Sattelite indeed Adrian. I was scratching for data so a pesky trail wasn't going to rule it out. In subsiquent image runs I will remove it from the stack as with big data sets i generally pick the eyes out and leave the data that has great FWHM (somewhere around 2.5-3) and no abberations!
I havn't seen you around for a while Adrian, how has things been?
