Summary

If you are tired of loosing your time seeing nothing with your Skymax 90 because of the dew, you probably should build a dew shield. An easy way to do that is to cut a piece from foam into a cheap fitness mat (200mm x 350mm), and make a pipe with scotch. That's all !

But I wanted to keep my dew shied mounted on the telescope, so I had to cover it from the dust, and I made a simple adaptor to put the original cover onto the dew shield :)
