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.

Looking really cool. What resolution are your photos? I could try to put them as a skybox into emps.

most are around 3000x2000, I can go for higher resolutions by stitching multiple shots together like a panoramic though

another clear night last night (had some condensation/frost build up on the scope at some points though)
here is markarian's chain
taken with the camera i made, again
probably over 100 galaxies visible in this image (i cba to count though)

finally some clear skies again
here is m42, this is my first proper image with the camera i made a while ago
focus was a little bit off
