Dew

[dmn21]

So, this probably sounds a bit stupid, but I managed to get the 'scope out in between the clouds tonight and after a while things started getting dimmer and dimmer. So I'm there trying to point it at stuff away from the clouds and twiddling the focus knob, all to no avail. It's then I notice that the eye pieces and secondary mirror have all fogged up.

Being a newbie, I'm reluctant to do any wiping of surfaces so I just brought the kit in and called it a night. I've seen a ton of anti-dew kit in the shops but what's really needed and what works?

Thanks!

I would make a dew shield. I made one out of neoprene and velcro. It works really well, and stops the secondary fogging up on my newt..

Ah, great thanks! There's always a thread which has already discussed something :-)
