OK, Patrick, this is REAL dumb, but I thought focus didn't matter with a flat field. So why does it? And Deb: I guess I passed along some bad info to you. Sorry. -- Joe
Flats contain data (it's just kind of hard to see) and all of those data need to be in the same place as the corresponding data from the white light image. Changing focus changes the location of the data. There's more detail in the on line Bisque manuals. I'm flying off to Wendover in a few minutes to check on a site for January's Stardust Watch but after I get home tonight I'll try and find the URL and forward it to you. Blue skies! Patrick
