BYN crashes when trying to use frame and focus with D800e

[Pixl8tr]

Hello, I am using BYN 1.0.5  with a Nikon D800e on windows 10.    When I try running BYN I can connect to the camera fine, but when I try to use frame and focus the program crashes.  When I try to restart It gets as far as loading the UI then stops again.  At that point I need to reboot the PC.  I did notice a background worker task still running after it crashes when trying to use live view. I ended that task, but I still need to reboot again to run BYN.   I attached the log file for when  BYN stops when trying to use  frame and focus.

 

Has anyone seen this behavior before?

Any Ideas?

 

Cheers!

 

Mike

Ah, that would do it.  90 feet is way out there and yes, live view stream is very demanding.

 

Try this, go Settings and push the live view threshold to 500ms or higher and see if thats makes a difference.  You'll only get 2 fps at 500ms between frames but it make get you working in the mean time.

The backgroundworker is fine and it is not unrelated to your issue.

 

I see this in the logfile.

 

2016-05-05 22:55:48,726 [Main] ERROR - LiveviewImageSize

2016-05-05 22:55:48,726 [Main] ERROR -    at BinaryRivers.Camera.Nikon.PropertyBaseStringEnum.DownloadPropertyFromCamera(String& value, List`1& values)

 

Looks like there is no live view images.  Do you have live view turned off?  If you do not connect your camera to the computer does live view work?

 

Is your camera dial set to a value where live view is not possible?

 

The need to reboot is due to the fact that the Nikon SDK still has a handle on the camera once this occurs is it would release it by the looks of it.

 

Keep us posted,

 I see the live view image and targeting box appear and begin updating for a few seconds, then the program stops working and I get the windows error dialoge box.

 

Is your camera dial set to a value where live view is not possible?  Nope,  set to SingleShot , Manual mode.  I can press the Live-view button on the camera, and it works fine on the LCD screen.

 

The need to reboot is due to the fact that the Nikon SDK still has a handle on the camera once this occurs is it would release it by the looks of it. Yes, I assumed it was some sort of legacy issue with the unclean exit of  BYN.

 

Keep us posted,

I did notice in the BYN logs that Live-view image size  reports back as 'Not Supported"   Is this an issue? 

I will get another cable and see if that may be the issue tomorrow

 

Thanks!

Ok, the more I think about this the more I think this is a bug.  My best guess at this point is that the liveview image data starts at an different offset in the liveview image.  This was the case with the D3 a few months back.  The tricky part is to find what that offset is.

 

It would help if I can get a saved liveview image as a jpg file but I realize that this may be difficult given BYN does not give you one.

 

But, if you go planetary and start a recording with save jpg do you get the jpg images saved in your download folder at least?  If yes send my one of them to support@otelescope.com.

Hi,

Some additional data.

I think it may be my USB extender. ( Startech  usb2 over cat5 extender)  it ( the extender) possibly cannot keep up with the data-stream or some noise/corruption happens and BYN gets disconnected or something.

 I changed the USB cable from the camera to the Startech same thing.  I moved the Camera inside, and plugged it directly into my computer port and no issues at all with live-view or image capture. I tried it with a USB 2.0 hub in between and still it works great.

 So, it must be the USB extender.  It's about 90 feet from my warm room.

 

I will have to figure out a different solution, maybe a small computer at the scope and then remote into that.  

 

Thanks for your help!

Keep in mind that Nikon recommends not using a hub when connecting the camera to a PC.

 

At least as a test I would recommend connecting the camera directly to the PC.

 

Your solution to put a PC in the observatory is also a good choice.
