Venus in the Pleiades

Tonight and tomorrow night Venus will be passing through the Pleiades star cluster (also known as Messier 45 or M45) as seen from Earth. the planet isn't really passing "through" the cluster but just positionally appears to be passing the cluster as seen from our planet. A 400mm lens and a full frame digital camera were used to image the conjunction.

Below is an image shot through a Celestron C5 with a 0.63X focal reducer using a Canon EOS 1D Mark IV. Note the peculiar internal reflections. Sigh.

I would like to explain to me the reason that the date of 04.03.2012 in the first photo.

Does this first image refers to a probable composition of the conjunction, the date of 04.04.2012?

Excuse me for my previous comment. Also I did not realize immediately that it was a typo. 03.04.2012 instead of 04.03.2012.

thank you

thanks Roberto - actually it wasn't a typo - one image uses the American dating notation (mm.dd.yyyy) the other uses the European notation ( That's my story - I'm stickin' to it. :-)
