What guide camera are you using? I used to get that with a Lodestar which had a bad bright white line edge which I couldn't correct with CCDsoft but you can with Maxim (dark subtract).

Hot pixels are always possible but I got the spikes with both ST-I and Lodestar cameras. I use TSX and guider full image calibration which, hopefully, reduces the chance of HP. I do have ProTrack on so that might be a factor. When I get a clear night again (Ha!), I'll do some testing.
