Mercury and Venus – May 22, 2020

This slideshow requires JavaScript.

Friday was another day when, because we didn’t get the predicted rain, I was able to enjoy some astrophotography: in this case, a conjunction of Venus and Mercury.  (A conjunction is when two objects appear near each other in the sky.)  Note that, even in the picture, you can see that Venus is a crescent.  Like the Moon, Venus has phases, depending upon how much of its sunlit side we can see.  In fact, it is even more of a crescent than it looks in the picture – only about 5.3% illuminated – as you can see in this neat animation.  If you zoom in, you can see that Mercury is also not a circle – it is 67% illuminated.  The two are different because they’re in different parts of their orbits relative to the Earth.  Venus is close to passing between the Earth and the Sun, so we see very little of its sunlit side.  The lines between Mercury and the Sun and the Earth and the Sun are almost perpendicular, so we see a much larger percentage of its sunlit side.

I have rarely seen Mercury, so this was a real treat.  It’ll be visible for a few more weeks in the evening sky, so if the clouds stay away, I’ll have another look.

MoonAndVenus 20200424

Ever since planting my virus victory veggie garden earlier this month, I have become like a farmer, obsessed with the rain.  The forecasters keep saying the rain is coming, and then it doesn’t.  The upside of that is: clear skies for astrophotography!

On April 13, I tried to capture a picture of Comet C/2019 Y4  (Atlas), but no joy.  It was falling apart and too dim to find from my suburban driveway.

Last night, the Moon and Venus made a lovely combo at sunset.  Even with the 300 mm lens on the camera, Venus looks like a bright blob – not circular, but not with any shape.  In my husband’s 15×50 Image Stabilized binoculars, it looked the same as with the camera.  However, with my 8-inch telescope, it was a beautiful crescent (although much fatter than the moon).  It was an interesting demonstration of the benefit of a bigger aperture.

I thought the new Moon setting into the trees was also a lovely sight.

Dell City Astrophotography April 2019

Last weekend we took a break and visited Dell City, Texas, where we stayed in a lovely B&B, enjoyed gorgeous sunsets and sunrises over the Guadalupe and Cornudas Mountains, and enjoyed seeing the stars and planets.

As the song goes (sing it with me, y’all):

The stars at night

Are big and bright

Deep in the heart of Texas!

It is true!

And I had great fun trying to get some good pictures of the beautiful sky full of stars.  But just like folks buying new telescopes need to be reminded that they won’t get the views that they see in the published pictures from the Hubble Space Telescope, I had to learn that the view from a telephoto lens isn’t the same as the view from an 8-inch telescope.  So the Messier objects, which are nice objects to find in my 8 inch telescope, are mostly fuzz balls with my telephoto lens, even with a sky-tracking camera mount and the ability to take a long picture.

The other thing I had to deal with was an embarrassment of riches – there were so many stars that it was hard to make out the constellations.

I started the evening of April 27 trying to find the two brightest available comets, but they were really too dim to be seen.  I did get familiar with the constellation Leo, and saw a beautiful meteor pass through it – it’s even in my picture, though it’s very faint and you have to zoom in.

I turned from there to finding Messier objects, and found M13 in Hercules, M4 in Scorpio, and M80 in Scorpio.  Fuzzballs all.

Here’s a closeup of M4 with the blinking lights of an airplane.  (M4 is the fuzzy one.)

Finally, I waited until Jupiter rose to get a picture of it with its line of moons.

The next evening it was cloudy, so we got up early the following morning for a last view of the stars.  It was totally worth it – we got a lovely view of Sagittarius between Jupiter and Saturn and the Milky Way just before dawn.

Moon and Venus

MoonAndVenus20180615

Last night, as we exited the movie theater, we saw a beautiful conjunction of the Moon and Venus, with a bright Venus floating above a crescent moon.  The cell phone pictures did not do it justice, nor did my hastily set up picture shot from the car window.

MoonAndVenus20180616

So I prepared to take pictures tonight.  The Moon had moved!  Still a beautiful conjunction, yes?

And since I had the tripod set up, I captured a picture of the Moon as well.  It would be fun to explore its cratered surface.
