Looking forward to seeing how it goes for you, I've not seen any images using it yet. I have my eye on one as a replacement for my SW80ED-Pro with a view to getting more out of the shorter imaging times we get due to weather. I've been trying to justify the additional outlay to myself for a while but I've got a new job now so the financial side might be less of a concern, it's just the old problem of will I have enough time to actually use it whilst having a new job now LOL

I did put the tube + rings weight in my post (4.5kg) so looks like all the info is there on the FLO page now I wonder if this will help with my star halos on the ASI1600 on NB? It'll certainly increase my rate of data capture over the current SW80ED-Pro.

There is some info at the bottom of the page but no bare OTA weight. Tube weight with rings / dovetail / handle: 4.5kg (9lb 15oz) I was looking at a 6" F/4 Newt but this may have changed my thinking a bit now as closer to my current setup but with improved focal ratio.

I checked the all-sky and managed to capture it too! Quite low on the horizon on the camera saved images. AtlasVRocketLandSat9Reentry.mp4

I'm not sure you need it in C, python might work - though I must admit most of my coding is in C on microcontrollers so I've been stumbling around in Python to get it to work. Sounds like you just need a simple on/off thermostat style if you are just using relays with a bit of hysteresis. I used this as a starter to get the 18B20 reading in to the code, built upon that to get my MQTT values in too (they were already stored in files for use on the text overlay of the all-sky camera) https://www.circuitbasics.com/raspberry-pi-ds18b20-temperature-sensor-tutorial/ Just need a bit of math then to determine when to turn on your relay to suit your requirements (you might need an offset to take in to account the temperature difference inside the dome vrs the external dew point?) Here's a quick python code for a BME280 https://www.raspberrypi-spy.co.uk/2016/07/using-bme280-i2c-temperature-pressure-sensor-in-python/ Looks like https://www.waveshare.com/wiki/RPi_Relay_Board has some python code examples to control the board. There's lots of thermostat examples but they seem part of a complicated heating control rather than a simple turn on relay if measured temp < demand

I use something similar, it's a MOSFET which is controlled PWM from the PI and switches a ni-chrome wire based heater I have in the camera mount on the dome. I then have a 18B20 temp sensor touching the heater element so I can control the temperature it is working at. This is then used in conjunction with the dew point of my weather station to workout what the dome target temperature should be (it's a simple offset at the moment). A python script then uses a PID control look to manage the PWM to the MOSFET to track the desired target temperature on the heater. I'm using this shield which I have a couple of for another project (another dew heater as it happens!) https://www.tindie.com/products/mostlyrobots/4-channel-mosfet-shield-for-wemos-d1-mini-esp8266/#:~:text=the cha...-,The Four Channel MOSFET Shield for Wemos D1 Mini contains,up to a potential 20A. The python code is a bit rough and ready, it's not something I have programmed in but managed to hack together something based on examples else where. My weather station uses MQTT to communicate stuff, and I already had some data being captured by the PI for the overlay on the all-sky so it was trivial to add to that the dew point data and then bring that in to the python script. The ni-chrome wire is out of an old toaster, looped round within a 3d printed part. Messy proof of concept... Slightly less messy final install... Current position awaiting focus check before I put it on top of a scaffold pole where the weather station is...

Yeah - I had similar issues, mostly computer says no - it's quite different to when I was last looking for a job! 21 years with the same company in consultancy, redundancy and then the pandemic put my job hunting on hold and I did a 90 degrees shift to teach people how to cycle, most rewarding job I've had, but it doesn't pay the bills so I suspect I'll have to get a "proper" job at some point. Anyway, back to the all-sky... I noticed the version history is't up to date after install of the latest - I checked the git hub and the version text isn't aligned with the current version (it only goes up to 1.2.4) - no big problem but thought I'd let you know I've made some progress of late whilst I've been sitting around recovering from an operation. I've not got a sky temperature on my weather station with a view to cloud detection and thought it would be good to get it on to the all-sky so I could compare temperatures with the view. Works well so far, data arrives by MQTT to the all-sky and then I add it on to the banner text so I can then review the movie to see the temp vrs view. I have contemplated putting some sort of grid overlay on so I can try and calibrate the view to temperature and then use the numbers to map to cloud cover. Not progressed that much as I keep jumping from project to project LOL - dew heater for the all-sky is the next on the list! Shame it was a full moon last night, such clear skies!

Worth looking at PLA+ (it's like a mix of PLA and PTEG) but prints as easy as PLA material colour certainly has an effect as does the loading on the final print (all the deformations in this thread appear to be due to the pulling load of the belt tension). I've had PLA lose tolerance overtime by shrinking (car phone holder so was always in teh sun and heat) - I guess it's just another consideration we need to put into our 3d printing designs I find PTEG tricky to be consistent on printing however I don't have the same issue with ABS which is supposed to be more tricky to get consistent!

OK - just checked with a Photometric color calibration and my redownloaded DR10 worked fine

Hmmm - I did months ago, just tried again now and no problems here? when you say fail what do you mean, size OK but doesn't work in PI ? (I haven't rechecked that yet)

This has some promise but I suspect to earn the 30 euros I'd have to see that it can be run as a daemon and some sort of web front end, I might give the free version a test ride.. I wonder if it can be combined into @Mognet excellent front end all-sky camera?

Yep - that's got it, found about 4 empty directories (I think I was using find but only reporting files initially rather than files & directories...) index page back to normal now, will see how the file space goes when I get close to the 2GB mark again. I found out why I wasn't updating, each time I wget the file I hadn't removed the old zip file so it was just downloading a main(1) ... main(2) etc and then when I unzipped I was just unzipping the oldest file called main.zip rather than the new download. Might be worth adding a step to the update instructions to make sure there isn't an already existing main.zip before wget'ing the next one. Anyway I am now on v1.2.4 Good luck on the job hunting...

Think I might have spotted an issue or 2? Looks like the new about.html doesn't get copied as part of the update? Fixed with a reboot! I also note "no crontab for root" which might be why the file clearup isn't happening? Y/N is case sensitive so needs a lower case 'y' to work My missing directory issue is still there though, so the actual about link is lost at the moment (see above post for image)

Yep - I think mine hasn't actually updated based on that! I've managed to break the main page, the SD ran out of space so I did a "sudo find /var/www/html/history/ -mindepth 1 -mtime +42 -delete" which now means it reports a missing directory and no about link is there anymore.. I'll give the update another go

Finally got round to updating, very easy to do... the SD had ran out of space which prompted me to ssh on and do something! Did you add a version number to the about page, seems to be missing on my updated version, just wondering if it got missed on the update?

It's raining Sunday so I'll give it a go then I think - thanks!

Is there an easy guide to upgrading from the GIT without having to reenter long/lat etc?

Will do. In between the rain here we had a bit of clear sky so managed to see some stars! Focus not as bad as I was expecting, so I think I will leave that alone! I seem to recall it being a bit of a pain with such a fine threaded small lens! I think there must be more heat kicked off the 3B+ as there is no sign of condensation like there was before, but perhaps the more exposed location is allowing more air over the dome too which helps.

I forgot to mention, you might want to add a link to your git and perhaps a version number or similar somewhere (on about perhaps? ) Other than that, it seems more stable and responsive that previous incarnations - a great evolution of Pete's all-sky camera! Well done. I've not delved in to the scripts yet to see where to add my MQTT data so might take a look at that if I get some time this week.

Well the hardware watchdog works great, so much so I've moved location to sort of where I always intended it to be, at the bottom of the garden - though at the moment it's sat on a wood perch I've laid onto the shed roof - hopefully it wont get blown over! Mine runs off a static DHCP address so always gets the same IP no mater which access point it's on. I need to ssh on to it and see what the signal strength is for it as when I was up the ladder the AP it is associated with was quite weak on my phone but the main AP was better - of course how that plays out inside the ally case of the camera enclosure is what I need to check - though so far it seems fine when streaming the video from it. Location seems better (which I expected) with more sky visible now - though I might need to refocus at some point when it is drier though it now requires a ladder rather than just some steps to get to it!

Seems to be going well so far, though I have noticed that whilst I have an entry for last night and yesterday, the night archive is just one image, but the latest night is the actual full set of files/video. Perhaps the creation of the archive needs to move to when the start of the next night collection starts? Also, I had a router issue today which resulted in the house network being effected and I had to power cycle the all-sky to get it back on - not associated with your code of course, but a common issue we all might encounter especially if the camera is up high or bottom of the garden etc... Anyway, I've just come across a hardware watchdog on the Pi which I haven't tried, but looks promising - I wasn't really wanting to restart the whole device though, just a wifi connection watchdog, but the hardware one might be worthy of consideration - I'll look in to it further. Details here: https://diode.io/raspberry pi/running-forever-with-the-raspberry-pi-hardware-watchdog-20202/

Success, painless install too! Just need to integrate my MQTT weather station data and we are back to all-sky land (might need to refocus the camera I think!) I ended up sticking a spare 3b+ in there, tight fit with some knife skills on the USB lead, not sure if I can fit a POE hat and Ethernet cable in to the current dome, may need to print a custom enclosure, which wasn't really in the plan... Same camera, different ribbon cable, but there was no visible indication of why the camera had stopped being recognised by the zero. Same SD card too, so I suspect either the zero or the cable to be the issue...

pi@allsky:~ $ vcgencmd get_camera supported=1 detected=0 Thanks for that - it's been so long since I played with it I forgot most of the diagnostics stuff... Looks like I will have to get the ladder out after all ! LOL

Hmmm I'm getting [quote]Welcome to the setup stage of Mognet's All Sky Camera ===================================================== Please connect the camera before installing Install cancelled pi@allsky:~/Mognet-All-Sky-Camera-install-main $[/quote] This could coincide with my read-error I am getting on the original all-sky or could be I haven't disabled the original all sky yet! ** EDIT ** Right, the /usr/bin/raspistill -q 100 -ISO auto -awb greyworld -n -ex auto -w 800 -h 600 -o /run/shm/webcam.jpg command is also returning "mmal: Camera is not detected. Please check carefully the camera module is installed correctly" So looks like I'll need to get the ladders out and remove the unit to inside to look at whats going on! Hmmmmm

Right - thanks for this, I think I know what I'll be tinkering with when the rain stops this week!
