   Hello.
   
   I am experiencing a repeating pattern of horizontal Dashed lines in Darks and BIAS frames. Could you please advise on a possible cause? I have uploaded a file for reference. Thanks.

   Mystery solved. tracked down the problem to Nebulosity. When using SGP or CCDOps, no horizontal dash lines.

   Frame looks fine... guessing you need a software or video driver update.
