Message: <blockquote data-quote="Binastro" data-source="post: 3499935" data-attributes="member: 111403">This morning I looked at Orion.The star images are really good over nearly the whole quite flat field.At the edge there is vignetting, but depending on position angle. At some positions quite a lot more than at others.In addition some edge stars are elongated but this seems to depend on the offset of the variprisms. At some positions stars are very good at the edge.I was pleased and surprised to see 4 Trapezium stars. Tiny points of light. This is fairly easy in 18x50, but it was just above 5 bulkhead light fittings each full moon brightness.In addition a new building 22 metres away has had a Rottweiler light on all night for a week. This is 20 to 40 times full moon, i.e. magnitude minus 16.5.I have stopped complaining as I consider planet Earth a  lost cause. My friend thinks there will be no humans here in 150 years, and I don't disagree with him.However, someone did complain as this morning the light was angled 45 degrees downwards.The Canon 10x42 L is very good but heavy and bulky. The IS worked well.</blockquote>
