It's an internal or possibly external reflection of venus.lsintampa wrote: ↑Thu Jan 16, 2020 5:53 pm I have upgraded camera arriving tomorrow - if the weather permits, I'll be trying some new shots - taking into account the tips provided here.
Meanwhile, I had a total flop last night - all my bad - but this picture was taken with my D50, wide open, for 2 seconds of Venus. It's not a "good" shot, taken with a poor camera, but I'm curious what the blue spot is?

I've drawn two diagonals to mark the centre. Note that the reflection is diametrically opposed to Venus, exactly where a reflection should be.
Did you have a UV or skylight "protection" filter on the lens? The cheaper versions of these filters frequently produce these type of reflections because they don't have the same coatings as camera lenses.
If so, try it with the filter off.
