Hello all,

I am having these weird visions of domes instead of craters when I
view the moon.
If I blink, or close my eye then look again everything is ok.

Does anyone know what the problem is? Is there a technique to
observing without getting into this "confused" state?

I have been viewing the moon for some time and this hasn't happened
before, although it does happen when viewing the photos of various
craters on VMA at times.

Regards, Frank Hunter.
