Hot Pixel Problem
Hello,
I'm having trouble removing the effect of a hot pixel (producing a verticle line on image) from my Moravian G2-8300 camera.
Dark frame reduction ought to remove it but it doesn't entirely. I'm not sure what to do. I made a dark frame master composed of 10 seperate 4 min exposures at -20C by median combining. The light frames show the line but the dark fram only removes some of the line intensity. The single reduced frames show very slight streaking but of course when I try to combine the light frames trhe streak becomes more pronounced. Yes, the light frames and darks have the same time and temperature. I tried doing this in two different programs, CCDSoft, and SIPS (the imaging/capture) program made by Moravian. Both gave similar results.
Any advice much appreciated!!
Peter
