Thank you guys, now that i think about it more, you are all probably correct, although i do have a dew strap for the lens, i think what has happened is this.

The observatory is pretty warm and stays at about 8-9 degrees, and i did have the dew controller on prior to opening it up, but the outside air was only 2 degrees, this is why it probably fogged up badley on the first image run until it reached temp out side.

Thanks again.

Leon
