I took the image with a Meade 10 inch Schmidt-Cassegrain telescope
ZWO 120 MC-S camera with 3x Barlow lens attached.
I've added a bit of magic with Photoshop to the second image to show a Sun flare :-)
As Venus starts to get larger in size it also shows a smaller phase this is because we are seeing the planet come toward us in its orbit around the Sun. When it’s at a crescent phase it will be at its brightest because its getting closer the Sun it will also look its largest to us here on Earth through our telescopes because it will be close to us in its orbit.

Galileo's Observations of the Moon, Jupiter, Venus and the Sun

Galileo Galilei's observations that Venus appeared in phases -- similar to those of Earth's Moon -- in our sky was evidence that Venus orbited the sun and contributed to the downfall of the centuries-old belief that the sun and planets revolved around Earth. Also sketched here are Jupiter, Saturn and Mars.
