My first attempt at a long exposure, hope this is the right forum for this. Have since discovered the myriad of ways to reduce all this thermal noise etc so I'll try another one, one day.
Not sure what the length of exposure was for this one, I'm sure someone could estimate it by the length of the trails (the summary says it was 1 sec which is clearly wrong!) I just put the camera out on a tripod and let it go on a full battery, the camera must have shut itself down when the power ran out. (and fortunately saved the photo) I'll get an external power supply one day.
Just got a new telescope delivered today - ED80 - can't wait to give it a go!
Nice shot, it looks like over an hour, probably closer to 2. What camera is it, the 350D? Not a lot of thermal noise for such a long exposure, doing well.

Wow, if I did that with the 300D the whole right side would be bright red! Great shot Cactus.
I'd say its probably getting closer to 2.5 to 3 hours. 15deg/hour and a quick rough measurement made it pretty close to half of the 90 deg angle from meridian to horizontal east.
