My first successful attempt at recording surface variations on Mercury after many failures.

Small angular size and proximity to the sun made this a difficult observation and seeing was poor. Transparency was good. Little or no breeze helped as even a small movement of the telescope means that the planet disappears from the frame.

Did you manage to see or image the conjunction of Venus and Mercury on 2019.09.13? I saw it with a small reflector in France but was unable to image it although it was a pretty sight visually with the two planets very close.

I didn't get the chance to observe them on the 13th but they were still very close on the 14th when I made this observation. In fact, I used the much brighter Venus as a finder and focusing aid for Mercury as it was a very short hop away.

That's an excellent result, Chris, considering how difficult the conditions were and the small angular diameter of Mercury. Well done, and I look forward to seeing more of your observations.

Good job Chris imaging such a difficult planet. Venus being nearby is always godsend with Mercury though!
