Hi All, We have a image of white light the red end off the spectrum with a Meade DSI CCD which is very granny will darks, flats and bias sort it out, image enclosed shot of screen with a hand held camera not a screen shot.

Hi Peter, I don't think so as it looks like noise is the problem. You could try adding a number of captures to improve the S/N ratio. Using darks and flats always makes the S/N worse.
