Christophe - Wow! Excellent Shots! Mercury is almost like looking at Venus!


Lately, you have done such a great job imaging the planets. Before, I was hoping that you would imaging Mercury too. This is the best week to take more good shots while Mercury is displaying from half to gibbous. At this phase, Mercury exposes much of the disk while it is still relatively large and quite bright at -0.5 to -1.0 magnitude! I wish everyone here will spend sometime observing Mercury visually and make a drawing as best as possible!


The weather sounds good for New York tomorrow (Tuesday Sept. 30th) so I will be planning to image Mercury around 14:00 UT to 15:30 UT. Around that time, it will be close to the local meridian approximately 55 degrees above the southern horizon. Lets see what will happen!


I will take a closer look at your images when this apparition is over. Please, keep it up!

Dear all -


This morning, I had an excellent view of Mercury. (I mean excellent!). I imaged it under a nearly perfect seeing condition.


I used a Wr. #25 red filter to cut the blue light against the background. Mercury was taken in broad daylight just half an hour before the local meridian at nearly 55 degrees above the southern horizon. Just beautiful! Mercury was showing a slight darkening just south of equator. They are well known features Solitudos Martis and Jovis. I have combined two images at 0.02 sec. exposure at f/25 to produce this image.


I hope some of you will have a chance to view Mercury during this excellent morning apparition.
