Tried the startrail as a test of the K5 this evening. Set the camera on tripod bulb mode, left it with shutter open for an hour and three quarters. Is this picture what you would expect f 5.6 infinity focus. I did not do a dark frame as I have no idea how to do one and subtract it from the image. Any ideas considered!
It was a bit windy which is why the tree is not in focus, plus I did focus at infinty.
Have added a 100% crop of the original raw so you can check out the noise level.
