Hello, the observation start time is stripped from the resulting stack so that Maxim DL can't do Astrometry on the image. Of course it makes sense as subs

OK, I spoke too soon. The strange coloured vignetting issue has returned. I'll post some sample files and maybe someone can have a look? Cheers Jonathan

Hi Ron, That's a very wide wide field for that comet. What lens did you use? -Eelko. ________________________________ From: ronw72

Hi Eelko: A suggestion to try to get rid of the star streaks. Split up the light sub frames into different group tabs but do it by every other sub or every

Hi Simon, Flats need to be in the whitebalance of your lights, white or gray is good, as long as the illumination of the frames is uniform and the histogram

on this point, do flats need to be white? when flats are taken of blue sky, does DSS convert them to white, or is the blue subtracted from the image? thx
