I have noticed that I am getting dust on my C11 in my dome.

It occurred to me that it should be possible to make a iris type cover, ( I don't have room for a flap type cover.)

Rather than re-inventing the wheel, I embarked on a google search, as one does.

I discovered this.

It looks as if it's just the job.

However I don't have the facilities to make one.

Does anybody know where I might be able to get one made?

or any other suggestions for a similar device.

Rick.

I just found the original paper

interesting...

Nothing to do with the seller, but If I had the room and a way of collecting it, I'd be bidding.

No idea of the backstory but I'm guessing it's sad.
