Hello, all.
New user, first post. I decided to not write anything about me in the proper thread because the reason I joined the forum, certain details about what I (plan to) do, and my question are tightly related to each other.
Bear with me, please. I work in a scientific facility that makes certain type of observations of the sky both at day and night time. However, clouds are no good to what we do, so we can only take our measurements when the portion of the sky we look at is reasonably clear. Although all the members of the staff live in the vicinities of the facility--and we are quite used to check weather forecasts and satellite imagery to judge the sky conditions--oftentimes it is tricky to decide whether it is worth going to the workplace. And worse, oftentimes we find ourselves waking up at ridiculous hours only to meet a cloudy (and useless) sky once we get there.
An obvious idea that comes up from time to time is installing a webcam pointing up the sky to check the weather conditions. Of course, day time is no challenge; even the cheapest webcam does the trick. My procedure consisted in taking shots every so often and making a time lapse with them. Although the individual quality of each frame isn't great, the time lapse video gives a very clear idea of what the clouds are doing.
But night time...is a different story. I heard of hardware hacks among the astrophotographers community that enabled certain webcams equipped with CCD sensors to take long exposures. Apparently, one can not buy them anymore. On the other side of the spectrum, I'm aware of especially built CCD cameras to mount on the back of telescopes, but that doesn't quite seem to be what I'm after.
Since what I'm ultimately planning to do is nothing more than a very particular type of digital photography, I thought somebody around here could give me some hints regarding the hardware needed.
Kind regards,
Jose
