The lubricant is used where the primary mirror slides up and down the central column when you turn the focus knob.
Over time, it breaks down and drips onto the corrector plate.
It needs to be removed, replaced and the corrector plate cleaned.
If this is still under warranty, Celestron should replace it for free.
If it is out of warranty, I would still attempt to have it replaced by them (or repaired) as it is a known fault at manufacture.
Where did you buy it from?
Outside of sending it back to America, the only place I would consider asking to repair it would be Bintel.
However, I believe they may not be too keen because of the difficulty in the process. Neverthe less, I would use them as my first port of call if the original supplier cannot help.
Sorry, but I hope this helps a little.
At least you know you are not alone.

Hi Allan,
The scope would be well out of warranty now.......I brought it privately in near new condition about 5 years ago.
So its a job that cannot be undertaken at home then.......
Edit......... I just did a search on the web and it is very common......seems you can do a clean up yourself as long as you are very careful and mark everything to make sure everything going back in the same orientation........ might give it a go if I can't find anyone in Sydney to do it.
cheers
