I'm afraid this will be yet another DIY all sky camera build! 😂 Hopefully interesting though... While developing my all sky software (shameless plug, see signature) one of the biggest problems is that I don't actually have a permanent all sky camera setup myself. I live in the middle of a big city with massive light pollution where the summer temperatures are just creeping up to 40C+, not ideal... So for a while I have been thinking about setting up a remote all sky camera to help with the testing of the AllSkEye app. Initially the idea was to mount it at a relatives house but then once I looked into what would be required to make it fully remote controllable I was thinking that if I go to all that trouble, I might as well look for a location with great weather and dark skies.
After a few inquiries I got a really great response from Jose at the E-Eye remote hosting facility in Spain. This was fantastic news because not only will the camera have nice weather and dark skies but the facility also has fibre broadband which is almost a must for what I have in mind further down the road (I am also planning to transfer some image data to cloud storage for archiving and further processing and that could potentially be a lot of data). So this is where it is going to go (all being well and my 3D printer not packing up!
I'll try to follow my progress here, maybe it will be helpful for someone. The basic idea is pretty simple:
Setup a completely autonomous and remotely controllable all sky camera Sounds easy enough... Well, let me tell you, it is not! To anyone having setup your own remotely hosted scope setup, my hat off to you, it's not an easy task! Initially I split this project into two parts:
The camera, lens, housing and everything that goes with it The control box that will control the above Unfortunately I don't have time just now to go into any details but will hopefully be able to do so soon. I just though if I don't start this thread soon I never will 😀. The state of play at the moment is that the control box is pretty complete and the camera housing is nearing completion (3D printer is very busy, not a fast manufacturing process unfortunately).
Here are a few pictures of what it looks like at the moment:
Allsky camera and weather station is very important parts of the modern observatory.
Here I wanna describe project that I build for my observatory.
I started a new topic because I believe that this project is unique and I hope this description may be useful because project is open source/open hardware.
This device contains two cameras, one is for beautiful daytime shots (over the horizon) and second for useful night shots. Also there is a lot of sensors: clouds, ir, light, temperature and humidity.
Heart of the device is Raspberry PI 2 microcomputer.
Everything is built in waterproof electrical box which can be found in hardware stores.
Yep this exterior is not very nice looking due to silicone sealant. But nice looking is not most important part, especially when mounting device somewhere on a roof
Acrylic dome is from CCTV camera.
Inside the box I glued a thermal insulation and copper foil which acts like a EMI shield. This foil is connected to the building grounding circuits.
All devices inside the box:
- Raspberry PI 2
- internal temperature/humidity sensor
- powering system (+3.3, +5, +12 volts)
- ethernet lightning protection
- tsl2561 ir/luminosity sensor
- mlx90614 cloud sensor
- cooling system
- rtc with a back-up baterry
External temperature/humidity sensor is mounted in separate aluminium can.
Cameras module is mounted on the bronze pcb stands and will be described below.
Raspberry PI runs all device software except database and long-time storage of the images.
Camera can be accessed through simple web interface which running on nginx server.
All data collecting and generation software is wrote on C, Python and Bash.
All processes is starting by the CRON.
Database is working on the remote server with reliable storage system and can be accessed through network. I'm using Mysql in this project.
I found that this solution is more reliable and convenient rather than local storage on the SD card.
All images are postprocessed by the software. Dark frames is extracted (only for night camera) and generated some text information on the bottom of the image.

I am sure I am missing a trick here but thought I would ask here anyway. I have the QHY5-II MONO and a meteor lens to use as a kind of allsky cam. However, I want to mount the CCD to a mount in the garden but do not want to collect the data with a laptop. Is there anything I can use to collect the data but a little mre mobile than a laptop?
Last year I developed an 'all sky' imaging application to run my Starlight Xpress Oculus camera (for Oculus owners you can find out more here: https://groups.yahoo.com/neo/groups/allskeye/info). I have recently added 'experimental' ASCOM support for it but don't have any other cameras to really test in on. If anyone is looking for this kind of software and would be happy to carry out some beta testing please let me know. Please bear in mind:
The software is really designed for traditional astronomical cameras using longer exposure lengths i.e. not video astronomy and am not sure how well it will work with faster CMOS cameras The software is mono only, no colour images can be processed (although it might be possible to use a colour camera to produce mono images - something I would like to test) It has been running for a while so is reasonably stable but please bear in mind that this will be a beta test so do expect problems! :-) Oh and sorry but it will only work on Windows computers from Vista onwards (no XP) Thanks,
