Description

This is my best image of Mercury (south up) captured this morning shortly after sunrise. The planet just clears a tree long enough to make a capture before the Sun gets too bright. I used my IR Pass 850nm filter, which helped greatly with the seeing. Nevertheless it is very challenging to image Mercury so low to the horizon (altitude 20 degrees), where one is looking through a lot of atmosphere. It is a testament to the lucky image process that such an image can be derived from the video capture, when you look at the turbulence washing over the planet on the computer screen. I took good advice from the Astronominsk guys on how to image Mercury and although this one is by far my best image of the inner planet, their images remain a benchmark for me. There seems to be a couple of large craters at upper right, which correspond to features on the WinJUPOS ephemerides graphic.

I have added a WinJUPOS graphic corresponding to the time of capture, along with a gaussian blur of this image to simulate the capture. Some of the major features correspond to my image.
