work in progress, 1hr 30mins of IFN around M81 and M82 (same galaxies as previous image (this one http://i.imgur.com/xIMXatI.jpg))
ideally want to get 20+ hours on this, weather recently has been shite though

first outdoor test of asc
seems to work okay

now to drill some holes in the garage wall to mount it permanently

internals of the all sky camera, although without the camera itself
its controlled by a pi which is powered via poe

who built the case

its a HQ025EMSBK, made by RS but designed by Gainta
normally doesn't come with the dome, I cut a hole out for that and the sealed rj45 jack, then epoxied the dome into place
also epoxied some standoffs for mounting the pi and poe voltage regulator

just need to wait for my 10m long outdoor ethernet cable to arrive

Just to give some sort of scale to the precision required for these images, this is part of the guiding graph from tonights session. The blue line is error on the RA axis, the red is the DEC axis. RA has more error since this is the one that actually rotates to counter the rotation of the earth. You can see from the scale on the left that the maximum error is about 1 arcsecond. this is roughly 0.000278° which is just under 1 millionth of a full rotation. Since no amount of engineering is going to make gears precise enough for this without being huge and very expensive, I use a technique called guiding which uses a second small camera/telescope to watch stars and continously correct for error, which is what the screenshot is of.
