Venus 2018

Postby Aratus » Sat Apr 21, 2018 10:56 pm

Venus is once again visible in the evening sky. At the moment it is actually on the far side of the sun, and very small. This isn't going to be a good appearance of Venus this year. As the planet gets nearer it will drop towards the horizon, and will roll about there from the summer onwards. It will make observation of Venus as it gets larger very challenging.
Here is the first photo of the season with Venus just 11 arcsecs across, and an almost full disk (91%)

I use an 11" Celestron SCT (CPC 1100) on an equatorial wedge, housed in a 2.2m Pulsar observatory. I use a ZWO ASI1600MC and Canon 500D for imaging.

Time to revisit Venus. However, even after 2 months it isn't much bigger than it was in April - still only 14 arcsecs across. 77% of the planet's disc is now illuminated. This photo was taken at 14:39UT, so at least the planet was nice and high. Unfortunately it will be dropping quite rapidly over the next few months.

Very nice.
We've recently been traveling through Spain and were able to entertain a French couple with that view of Venus one evening through our 127mm Mak.

Earlier in the week we'd delighted (and maybe inspired) a couple of Spanish children of about 7 and 5 with a view of Jupiter and some of its moons.

We'd hoped for better skies, but they've been disappointing overall.

On 6th July I took another photo of Venus. It was taken at 1504UT. ISO100 and 1/2000sec.
This is the same scale as the previous photos, so it can be seen that the apparent size of Venus has increased to 16 acrsecs across. The illumination is now 68%

I tried to see Mercury which at the moment is about as far from the sun in the sky as it gets, but sunlit haze drowned it out.
