BYN D5300 Notes


lodrigj

Question

Hi Everyone,

 

I just started using BYN v2.0.1 with a new Nikon D5300 and here are some notes and observations I made... in no particular order... and please note these are not complaints about BYN at all. Honestly, I don't know how Guylain deals with Nikon and the changes from camera model to camera model, and the Nikon SDKs.

 

The error message on a failed connect refers to Canon camera numbering 40D, 60D, 80D "use the app in Windows Vista SP2 compatibility mode" and "40Dx, 50D 70D and D3### are not supported".  With Nikons, the D comes before the number as in the D3### listed.  No big deal, but it might be confusing to some people.
 
In Planetary mode, I'm getting 30fps for full frame and only 5 fps at 5x.  I'm certain this caused in the camera as live view slows down terribly on the back of the camera when magnified even when BYN is not connected.
 
The display in BYN seems blurry in Live View, probably because of the JPEG compression - the JPEG live view files are only 33k. Again, this is caused by the camera and not BYN.
 
The live view planetary resolution at 5x is, unfortunately, not even close to 1:1 (I just definitively tested this). Combined with the extremely high JPEG compression used, this makes the D5300 pretty bad (as in basically unusable) for high-resolution planetary imaging.
 
You can't control lens focus with a Nikon autofocus lens through BYN. I guess this is not available in the SDK?
 
In BYN in "Main Imaging Mode" , AV is available under "shutter", but it doesn't work. Neither does Program.
 
Time goes into spinning "busy" icon in BYN at top right, but nothing happens and abort doesn't work, you have to kill the program.
 
Sometimes BYN does not write the image file to the camera, because it switches on its own, and without warning, from writing to PC + Camera to just PC. ... YES I'M SURE it was set to PC + Camera initially.  This happened for sure in studio tests done inside today.
 
This also happened to me the other night under the stars, and I liked to poop my pants when I could not find 2 hours worth of Horsehead exposures on the camera's memory card. Luckily they were written to the PC.  But there's some weird behavior going on here.

Fixed in next release.

Yes, sadly frame rate is 100% dependent on how fast the camera makes them available to the SDK.

Correct, live view frames are highly compress as provided by the SDK.

True for some models.  Nikons differs here form Canon.  Nikon has what they call a zoom factor that goes from 1 to 3 and up to 6 on some models, maybe higher on some models.  BYN takes the highest possible zoom factor stopping at 5.

No, this is not implemented in BYN as of yet.

 

In BYN in "Main Imaging Mode" , AV is available under "shutter", but it doesn't work. Neither does Program.

Ummm, this may be a bug.  I’ll look into it.

 

Time goes into spinning "busy" icon in BYN at top right, but nothing happens and abort doesn't work, you have to kill the program.

Can’t troubleshoot this without knowing what actions were taken leading to this behavior.

Sometimes… always actually.  Nikon does NOT allow saving images to card while connected to a PC.  This is true for almost all models.  Nothing can be done here with the current SDK.

Hi Guylain, The D810a was not really usable for high-resolution planetary either because of the high compression ratio.  I think that's a killer separate from the zoom level, and I suspect all of the Nikons may be like that.

Just set it to "Time" and try to take a picture. Thinking back, it may be because "Time" requires two shutter presses, one to open the shutter and one to close it.

Hmmm... that is really curious then, because I definitely have both JPEG and Raw files saved to the memory card in the camera, as well as to the laptop, when connected to a PC. Many in fact. That's why I thought it was so odd when I didn't find some RAWs, but the JPEGs were there on the memory card in the camera.

Hi Jerry,

 

I'm not sure if the D5300 is one of those camera that does not allow saving to camera.  According to your info it seems like it does.

 

The saveto card is part of the capture plan.  Is it possible that for one plan you selected PC+Card and for another plan you selected PC only without even noticing it?

 

The log file will show what this value was for each image taken.

 

Regards,
