Gamma Cygni - Sadr and associated nebulosity (c)Duncan Evenden 2011
Your outside, your telescope is tracking a nice object and you are enjoying the view. The sky is completely clear, you can't believe your luck after so many days of cloud. It's getting colder.
What's happening, your lovely sharp bright object is becoming fainter and a blurry. You check the sky, not a cloud in sight. Then you check the front of your scope. It's completely fogged up. You need a dew heater.
A quick search tells you you need to spend a lot of money - but whats this, you can make your own! However you don't know where to begin to get the bits and bobs you need in the quantities you will need.
So why not just buy a Dew It Yourself kit? Save yourself a lot of hassle AND money - and ensure you have uninterrupted observing and imaging.
