Yes I saw it without the binoculars. I couldn't see anything with them.
You could clearly see the long round bit in the middle and the solar panels outstretched on either side. Not saying you could read the writing but you could clearly make out which part was which.
Even my old folks could see it without their glasses !!!.
I saw it about 3 times in the one night, and again the next night. Each time the sky was completely clear with no clouds at all.
