Here's my effort from this morning. Missed the ingress due to cloud cover but that mostly cleared in time for the egress. I couldn't fit the moon and venus in the same frame so tried some quick 2 panel mosaics.

180mm f15 skywatcher mak cassigrain at 2700mm. Canon 1100d 1/80sec at iso400 (2 single exposures stitched)

Great photo Rick.

Told all my work colleagues what to look of this morning (we had an 04:30 start). Cloud spoilt the view for the duration.

Your photo was all the further explanation needed.

Venus in phase really surprised them.

Cheers.

Thanks Derek, the cloud here was so thick here at 3.30am that you could not see any stars and I nearly went back to bed. There was a 25kmh wind blowing that cleared most of the cloud, (a couple of minutes after venus went behind the moon) so I had to wait another hour for the reappearance.



Thanks Michael, I've had a few go's at planetary/moon occultations now but clouds have thwarted all my attempts to capture an ingress stage. The long focal length of the mak would have been perfect for ingress but the dark limb of the moon was invisible at any exposure I tried. It was interesting visually to see venus appear from behind an invisible barrier. My 10" newt would have framed it better but it was far too windy for that sized tube. When Venus is on this side of the sun its phases do surprise a lot of people.
