 8288x5504 when the full array, even in the driver, is 8856x5504?  I can't put my figure on why Ekos would choose that value.
