Hello! 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).

Before I start running my fully automated observatory from a remote location, it is useful to know what the weather conditions are like at the observatory site and an all sky camera is a great way of seeing what is going on in conjunction with my AAG CloudWatcher that 'measures' the weather conditions. Unfortunately, commercial all sky cameras have a pretty hefty price tag and I had a very limited budget for this project so I decided to make my own. The camera is the easy part and the excellent ZWO ASI 120mm was an obvious choice - it even comes with a 150° wide angle lens. However, the key to a reliable all sky camera is the enclosure it operates in. A camera and lens combination like the ZWO will work very well on its own for this purpose right up until the dew forms on the lens or even worse, it starts to rain so a waterproof enclosure with its own heating system is a prerequisite. Before I even started to think about the enclosure itself, I gave a lot of consideration to the heating aspect. The solution was sitting in my bits and pieces drawer - the components that I'd bought in a couple of years ago to make a dew-band for my 28mm camera lens when I wanted to capture a meteor shower! I never did make the dew-band but the Nichrome wire and pulse width modulation (PWM) power supply were perfect for this project. I calculated that I would need up 8 watts of heat for a 'de-frost' but a lower output for general use. With the heater resolved, I looked around for a suitable transparent dome for the enclosure and found a 100mm diameter dome for under £10.00 on Ebay. All I needed then was a suitable box to match the total width of the dome and again, Ebay came to the rescue. Awful skies mean that I have used it very little but I have enjoyed making time lapse videos of the night sky and I ended up buying a fisheye lens for the camera to give me a full 180° view. So here's the camera enclosure in all its glory Click here to view my first light timelapse video
I use an ASI120MC all sky camera to keep an eye on sky conditions when I'm sat inside the house - and to occasionally try to get some images of the Milky Way while the observatory is busy reeling off subs I used to just put the camera on the roof of the observatory but the cable hanging around was a pain - so I attached it to a plastic pole and then velcroed that pole to a wooden post in the ground Seems to be working really good so far :-)
Hi, I have a DMK21 with a CCTV f2 lens attached and I wanted to set it up like an 'All Sky' camera for meteor showers etc. It seems to work OK, but wondered what the best settings are? What capture software do you use? What are the best settings for exposure, gain etc? Thanks Daniel
