Hi Everyone,

I really want to protect my telescope (130mm F6 APO Triplet Refractor) and equipment as best as posibble so just wondering what others do when they pack up their equipment on the very dewy nights? When I image for a few hours on these nights, the OTA is covered with some dew but the lens is still clear as it is protected by the dew shield. When I pull the equipment down I place the metal dust cap on the telescope and take it inside and I am concerned that there is condensation forming on the lens underneath the dust cap. I am guessing that the felt lining in the dew shield retains some moisture from the night so is this a possibilty? As you can imagine, when the scope comes in from outside (say 8°C) to inside (16°C) a little more condensation occurs on the OTA which I just wipe off with a cloth. That isn't a worry, it is the lens which is my primary concern.
Any thoughts appreciated.
Regards,
Lucas
