Cleaning an SCT Corrector Plate?

[Swoop1]

I used my Celestron C6 SCT at an outreach event and last night discovered that some little darling has left a greasy paw print on the corrector plate.

Now, if this was my camera lens, I would have at it with some cleaning fluid and lens tissues BUT, i don't want to get banned from SGL for telescope maltreatment so, what advice for removing paw prints from correctors please.

Thanks,

Matt.

does it matter, unless its really bad you probably won't notice.

Cup of warm distilled water with a couple of drops of washing up liquid stirred in.  Good quality cotton wool balls.  Point the telescope slightly nose down, dip a cwb into the water and then drag it over the corrector surface, repeat until the marks have gone, new cwb each pass.  Finally swab off with new distilled water.     🙂

Did you have a dew shield fitted? I'm saying this because I have experience of a similar occurrence and I find a dew shield now stops small hands reaching the CP.
