Thought I would have a go and see what the 70D with 500mm lens could pick out last night while the sky was relatively clear of clouds. Venus was shining really brightly soon after Sunset but I had a job to make out even a couple of stars with the naked eye. Fortunately the camera was more sensitive.
Slightly cropped view of Venus with the Pleiades constellation (Seven Sisters) nearby
A slightly longer shot showed many more stars which I had no chance viewing with the naked eye
It may be better to click on the photos to see larger versions on my Flickr account.
