Venus and Mars 2/25/2017

I was able to take these images of Venus and Mars Saturday night.  The goal was Venus with Mars being way past its last opposition of about 9 months ago and now only about 3 arc seconds across.Venus on the other hand is close to one arc minute across and will only get larger for a few weeks before passing under the Sun and entering the morning sky. Venus was shot with a red filter and even so each frame was a quarter of a millisecond.  It was the best 20% of 10,000 frames. Mars was best 20% of 5,000 frames with no filter and each frame was one millisecond. Last night Mars was about 6 magnitudes (or 225x) dimmer than Venus. Both were low in the west and seeing conditions were awful.  Also seen but not imaged was Uranus, which was pretty close to Mars.
