Had a look at the double transit of Io & Ganymede on Jupiter last night. This was around 8:45pm. Both shadows were clearly visible and was pleased to witness such an event considering the weather we have had the last few months. I did try to capture the event but the images I took were dreadful
However, I looked a the moon and noticed what appeared to be a straight line through a crater. I had never noticed this so again I tried to capture it and later did a little research and found I was looking at the "Straight wall" or Rupes Recta in the Mare Nubium region.
I did manage to get an image of this although it is out of focus and looked much better in the eyepiece.
Blog the previous nights viewing. Link to images on the gallery or simply describe what you observed the night before. Leave the technical and howto in another forum.
