        Hi all,

        I've made an animation of Comet Lulin here: http://comethunter.lamost.org/secchi/CK07N030_HI1a.gif
        Hope u could like it! I'll try to do astrometry with Astrometrica (always led to negative star-matches whenever I was attempting to do astrometry with SECCHI images, strangely) or PIXY System 2 (once successfully!) of it probably this weekend once I'm free.

        Cheers, Wentao

        Gidday Wentao, You have Cardinal, lulin is moving very horizontal. Load images that are 4 or six hours apart and try to align the stars. Kind regards, Alan.

                    I have been having a good look for missing comet Boethin 85P as it is
                    currently meant to be in the HI1a FOV.

                    I am not expecting any thing and have not seen anything as yet,  8).

                    I have this (asteroid?) moving but cannot name it yet.
                     (40) Harmonia is long this line of y values so  I suspect this is it?

                    No not this, (40) Harmonia . I have updated the Starry night asteroid data from the Lowell.edu astorb.dat file. Many more asteroids are now being indicated.
