rain spots on SCT front lens, how do I remove?

[DannyHarvey]

I have just got a few rain spots on the front of my C6 SCT what is the best way to clean it off?

The procedure for cleaning SCT corrector is same as cleaning normal lens

Step 1: Use an air blower to blow off as much dust as possible

Step 2: Spray of Baader on to a clean lens tissue or lens cloth, then wipe the spot

Good advice above, the baader wonderfluid and its microfibre cloth was the only thing that went on he corrector plate on my sct.

Ok thanks guys I'd better purchase some!

All of the water evaporated, and it left a few water marks, its too bad!

Danny, when you wipe your corrector, use minimal pressure and wipe from the secondary out towards the edge. Don't wipe in circles.

Good luck with the clean. I must get round to cleaning mine - I've got horrible dew marks on it!

[DannyHarvey]

I meant to say "its not too bad"! I may leave if for now. I'm going to find one of the proper cleaning cloths I have for my camera and use that when I get round to it.

I'm curious, why not circles?

If there is a gain of sand trapped between your cloth or tissue and the lens, wiping in a line will leave one scratch. You may notice the scratch before the next wipe and would stop, scream in horror, but that lens would still be usable.

If you wipe in a circle, that gain of sand will continue to scratch you lens, leaving multiple scratches and that would be end of the lens

[DannyHarvey]

Only just got round to sorting this out and buying some fluid - how bad am I?

Don't suppose there was much reason to rush, given the weather! :-/

[DannyHarvey]

hahaha!

Although you wouldn't want to scratch your corrector regardless of the method used, a straight scratch could introduce a spider diffraction effect whereas a curved or circular scratch would just cause an unnoticeable scatter.

I would wipe in straight lines but also with a rolling action so that you lift any potential particles from the surface as you wipe. I think I read something similar to this the other day on another thread that was sourced from Televue's website.
