Description: A beautiful sight in western sky. Venus is passing Pleiades. This was a good change to test my homemade travelscope (aka Talson). I used 32mm eyepiece which gives 25x and a huge 2ø field. With this magnification Venus is only a very bright ''star'' without clear phase...and Pleiades...check sketch out.
