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.
