Hi All,
Taking my first couple of shots last night of the Horsehead, I ended up with this strange donut in the center of the image, you can see it on the neck of the horse.
My question is this: Could this be the reflection off Zeta Ori? Because this is one bright star. I took many other images of a different DSO and this donut was not there.
my scope is a SW 190 Mak-Newt and I am using a QHY8L.
(Disregard the large plane en route to Melbourne stuffing up this image.)
