Condensation?

[Connor]

Random, newbie question but how bad is it in the long run for condensation to be on the lens of the scope and should I clean it immediately afterwards?

Dewing of the optics often happens when you bring the scope indoors. I leave mine capped and let the dew dissipate in it's own time. Don't be tempted to wipe the optics. Some folks feel leaving the optics uncapped while the dew clears is the way to go. Either way, let it go naturally and without wiping the lens / mirror.

It happens, nothing to worry about, even if it leaves blobs/streaks, they wont really effect the views you get. Optics have to get FILTHY before the views are degraded. Some people havent cleaned their mirrors/lenses in over 10 years and still get great views.

Just a quick one, what action should be taken against dust or small foreign objects? About the size of a fullstop .

Depends what they are really. Dust is nothing to worry about. Other small objects, hairs etc can be blown off with a bulb puffer.

Cleaning really is the last measure tbh, though if you really REALLY must, there are plenty of guides around on how to do it safely.

Nothing. They won't affect the image.

When i have condensation i actually leave mine uncapped and stand the scope up for about 15 minutes to let it go away by itself. It's always better to keep the scope in a colder environment to discourage condensation; not that it will harm the optics at all.

Thanks for the help.

Like the others have said, the condensation will not hurt lens or mirror surfaces but wiping them will as dust grains can end up scratching their surfaces.
