Should I clean my Corrector Plate?

[i Drew]

I notice there has been a little bit of buildup of dust and some water mark on my schmidt cassegrain corrector plate. It's been over a year now since I have own the telescope but I am anxious on cleaning it. I haven't notice any problem when i'm observing, it doesn't seem to be affecting the performance, but i'm thinking would it affect imaging?

If I should clean it, any advice on how to do it and what to use. Thanks!

There is loads of info on the net about how to clean a corrector - the coatings are very hard so its hard to damage but only do it if its really bad.

It really does not sound bad. I'm sure it is not messing with your views. I say leave it alone. If and when the time comes to clean it, just use some de-ionised wated. Failing that..................distilled (filtered) water.

SCT's are a bit like refractors. They dont need much upkeep on the optics.................unless they get really really bad.
