VirtualDub quick intro

[The Thing]

I know what you mean Mark. My Jupiter footage with the QHY5 shows a near vertical artifact in some of the sets of frames I took. Its only across the planetary disc. Must be the same sort of thing. I am going to try a different version of the drivers from the astrosurf guys.

Duncan,

According to the July Astronomy Now article you referred me to, almost every camera has some kind of artifact.  Trying a different frame rate might (or might not) help.

The qhy5 software only allows an exposure and an delay to be set. The combination must result in a frame rate. I was using 25ms exposure and a 1ms delay. That would be approx 4 frames per second. I think I should increase the delay and maybe use the slow read option as every now and then the frame 'flares' bright or gets a bright band.

My maths tells me that's more like 40 fps, not 4.
