Facebook reminded me that almost three years ago I posted a crescent Venus. Coincidentally (or may be not so much, given the climate and periodicity of Venus as evening star), I had another shot of Venus compiled last week. And here we go:
While going through my shots, I realised that I have an interesting ensemble of Venus photos over 3 years:

While going through my shots, I realised that I have an interesting ensemble of Venus photos over 3 years:
 6 Dec 2013 |
 26 Jan 2014 |
 25th Nov 2015 |
6th Dec 2016 |
Obviously the images aren't to scale. The 2014 image is a 2x enlargement after 2x barlow and 640x320 crop while the 2015 one is very likely to be shot without a barlow.
Regardless, I am quite happy to stumble across these as it shows a clear phase change of Venus around the same time of the year. In 2013, it starts off with a crescent phase with 205 moving in to a half full. In 2016, it is in a waxing gibbous state.
In 1610s, Galileo was the first in recorded history to observe that Venus has phases just like the Moon. There have been numerous sightings and confirmations of this after that, and I am happy to be one in thousands who managed to observe this.
Nice job with the Nexstar4SE
