[g__day (Matthew)]

I guess their was either a leak or a bit of condensation - but when I balanced my scopes the other day I noticed about 50ml of (hopefully rainwater or condensation) inside my main SCT.

I tilted it on the mount so the lens pointed down and most of it eventually dribbled out thru the seam at the front of the OTA. I notice the mirror still has condensation on 50% of it and so does the main corrector plate - on the inside.

What is the best way to get rid of the remain water - just wait for a sunny day and take the rear eye piece off and let the sun slowly evapourate it? Blow it carefully with a hair dryer on the rear and front of the OTA?

Secondly - how to prevent this happen again?

Thirdly does it need a service (or how do you decide this) when this sort of thing happens?
