Description:
I get the light glow from three locations in the object, like a semi-circular
pinwheel of pairs, two SW diagonal to the two to N, NE. The gaseous background
is found in the upper areas of the cluster. I peruse IC 1805 (I think). I
really cannot distinguish one from the other.

I get the best sight in lower power (x76) and the UHC aids somewhat in
viewin the gaseous background.
