Live view is AS-IS coming from the camera.  BYN makes to attempt to alter it so there is not mush BYN can do.

However, it would help to understand what you mean by horrible.  What ISO are you using?  What is the ambient temperature where you are? Etc...

You say you can see perfectly on your camera LCD... the live view frame in BYN is the exact same data with no alteration... aside that it is bigger of course.

The difference is probably the settings (exposure and ISO) in the camera when LiveView "worked" vs. the settings that you have told BYN to use. When you activate LiveView the settings in BYN are set into the camera. You need to set them appropriately.

The devil is in the details.

Ok I’m missing something here. I turned off max sensitivity so I can change the ISO. I have tried every ISO setting and everything that I look at is total noise. If I get a really bright star it is impossible to look at the screen and focus the camera. Now I have not messed around with exposure (camera is always in Bulb)

When you see "total noise" as you put it... can you confirm you see the same thing on the camera LCD screen.  It should be the same.

Nikon cameras do not work the same as Canon where the later has an "Exposure Simulation" feature and works relatively well.  Nikon on the other hand it is hit and miss. 

Older Nikon do not allows changing values while in live view; you need to pause liveview in BYN, make your changes, and resume live view.  Make sure you select a time value < 2 second, it will not work in BULB mode so change to manual or S mode.

On newer high-end models you need to activate exposure simulation this way; disconnect the camera from the computer, activate live view, and press the OK button to activate live view simulation.  Once it is activated it stays activated so using BYN afterwards will have live view simulation activated and changing shutter speed and aperture (if a lens is connected) does change the live view image.

Try that on your camera and see if it makes a difference.

This option is only on some selected high end models.

There is absolutely no need to wait for a break in the clouds to test LiveView with your D5300.

Simply set your laptop up on the kitchen table, put a lens on the camera, and connect the USB cable between the two devices. Then turn the camera on, put it in manual mode, and fire up BYN.

You can now test to see if you are able to control the brightness of your LiveView images in BYE by adjusting the exposure and ISO of the camera. As Guylain has said, be sure to set the exposure to 2 seconds (Not Bulb with a duration of 2) and be sure that you have Exposure Simulation enabled in the camera.

As Guylain said, with your camera you need to pause LiveView, change the ISO or shutter, and resume LiveView in order to see any change.

My Canon doesn't have an exposure simulation setting, but it works nonetheless. I just set the Shutter to 2 seconds and the ISO to maximum to brighten my LiveView as much as possible. It has a lot of noise, but this does not impact the ability to focus.

Your Nikon should be simple enough to test with a lens on the camera. Set the f/stop to the highest number for the lens. Set the ISO to 100 and select 2 (seconds) from the Shutter dropdown in BYN. Then start LiveView. Pause LiveView and change the ISO to 200. Resume LiveView. Rinse and repeat.

As you keep increasing the ISO, the image should brighten. If it is already too bright then reset the ISO to 100 and shorten the Shutter to 1/100 and repeat. If the brightness of the image doesn't increase as you go through the process then I think that you will have to do what imagers who use cameras without LiveView or something similar do. That is focus with Snap images (short still exposures) taken from the Frame & Focus screen, while adjusting focus. I would start with an exposure of 2-3 seconds and see what you get.

Can you post a print screen of the live view where you say it is horrible?  Also, it would be nice to have a print screen of the other app you say it is good.

When I get home tomorrow night. The apps that work are qDslrDashboard, Helicon remote and the Nikon software Wireless utility
