Comet ISON October 6th 2013

I don't know why, but I cannot seem to dig out comet ISON properly. After several attempt, this is the best I could do. I guess some of the problem can be attributed to the fact that my mount isn't following the comet. Rather it is following th stars. And thus the comet smears out over time. I tried manually stacking it. But even that failed. So I guess I will just have to wait for it to swing by the Sun. Hoping it won't just vaporize and disappear. We'll see what happens.
Technical details : Pentax K5, ISO800, 35x30 seconds. Teleskop-Service 80mm F/6 APO w/ William Optics field flattener. Celestron Advanced VX mount. Partly stacked by DSS, manual stacking and processing in PS.
