Nikon Z6 Frame And Focus

Question

I was trying to use my nikon Z6 with backyard nikon. It connected but when I tried the frame and focus it did not work  I had image in my camera but never got live view in the computer.

Everything else works fine and was able to image in spite of the problem with frame and focus. (Got best focus possible in the camera screen)

IS there any way to fix this?

I've too found the back screen on the Z6 gives a better live view image then F&F in BYN. F&F works but really only shows the brigtest of stars, I think something is being applied to the raw image when its sent to the computer or something.
Also of note, the stacking generally just blows out the image after 3 while providing no additional real detail (stars you see at level 1 are just brighter as you go up levels and the background noise blows out the image), not sure if that is how its suppose to work or a limitation due to Z6 output but I had though stacking should kick out some additional detail not just make the image brighter & noiser.

It would be nice if we could add a dark subtraction frame to F&F to drop the noise floor (or if that feature already exists a friendly pointer on how to do that).


Camera Dial to M, Stock Firmware (first version), BYN release with Z6 feature - I havent updated anything for fear of getting issues one way or the other.

LiveView images are not raw images, they are JPG images that are scaled to fit on the LCD display. I do not believe that BYN does any processing but just displays what it receives.

If the camera supports exposure simulation of LiveView images then you can reduce the noise in the image by lowering the ISO.

Most of the noise in your LiveView frames is not random thermal noise, but skyglow, so even if you could apply dark frames on the fly, it would not reduce the background mottling that you are seeing. I am not sure, but I believe that BYN's stacking algorithm is purely additive.

The increase of background mottling in F&F images as a result of stacking should not be a problem since these images are not "keepers". They are throwaway images used for focusing and target framing. The exposure time of F&F frames is only a few milliseconds long so if you want to see more detail in the image then you need to lengthen the exposure time by shooting snap images.
