Allsky Camera

This is the source code for the Wireless Allsky Camera project described on Instructables.

Requirements

In order to get the camera working properly you will need the following hardware:

• A camera (a Raspberry Pi HQ or ZWO ASI)
• A Raspberry Pi (2, 3, 4 or Zero)

Note:* Owners of USB2.0 cameras such as ASI120MC and ASI120MM may need to do a firmware upgrade (This changes the camera to use 512 byte packets instead of 1024 which makes it more compatible with most hardware.)

The Datyson T7 camera seems to be supported as well. The firmware needs to be upgraded with ZWO's compatible firmware (see link above) and you'll need to add this line in /boot/config.txt: program_usb_boot_mode=0

Installation

New: PatriotAstro created a video describing the installation steps below. Feel free to check it out if you prefer video tutorials or if you're new to Linux and Raspberry Pi projects. Another video covers the installation on a Raspberry Pi zero with both ZWO and RPiHQ cameras.

You will need to install Raspbian on your Raspberry Pi. Follow this link for information on how to do it.

Make sure you have a working internet connection by setting it either through the WebUI or the terminal. The WebUI is highly recommended since it simplifies administration of the AllSky software.

1. Start by installing git. You may already have it installed:

   sudo apt-get install git

2. Now fetch the code from this GitHub page. Open the terminal and type the following:

   git clone --recursive https://github.com/thomasjacquin/allsky.git

3. Then navigate to the allsky directory:

   cd allsky

4. Now, run the install script:

   ./install.sh

Update

There is no 1-click update yet so until then, the easiest is to backup your config files, delete the allsky directory and follow the installation instructions again.

Please note that version 0.8 added many new settings and changed the name of several existing settings. For example, there are now separate brightness levels for daytime and nighttime, called "daybrightness" and "nightbrightness". Version 0.7 only had "brightness" that applied to both day and nighttime. It's very important that you save a copy of your current settings prior to upgrading to version 0.8 so you can restore them properly. The WebUI interface uses these new settings so it's also important to update AllSky prior to updating the WebUI.

Also note that in version 0.8, the default image file created and uploaded is called either "image.jpg" or "liveview-image.jpg", depending on how you set things up. The prior "image-resize.jpg" is no longer created. Keep that in mind if you copy the image to a remote web server - it will need to know about the new name.

Some users have reported ASI TIMEOUT errors with their ZWO cameras in verion 0.8. This can often be fixed by changing the "autousb" and/or "usb" settings - see below.

Configuration

Here's a quick overview of the configuration files.

the first one is called config/settings_RPiHQ.json or config/settings_ZWO.json, depending on which camera type you have. It contains the camera parameters such as exposure, gain but also latitude, longitude, etc. Many settings have both a daytime ("dayXXXX") and nighttime ("nightXXXX") version. If you have the administrative WebUI, the files are in /etc/raspap, otherwise they are in ~/allsky/config. The advantage of using the administrative WebUI is that you don't explicitly edit the files, instead, you do it via the WebUI interface, which includes descriptive text on each option.

The exact list of settings available depend on the camera you are using; in general, the RPiHQ camera has less settings.

nano config/settings_RPiHQ.json

-or-

nano config/settings_ZWO.json

Setting	Default	Additional Info
width	0	0 means max width. Look up your camera specifications to know what values are supported
height	0	0 means max height. Look up your camera specifications to know what values are supported
dayautoexposure	1	Set to 0 to disable auto-exposure during daytime. Auto-exposure delivers properly exposed images throughout the day even if the overall brightness of the sky changes (cloud cover, sun, etc). Since daytime exposures are short, there is not daytime "maxexposure". This option is usually only disabled for testing.
dayexposure	0.5	Day time manual exposure time in milliseconds. Normally daytime auto-exposure will be used; if so, this value is used as a starting exposure.
daybrightness	50	Varies between 0 and 600. This setting changes the amount of light in daytime images.
daydelay	5000	Time in milliseconds to wait between 2 frames during the day.
daybin	1	bin 2 collects the light from 2x2 photosites to form 1 pixel on the image. bin 3 uses 3x3 photosites, etc. Increasing the bin results in smaller images and reduces the need for long exposure. Look up your camera specifications to know what values are supported. This variable is usually only changed during the day for testing.
nightautoexposure	1	Set to 0 to disable auto-exposure at night. Auto-exposure delivers properly exposed images throughout the night even if the overall brightness of the sky changes (cloud cover, moon, aurora, etc). When set to 1, maxexposure value will be used as the delay between timelapse frames.
nightmaxexposure	20000	This is the maximum exposure for night images when using auto-exposure.
nightexposure	10000	Night time exposure in milliseconds.
nightautogain	0	Set to 1 to allow auto-gain at night. This mode will adjust the gain of night images when the overall brightness of the sky changes (cloud cover, moon, aurora, etc). Avoid using autoexposure and autogain together as it can produce unpredicatble results (dark frames, but not always).
nightmaxgain	200	Maximum gain for night images when using auto-gain.
nightgain	50	Gain for Night images. Varies from 0 to 600. During the day, gain is always set to 0.
nightdelay	10	Time in milliseconds to wait between 2 frames at night.
nightbin	1	Similar to "daybin" but for night.
nightbrightness	50	Varies between 0 and 600. This setting changes the amount of light in nighttime images.
gamma	50	Varies between 0 and 100. This setting increases or decreases contrast between dark and bright areas. This is not supported by all cameras.
autowhitebalance	0	Sets auto white balance. When used, "wbr" and "wbb" are used as starting points.
wbr	53	Varies between 0 and 100. This is the intensity of the red component of the image.
wbb	90	Varies between 0 and 100. This is the intensity of the blue component of the image.
type	99	Image format. 0=RAW 8 bits, 1=RGB 24 bits, 2=RAW 16 bits, 99=auto (if you have a color camera it will use RGB; mono cameras use RAW16 if the output file is a .png, otherwise they use RAW8).
quality	95	Compression of the image. 0 (low quality) to 100 (high quality) for JPG images, 0 to 9 for PNG
autousb	0	Set to 1 to enable auto USB bandwidth. If you get ASI TIMEOUT errors try changing this.
usb	80	This is the USB bandwidth. Varies from 40 to 100. If you get ASI TIMEOUT errors try changing this up and down.
filename	image.jpg	this is the name used across the app. Supported extensions are JPG and PNG.
flip	0	0=No flip, 1=Horizontal, 2=Vertical, 3=Both
text	n/a	Text overlay that appears below the time, in the same font.
extratext		(ZWO ONLY) The FULL path to a text file which will be displayed under other information. The file can contain multiple lines which will be displayed underneath each other.
extratextage	600	(ZWO ONLY) If using the extra text file then it must be updated within this number of seconds, if not it will not be displayed. Set to 0 to ignore this check and always didplay it
textlineheight	30	(ZWO ONLY) The line height of the text displayed in the image, if you chnage the font size then adjust this value if required
textx	15	Horizontal text placement from the left
texty	35	Vertical text placement from the top
fontname	0	Font type for the overlay. 0=Simplex, 1=Plain, 2=Duplex, 3=Complex, 4=Triplex, 5=Complex small, 6=Script simplex, 7=Script complex
fontcolor	255 255 255	Font color in BGR. NOTE: When using RAW 16 only the first two values are used i.e. 255 128 0
smallfontcolor	0 0 255	Small Font color in BGR. NOTE: When using RAW 16 only the first two values are used i.e. 255 128 0
fontsize	7	Font size
fonttype	0	Controls the smoothness of the fonts. 0=Antialiased, 1=8 Connected, 2=4 Connected.
fontline	1	font line thickness
outlinefont	0	Set to 1 to add an outline to the text overlay to improve contrast.
latitude	60.7N	Latitude of the camera. N for North and S for South
longitude	135.05W	longitude of the camera. E for East and W for West
angle	-6	Altitude of the sun above or below the horizon at which capture should start/stop. Can be negative (sun below horizon) or positive (sun above horizon). 0=Sunset, -6=Civil twilight, -12=Nautical twilight, -18=Astronomical twilight.

timeformat	%Y%m%d %H:%M:%S	Determines the format of the displayed time. Run "man 3 strftime" to see the options.
showTemp	1	Display the camera sensor temperature?
temptype	C	Determines what unit(s) the temperature will be displayed in: C=Celsius, F=Fahrenheit, B=Both.
showExposure	1	Display the exposure time in the overlay? If auto-exposure is enable, "(auto)" will appear after the exposure.
showGain	1	Display the gain in the overlay? If auto-gain is enable, "(auto)" will appear after the gain.
showBrightness	1	Display the brightness level in the overlay?
darkframe	0	Set to 1 to enable dark frame capture. In this mode, overlays are hidden.
notificationimages	1	Set to 0 to disable notification images, e.g., "Camera off during day" if daytime images are not being taken.
newexposure	1	Determines if the new version 0.8 exposure method is used. If you see ASI_ERROR_TIMEOUTs" in the log file, try setting this to 0. ( See issue 417 )
debuglevel	0	Determines the amount of output in the log file (usually /var/log/allsky.log, also can be viewed with journalctl -u allsky).

The second file called config/config.sh lets you configure the overall behavior of the camera. Options include functionalities such as upload, timelapse, dark frame location, keogram. Note that with the administrative WebUI, you can edit the file via the "Editor" link on the left side of the page.

When using the cropping options the image is cropped from the center so you will need to experiment with the correct width and height values. Normally there will be no need to amend the offset values.

In order to upload images and videos to your website, you'll need to fill your FTP or Amazon S3 connection details in config/ftp-settings.sh. If you're using the administrative WebUI you can edit this file via the "Editor" link on the left side of the page.

STARTRAILS_DIR	allsky/startrails/	The absolute path to your startrails directory on the server

Other scripts of interest (in allsky/scripts)

saveImageNight.sh is called every time the camera takes a new image at night. If dark subtraction is enabled, this is where it happens.

saveImageDay.sh is called every time the camera takes a new image during the day.

At the end of the night endOfNight.sh is run. It calls a few other scripts based on your config.sh content.

You normally won't need to edit those files unless you want to implement a new feature. One file you may want to edit is endOfNight_additionalSteps.sh which is where you can place any additional code you require to be run at the end of the night. This script is run prior to the deletion of any old image files.

nano is a text editor. Hit ctrl + x, followed by y and Enter in order to save your changes.

Usage

Autostart

Systemd is used to launch the software automatically when the Raspberry Pi boots up. To enable or disable this behavior, use these commands:

sudo systemctl enable allsky.service     # enables the service, but does not start it
sudo systemctl disable allsky.service

Note:* The service is enabled by default after installation.

When you want to start, stop or restart the program, or obtain status, use one of the following commands:

sudo systemctl start allsky
sudo systemctl stop allsky
sudo systemctl restart allsky
sudo systemctl status allsky

Manual Start

Starting the program from the terminal can be a great way to track down issues as it provides debug information. To start the program manually, make sure the service is stopped (see above), then run:

cd scripts
./allsky.sh

If you are using a desktop environment (Pixel, Mate, LXDE, etc) or using remote desktop or VNC, you can add the preview argument in order to show the images the program is currently saving.

./allsky.sh preview

Graphical Interface

If you don't want to configure the camera using the terminal, you can install the web based graphical interface. Please note that this will change your hostname to allsky (or whatever you called it when installing), install the lighttpd web server, and replace your /var/www/html directory. It will also move config/settings_*.json to /etc/raspap/settings_*.json. Using the Web user interface (WebUI) is highly recommended as it provides additional information on each setting and provides additional system information.

sudo gui/install.sh

Or if you don't want to use the default name of 'allsky' for your pi use the following:

sudo gui/install.sh piname

Note:* If you use an older version of Raspbian, the install script may fail on php7.0-cgi dependency. Edit gui/install.sh and replace php7.0-cgi by php5-cgi.

After you complete the WebUI setup, you'll be able to administer the camera using the web WebUI by navigating to

http://your_raspberry_IP

or

http://allsky.local

Note: If you changed the name of your pi during the WebUI install then use

http://piname.local

The default username is 'admin' and the default password is 'secret'. If this website is publically viewable we suggest you change those settings.

A public page is also available in order to view the current image without having to log into the portal and without being able to do any administrative tasks. This can be useful for people who don't have a personal website but still want to share a view of their sky:

http://your_raspberry_IP/public.php

Make sure this page is publically viewable, i.e., is not behind a firewall.

Note:* The WebUI setup uses /etc/raspap/settings_*.json for the camera settings. If, for some reason, you prefer to go back to the non-WebUI version, make sure to edit your config/config.sh file to have CAMERA_SETTINGS_DIR="${ALLSKY_HOME}/config" instead.

Dark frame subtraction

The dark frame subtraction feature removes hot pixels from night sky images. The concept is the following: Take an image with a cover on your camera lens and let the software subtract that image later from all images taken throughout the night.

You only need to follow these instructions once.

If you don't use the WebUI:

• Place a cover on your camera lens/dome. Make sure no light can get in.
• Set darkframe to 1 in config/settings_*.json
• Restart the allsky service: sudo systemctl restart allsky
• Dark frames are created in a darks directory. A new dark is created every time the sensor temperature changes by 1 degree C.
• Set darkframe to 0 in config/settings_*.json
• Restart the allsky service: sudo systemctl restart allsky
• Remove the cover from the lens/dome
• Enable dark subtraction in config/config.sh by setting DARK_FRAME_SUBTRACTION=true

WebUI method:

• Place a cover on your camera lens/dome. Make sure no light can get in.
• On the WebUI page, open the Camera Settings tab and set Dark Frame to Yes.
• Hit the Save button
• Dark frames are created in a darks directory. A new dark is created every time the sensor temperature changes by 1 degree C.
• On the Camera Settings tab set Dark Frame to No.
• Hit the Save changes button
• Remove the cover from the lens/dome
• Open the scripts editor tab, load config/config.sh and set DARK_FRAME_SUBTRACTION=true

The dark frame subtraction is temperature dependant. Running the dark frame capture while ambiant temperature is varying results in a larger set of darks (1 per degree C). During the night, the sensor temperature is used to select the most appropriate dark frame. Dark frames are only subtracted from images taken at night.

Timelapse

By default, a timelapse is generated at dawn from all of the images captured during last night.

To disable timelapse, open config/config.sh and set

TIMELAPSE=false

Example to generate a timelapse manually:

./scripts/timelapse.sh 20190322

Note: If you are unable to create a timelapse (typically it just dies part way through), try creating or increasing the swap space. 2 GB is a good amount. See https://pimylifeup.com/raspberry-pi-swap-file/ for details. If that doesn't work, try reducing the size of the timelapse video. This is especially true for Rasberry Pi 3 users who have less RAM memory than a Raspberry Pi 4.

Keograms

A Keogram is an image giving a quick view of the night activity. It was originally invented to study the aurora borealis. For each image taken during the night, a central vertical column 1 pixel wide is extracted. All these columns are then stitched together from left to right. This results in a timeline that reads from dusk to dawn.

To get the best results, you will need to rotate your camera to have north at the top. That way, using a fisheye lens, you end up with the bottom of the keogram being the southern horizon and the top being the northern horizon.

Note that it will only show what happens at the meridian during the night and will not display events on the east or west.

The keogram program is used by the scripts/endOfNight.sh script.

The program can take multiple arguments:

Usage:  keogram -d <imagedir> -e <ext> -o <outputfile> [<other_args>]

Arguments:
-d | --directory <str> : directory from which to load images (required)
-e | --extension <str> : image extension to process (required)
-o | --output-file <str> : name of output file (required)
-r | --rotate <float> : number of degrees to rotate image, counterclockwise (0)
-s | --image-size <int>x<int> : only process images of a given size, eg. 1280x960
-h | --help : display this help message
-v | --verbose : Increase logging verbosity
-n | --no-label : Disable hour labels
-C | --font-color <str> : label font color, in HTML format (0000ff)
-L | --font-line <int> : font line thickness (3)
-N | --font-name <str> : font name (simplex)
-S | --font-size <float> : font size (2.0)
-T | --font-type <int> : font line type (1)

Font name is one of these OpenCV font names:
        Simplex, Plain, Duplex, Complex, Triplex, ComplexSmall, ScriptSimplex, ScriptComplex
Font Type is an OpenCV line type: 0=antialias, 1=8-connected, 2=4-connected

If your camera is not aligned in the north-south direction, you can use the optional -r | --rotate option to derotate the image before processing (rotation angle counterclockwise).

Example when running the program manually:

./keogram -d ./images/20180223/ -e jpg -o ./images/20180223/keogram/keogram.jpg --rotate 42 --font-size 2

To disable keograms, open config/config.sh and set

KEOGRAM=false

Startrails

Startrails can be generated by stacking all the images from a night on top of each other.

The startrails program is used by the scripts/endOfNight.sh script.

The program can take arguments:

Usage: startrails [-v] -d <dir> -e <ext> [-b <brightness> -o <output> | -s]

Arguments:
-h : display this help, then exit
-v : increase log verbosity
-s : print image directory statistics without producing image.
-d <str> : directory from which to read images
-e <str> : filter images to just this extension
-o <str> : output image filename
-S <int>x<int> : restrict processed images to this size
-b <float> : ranges from 0 (black) to 1 (white). Default 0.35
        A moonless sky may be as low as 0.05 while full moon can be as high as 0.4

Example when running the program manually:

./startrails -d ./images/20180223/ -e jpg -b 0.15 -o ./images/20180223/startrails/startrails.jpg

To disable automatic startrails, open config/config.sh and set

STARTRAILS=false

Automatic deletion of archived nights

In order to keep the Raspberry Pi SD card from filling up, 2 settings have been added to config/config.sh. Automatic deletion is enabled by default and will keep 2 weeks of data on the card.

AUTO_DELETE=true
NIGHTS_TO_KEEP=14

Modify these values if you wish to increase/decrease the number of nights to retain on the card. Set to false to keep all nights (requires manual management of SD card free space).

Logging issues

When using the allsky service, issues are written to a log file. In case the program stopped, crashed of behaved in an abnormal way, you can take a look at this log file:

tail /var/log/allsky.log

Compile your own version

If you want to modify a compiled file, you'll need to edit the corresponding src/*.cpp file and run the following command from the src directory:

make all
sudo make install

This will compile the new code, create a new binary, and copy it to the top level allsky folder.

Show your sky on your own website

If you have set the upload options to true in config/config.sh, that means you probably already have a website. If you want to display a live view of your sky on your website like in this example, you can donwload the source files from this repository: https://github.com/thomasjacquin/allsky-website.git.

If you want to host the website on the raspberry Pi, run the following command. Note that this website is installed on the same webserver as the WebUI. Currently, reinstalling the WebUI will wipe your website.

website/install.sh

And set these variabled in ftp-settings.sh:

PROTOCOL='local'
IMAGE_DIR='/var/www/html/allsky/'
VIDEOS_DIR=`/var/www/html/allsky/videos`
KEOGRAM_DIR=`/var/www/html/allsky/keograms`
STARTRAILS_DIR=`/var/www/html/allsky/startrails`
