After 3 weeks of cloudy nights, I am finally imaging Tmz85, but it is very faint - not visible on the 16 second images which have a limit of mag. ~16 - 17. I will have to stack at least 4 frames to do photometry on anything at all. ===== Regards, Lew Try Lew's instant automatic observation plotter.
