Hi James,
This is long winded, I know what I am trying to say.... see if you can follow otherwise give me a pm and I will send you my phone number and talk you through it.
If you go to this site below you can download the entire 509,000 extended minor planet list (can be very handy & up to date daily) for the Sky6 just ensure you have the latest Sky6 update installed - (ver 6.065)
http://www.minorplanetcenter.org/iau/MPCORB.html
There are 2 files
mpcorb.dat = 98 meg unzipped or mpcorb.gz = 24 meg zipped.
Once downloaded replace the old mpcorb.dat file under extended minor planets then run it. It will update positions for all minor planets.
You then simply do a search in The Sky6 for
MPL910 and centre it on The Sky6.
Otherwise you maybe able to just download Anneliesa by importing it directly into The Sky6 while connected to the net. In Data under Comets and Minor Planets choose the tab Minor Planets then you can either choose to manually put all the details in under ADD or go further down the list and choose BY NAME - type in Anneliesa and it should find it and you just add it to the list already in The Sky6 and so long as it has an X in the checkbox you should be able to search as above by name or by MPL910.
