Thanks Bob Elliot !!!!!!!!1

I have the Microsky microfishe version of the POSS plates.
I have wondered about these "UFO" spots as Masaki calls
them. I thougt that was some plate defect or some bubble
from poor rinsing in photo -developing.

I now began with My1 + 2 =Polaris and there it is.
then at My26 with 1 Cephei and there was a thin blurr image
1 Cep. is 4.26 in mag.
Then I stopped looking for more I have seen earlier.

I am using 42 times magnifying on my screen it gives
Possplate=10mm >35mm on my screen
