Background

While the Nikon D300s camera will record videos, it's very hard to use.  Mainly because the eye-level finder goes black when in live-view mode.  In live-view mode the only way to see what the camera sees is to either look at the LCD on the back of the camera or use an external HDMI monitor, neither of which is practical for hand held camera shooting.  In order to focus on the LCD monitor I need to hold the camera at arm's length which results in shaky images.

I've looked a handycams and camcorders but to get the features I'd like they seem to be over $2k.  I just stumbled on an ad for the GoPro (Wiki) Hero 5 Black and it seems to offer most, if not all, the features.  I've got one on order.

There are three models similar to the Hero5:
Hero5 Black has the front LCD screen and a larger rear screen. (MSRP $400) Has: Touch display, built-in GPS, RAW & WDR photos and all of below features.
Hero5 Session has no front LCD and smaller rear screen (MRP $300) Has:  Voice control, video stabilization, auto upload to cloud.
Hero Session looks very similar to the Hero5 Session (MSRP $200)

Note the Hero5 Black is similar to the Hero Session but the Session does not have the front LCD screen.  The front screen will tell you what's going on when the rear screen is dark. MY guess is that to really use the Session you need to couple it to a smart phone.

GoPro Hero5 Black

These are intended for sports video photography, but can be used for all kinds of things.
YouTube: GoPro HERO 5 BLACK Tutorial: How To Get Started (mine has minor differences from the video, but pretty much the same)

Start-up

Remove camera from frame and install battery then micro-SD card.

3 red LEDs
If you install the micro-SD card then the battery 3 red LEDs will turn on. 
To fix that remove battery and micro-SD card, press MODE button for a few seconds, then
Install battery THEN install micro-SD card.

A new camera ships with the battery at about 10% charge which is a very good thing to do since the life of a Lithium battery is decreased by hours stored times percent of charge (and temperature).

When you log in at gopro.com and enter the serial number of your camera it will ask if you want to install the latest firmware.
My cell phone does not work at home and Quick for Desktop v2.5.2 only runs on WIN10 - I'm using WIN7 and do NOT want to use WIN10.

The GpPro app for Android phones is a way to upgrade the camera firmware since the phone can connect to both the camera and the house WiFi.

Imaging Chip Field of View (FOV)

The chip has 12 Mega pixels and is 4.5 x 6.2 mm in size. 
The "normal" lens for a 35mm film camera is 50 mm, which is slightly longer than the diagonal of the 24x36mm frame.
The diagonal of the GoPro Hero5 Black is 7.66mm so the "normal" lens would be about 8  mm focal length.  Instead they come with X1.75, 2.6X or 3.5X

Lens Focal Length and aspect ratio.  Wide is 14 mm, Medium is 21 mm and Narrow is 28 mm.
For astrophotography the shutter speed to avoid star trails is 600/FL

Note in the table below that the raw chip is in 4x3 format and to get 16x9 format pixels are thrown away (they may be distored to fit?).  So for the largest number of active pixels use 4x3 format.
If the pixels map 1:1 then the 4x3 modes use the highest number of pixels.

Still & Video Modes

In still mode you have many options that should allow taking photos of the night sky in time lapse mode showing some number of stars.  How many start remains to be seen.

I made a 1 minute 11 second video of rain-hail in 4k - 60 fps.  The file size is 262,767 KB.  When attempting to upload to YouTube the time remaining started at about 1 hour 17 minutes, but the minutes kept getting larger so canceled upload.

Still and video files can be transferred from the GoPro to a desktop computer by using the supplied 22" USB-A to USB-C cable. I have a 6' cable on order.

Night Lapse Mode

I haven't got this to work yet.  My first try failed in that the camera just shut down probably because the battery died.  That should not have happened since the camera was connected to a 2 Amp Hour Power Bank using the GoPro factory USB cable.  The Power Bank had 80% charge the next morning.  See Fig 8 below.  It may be that the power bank was not supplying power.  The power banks typically shut themselves off if there is no load for some amount of time.  This may be a problem since a fully charged camera will not draw much power. I have a USB-C LCD charging monitor tester on order to confirm that the Power Bank is providing power.

The Power Bank I used (not the ANNKE) does not supply power to a charged camera.
The ANNKE Power Bank does show a + sign in the battery symbol on the front of the camera, so it's working as expected.
A daylight time lapse was started 2018 March 19 1:27pm to see if the ANNKE power bank works for this application.  When taking photos of the setup the rear LCD was black and the front LCD just showed the battery. Pressed button on ANNKE and shutter release on camera, not battery shows "+" and rear LCD shows image.  1:35 pm now.  1:45 heard 5 rapid beeps, so expect camera shut itself off.  So the daytime time lapse mode needs some setting that's not part of selecting that mode.  The file size is 2,249KB and when played runs in a fraction of a second. There are only 10 frames (based on the difference between start and end times). Note the camera's battery has plenty of charge.

So . . .  to get time lapse to work you also need to find and disable "auto off" or whatever GoPro calls that function.  You'd think that selecting time lapse would automatically disable that feature.

Auto Off

If left alone and not recording after some time the camera makes 5 quick beeps and shuts down.

Lack of Support

This is an ongoing problem.
Just now I was trying to post a question on the GoPro support web page, but had a problem with my password.  After resetting it and finally getting logged in the window changed into:
_______________________________________________________

HTTP Status 500 -


type Status report

message

description The server encountered an internal error that prevented it from fulfilling this request.

________________________________________________________

The problem was the camera turning itself off, see: Night Lapse Mode above.

Another problem is understanding the LCD icons on the front and rear screens.

Literature

The manual included is written is very small font type and is grey not black so impossible to read without a microscope.
The on line Hero5 Black manual is much better, but I can not find out what the three LED are for.

Patents

Nicholas D. Woodman (Wiki) was the man behind the GoPro cameras and many of the early patents are in his name.  The first application was surfing off Australia.
