Thought a little update would be in order about my experience so far with this insulated mod to my Intes Mak.
Where I live, the backyard is lush with turf, a healthy vegie patch and a chook run. Add to this I live across the road from a park that is now irrigated. And just a couple of km from the beach. Dew forms here at the drop of a hat when the weather app's say the dew point hasn't been reached. I have heavy dew form on the underside of the tin awning of the veranda in the backyard.
I set up my Mak at 5pm, just before sunset. I put the insulating dew shield on at that time too. I came back out after the clouds had cleared a couple of hours later, and dew was settling on everything, except the optics. It was only by the time I was packing up at 10:30 that the corrector plate of the Mak started to form the softest coat of dew. I had a crystal clear three hours with the scope sketching the Moon, and the scope only yielded to the conditions well after I had finished. And by this time too, the dewshield had dew running off it too. If I had been pushing on into the night with the scope, I would only have needed a gentle application of a hairdryer to clear the soft dew on the corrector. For the location I live in, this is amazing!
I'm very happy with this simple and inexpensive mod.
Alex.
