So I bought a second had 500D and removed the IR filter using the excellent instructions from Gary Honis (Thanks Gary!). After an initial hiccup, where I'd not reconnected one of the cables, it seems to work ok, although I'm still waiting for a clear night to try it out in anger. However, when I give it a soak test of repeated 300 second exposures using APT, it dies and loses connection to the PC after a while. This seems to be related to the temperature of the sensor, which is reported in the filename by APT. It is all ok until the sensor reaches about 37-39o C, upon which the camera dies until it cools down. I have repeated this on three separate tests, so this is a consistent effect. Is this normal?
This is my first image with a Canon 500D, modified for astro. Seems to be a big improvement on my unmodded NikonD5300. I guess its not the best subject for increased sensitivity though. I think some of the tidal structures are showing? And this shows what else is present....
