The process for installing indi-allsky is documented in the wiki.
https://github.com/aaronwmorris/indi-allsky/wiki/Getting-Started
indi-allsky has full support for running in a containerized environment. Check out the docker/ folder for the Docker assets.
https://github.com/aaronwmorris/indi-allsky/wiki/Docker
- When indi-allsky is run from the command line, logs are sent to STDERR by default.
- When the indi-allsky service is started, logs are sent to syslog via facility local6. Logs are stored in
/var/log/indi-allsky/indi-allsky.logand rotated daily.- Web interface logs are located at
/var/log/indi-allsky/webapp-indi-allsky.log
- Web interface logs are located at
indi-allsky updates are designed to be rolling releases. I do everything I can to prevent breaking changes. Most changes only require pulling updates from GitHub and re-running setup.sh.
https://github.com/aaronwmorris/indi-allsky/wiki/Updating-indi-allsky
In an effort to increase security, I am trying to do a better job of tracking security issues in indi-allsky and the associated Software Bill of Materials. GitHub Dependabot alerts are enabled which help track things like vulnerable Python modules.
https://github.com/aaronwmorris/indi-allsky/wiki/Security-considerations
https://github.com/aaronwmorris/indi-allsky/wiki/Security-Notifications
libcamera is a new camera interface designed to replace the legacy camera interfaces such as V4L2.
Proper libcamera support is only working on Raspberry Pi OS 11 (bullseye) on Raspberry Pi 3 & 4.
https://github.com/aaronwmorris/indi-allsky/wiki/libcamera-enablement
Note: Genererating and processing raw (dng) files on a system with less than 1GB of memory and libcamera will cause out-of-memory conditions. There is an option to generate JPEG or PNG files with libcamera which solves this issue.
indi-allsky fully automates the capture and processing of master dark calibration frames. Currently, sigma clipping and average methods are supported.
https://github.com/aaronwmorris/indi-allsky/wiki/Dark-Calibration-Frames
This is a special night time operating mode intended to reduce gain when the moon is more illuminated and above the horizon
Keograms are a visual representation of the entire timelapse video in a single frame. Every image is rotated so that the vertical aligns to the meridian and then the center-vertical column is extraced from each frame and compiled into the keogram. The rotation parameter in the config is KEOGRAM_ANGLE
https://github.com/aaronwmorris/indi-allsky/wiki/Keogram-Rotation
Below you can see perodic clouds passed over between 8-9pm and again between 4-5am. If you look closely enough, you can see the Pleiades star cluster and the Orion constellation as it passed through the meridian in this example keogram.
Note: The horizontal lines are just hot pixels that were subtracted by the dark frame.
Star trail images stack the stars from each frame to show their progression across the sky.
Video of the star trails being stacked in real-time!
indi-allsky polls data from NOAA Office of Satellite And Product Operations to report the level of smoke coverage in your location. The OSPO provides KML map data for their Hazard Mapping System Fire and Smoke Product [HMS]. indi-allsky processes the smoke polygons in the KML map data and checks if your location (~35 mile radius) is contained within the smoke areas.
Smoke data is updated every 3 hours from NOAA. Smoke data is also published with the MQTT data.
Note: Data is only available for North America.
indi-allsky utilizes data from NOAA Space Weather Prediction Center to predict the possibility of Aurora in your location. The SWPC provides data using the Ovation Aurora Model for aurora predictions. indi-allsky uses the Ovation data to create an aggregate score within a ~500 mile radius around your location.
The current Kp-index value is also polled from NOAA. This is the measurement of the disturbance of the Earth's magnetic field, ranging from 0-9. Values higher than 5 are good indicators of stronger solor storm activity which creates aurora.
The Kp-index data, combined with the Ovation data, gives an objective prediction of the visibility of Aurora for your location.
Aurora data is updated every 60 minutes from NOAA. Aurora data is also published with the MQTT data.
Satellite tracking data is used to track the visibility of specific satellites like the International Space Station and Hubble Space Telesope. Rise, transit, and set times are available in the Astropanel view.
Orbital data is downloaded in TLE format from CelesTrak
indi-allsky utilizes OpenCV pattern matching to detect and count the number of stars in the view. Star counts are a good objective measurement of sky conditions.
Star and meteor detection support using detection masks to customize your Region of Interest if there are obstructions in your view. https://github.com/aaronwmorris/indi-allsky/wiki/Detection-Masks
Using OpenCV Canny edge detection and Hough Line Transform, indi-allsky is able to perform basic line detection to detect meteor and fireball trails in the view. Airplane and satellite trails are also detected using this method. Images are tagged with an asterisk in the image viewer if a trail has been detected.
Focus mode is a special setting that generates images more often and implements a Variance of Laplacian scoring algorithm on the image to assist with focusing the camera. Images are not saved when focus mode is enabled.
indi-allsky supports image stacking to increase details and contrast in the image.
The following stacking modes are provided:
- Maximum - The maximum value of each pixel in the stack is used. Increases contrast of stars and sky overall. Extends the effect of satellite/airplane trails, meteors, and other phenomena.
- Average - The average value of each pixel is used in the resulting image.
- Minimum - The minimum value of each pixel is used. This has the effect of removing airplane and satellite trails (and meteors).
The Stack split screen option will split the image into two panes. The left pane will show the original image data and the right pane will contain the stacked data.
Regarding performance, stacking does have an impact to memory and CPU utilization. indi-allsky stores the RAW images used for the stack in memory. A single 1920x1080 (1K) image is approximately 8MB. Four 1K images will require 32MB of memory. A single 4056x3040 (4K) RAW image is ~25MB, four would require 100MB of memory (at all times).
CPU utilization and memory is reasonable for stacking 1K images on Raspberry Pi 3 (1GB) hardware, but 4K stacking starts to significantly impact response times. Strongly recommend Raspberry Pi 4 with 2+GB of memory for 4K images.
Registration (alignment) requires significantly more CPU time and doubles the memory requirement since the registered images must also be stored in memory. Registering one 1920x1080 (1K) image (reference + image) requires 2-3 seconds on Raspberry Pi 3 hardware.
The indi-allsky web interface is built on the Flask MVC framework. It is designed to be a dashboard for your sky. Included is the ability to fully manage the camera configuration without having to manually edit from the command line.
Most views do not require authentication. Credentials for accessing the privileged areas are defined upon the first setup of the software.
Early evening, the sun was still going down, but a cloud passed by, increasing the average brightness and lowering the star count.
A large cloud passed over significantly increasing the brightness of the sky and blocking out almost all of the stars.
Historical images browsing.
Pictured: A small satellite flare.
Historical Star trails and Keograms. The Keogram image is linked directly to the timelapse video for the night.
All media generated are logged in a local SQLite database stored in /var/lib/indi-allsky/indi-allsky.sqlite This database is used as the source of images for timelapse and keogram generation, as well as, for displaying images via the web interfaces.
The database is managed via the python modules SQLAlchemy and alembic to provide migrations (schema upgrades) automatically in the setup.sh script.
An on-premises indi-allsky system can synchronize images and timelapses to a cloud-based indi-allsky web server instance using the built in SyncAPI. Remote users can browse the remote indi-allsky web instance without touching the system running the camera. Images are synced in real-time.
In effect, the indi-allsky web interface is its own remote web portal.
A remote indi-allsky instance can support multiple clients using SyncAPI with a single instance. Users can easily switch between the cameras in the web interface. The SyncAPI can also be combined with the S3 Object Storage functionality to offload image storage to a cloud service.
The indi-allsky web interface is designed to be directly exposed to the Internet, if you have sufficient bandwidth on your home Internet connection. A simple, yet effective, access control system is implemented to let anonymous (or authenticated) users safely browse images and videos without exposing privileged controls. Only users with assigned administrative authority can make changes.
https://github.com/aaronwmorris/indi-allsky/wiki/Security-considerations
It is also possible to use cloud security offerings like Cloudflare Tunnel to further protect your indi-allsky site.
indi-allsky supports reading sensors natively on single board computers like Raspberry Pi.
https://github.com/aaronwmorris/indi-allsky/wiki/Sensors
Native dew heater support is built in for standard and PWM controlled dew heaters.
https://github.com/aaronwmorris/indi-allsky/wiki/Dew-Heater-Support
Native fan controller support is built in for standard and PWM controlled fans.
https://github.com/aaronwmorris/indi-allsky/wiki/Fan-Control
If you built your system with a focuser, it is now possible to control the focuser within the Focus view. 28BYJ-48 steppers are currently supported.
https://github.com/aaronwmorris/indi-allsky/wiki/Focuser-Device
indi-allsky supports being able to upload timlapse and star trail videos directly to YouTube
https://github.com/aaronwmorris/indi-allsky/wiki/Youtube-Uploads
You may choose to upload images and timelapse files to an S3 bucket. Once the images are in the bucket, images and videos in the web interface will be loaded directly from S3 instead of the local indi-allsky web server. You could easy host the web interface from your home internet connection and just have the large media files served from S3.
Currently, only Amazon Web Services is supported, but other providers could be easily be added. Just open an issue.
Estimated cost for an allsky camera holding 90 days of timelapses and 30 days of images on AWS (day and night): ~$2.00 (USD) per month (50GB of data + 180,000 requests)
AWS S3 and GCP Storage are currently supported.
Note: As of writing this, the AWS free tier for S3 supports 5GB and 2000 requests per month. In a single night, I achieved 80% of the requests limit (8 hours of images every 15 seconds is 1920 upload requests). The free tier is only sufficient for basic testing, but not long term usage.
GPS support is provided through indi_gpsd and GPSd integration. Any GPS hardware supported by GPSd will work.
JPEG and FITS Images exported [optional] by indi-allsky will be properly tagged with Geographic (latitude/longitude) and Astrometric (RA/dec) information in the headers. Tags include geographic location regardless of GPS support, but the information will be much more precise with the GPS module.
indi-allsky itself is written in python, but python is just the glue between the different libraries, most of which are C based which makes indi-allsky extremely fast. A 1920 x 1080 image can be dark frame calibrated, debayered, histogram processed, text applied, and compressed to a JPG in less than 0.5 seconds on Raspberry Pi 3 class hardware. PNG processing is a little more taxing, but usually only takes a few seconds.
ffmpeg video processing is considerably more expensive. A 2 minute 1920x1080 h.264 encoded video compiled from 3,000 frames requires ~20 minutes on Raspberry Pi 3 (4 core) hardware. Encoding takes place in a separate process from image aqcuisition and image processing and is run at the lowest CPU priority so image acquision is not impacted.
indi-allsky utilizes python's multiprocessing library to enable parallelizing tasks so that image processing does not interfere with image aquisition, etc.
All configuration is read from the database. Almost all of the configuration is managed via the web interface. You may use the config.py utility to manipulate the configuration from the command line.
3-4 weeks of constant runtime with no intervention are common. The only reason I restart my cameras are code updates (or power failures).
The hardware below has at least been plugged in and tested for correct detection and CFA decoding.

If you have an INDI supported camera from a vendor not listed, open an enhancement request and I can work with you to support the camera.
Common problems you might run into.
- The indi-allsky python processes consume ~500MB of RAM.
- 1K (1920x1080) h.264 encoding with ffmpeg requires an additional ~500MB of RAM. 1GB of RAM should be the bare minimum system memory. You should also have 100-500MB of additional swap space to prevent running out of memory during encoding. 2GB of RAM recommended.
- 4K (3840x2160) h.264 encoding requires an additional 2+GB of RAM. 4GB of RAM recommended.
- 8K resolution (ArduCam 64MP HawkEye) requires 8GB of RAM for full resolution video processing.
- In Raspberry Pi OS 10, the h.264 codec in ffmpeg has a maximum frame size of 4096×2304 (AVC level 5.1). If your camera generates higher resolution images, you will need to scale the video or use the Region of Interest (RoI) options to reduce the frame size.
- NEW: indi-allsky now has the ability to scale the native resolution images during the ffmpeg encoding phase, so you do not need to pre-scale your images.
- The RaspberryPi HQ camera has a bin1 image size of 4056x3040. Setting IMAGE_SCALE to 75 in the config results in a image size of 3042x2280. Alternatively, you can center crop the image using IMAGE_CROP_ROI set to [0, 368, 4056, 2672] for an image size of 4056×2304.
- ffmpeg in Raspberry Pi OS 11 enables AVC level 6.0+ which permits h.264 resolutions up to 8192×4320 (you must have sufficient system memory)
indi-allsky supports several file transfer methods.
