In case you missed the Venus-Moon close encounter

Last Saturday evening, if you happened to look outside and had a clear view there is no way you could miss the Venus-Moon close encounter in the dark blue sky. But just in case it was cloudy, or you weren’t paying attention here it is.

For those curious on the camera setting, the above is cropped from a single frame at 33mm f/4.5 1/30sec and ISO800 with Canon 80D.

Moving up to 85mm gives you the image below, also at 1/30sec and ISO800.  Both images were hand-held from a bedroom window. Could a tripod have helped? Sure, but I figured I could do just fine , especially with image stabilization enabled on the lens.

To put a bit of perspective on the distance of these two heavenly bodies and their apparent size in the sky I’ve added a bit of information on the above image. While Venus may be nearly 4 times larger in diameter, it looks quite small next to the Moon in the sky.

Moon and Jupiter Through the Clouds

After yesterday’s photo with the smart phone, I decided to go for a more professional shot and grabbed the Canon 80D and capture once again the Moon and Jupiter through the clouds. However this time around took two exposures, and stitched the together.

The wide-angle was 24mm F4.0 1/10s ISO-1600. This was to pick up the clouds against a night sky as well as Jupiter. Then a close-up of the Moon, with a shorter exposure and lowered ISO to pick up details of the lunar surface (85mm F5.6 1/250s ISO-200).

Opened them both in GIMP and played with layers, masks and curves to get the desired image.  The close-up Moon photo was scaled down to match the 24mm wide-angle photo to avoid having gigantic moon.

 

Bright Jupiter

Sometimes all it takes is a little cloud layer to hide the background stars to really reveal how bright Jupiter is right now. The photo below was taken with my smartphone on May 26th, with Jupiter clearly visible next to the Moon.

Jupiter and Earth were at their closest (opposition) on May 8th, but the entire month of May is a good time to spot Jupiter as it’s up high in the sky most of the night. Once Venus sets in the early evening, Jupiter is the brightest “star” in the sky, a good 20 times brighter than the next brightest stars.

Up until May 28th, Jupiter and the Moon will be near each other in the night sky, making for good photo opportunity.

Moon and Venus on May 17th

Came home from my piano lesson (yes you can still learn a new instrument past 40) and the sight of a 2-day old Moon and Venus in the dusk sky was stunning. Unfortunately by the time I got home to grab the camera, the sky had darken quite a bit, so I lost my opportunity for some color in the photo.

While I did take more close-up photos, I find adding the rooftop in the foreground helps establish scale.

Notice the Earthshine, it was easily picked up to naked eye.

Constellations at the Zenith

We don’t often look “straight up”. Unless you are laying down, it’s not a comfortable viewing position. However there is lots to see and the Big Dipper (Ursa Major) is right overhead this time of year.

Setting up a camera with a 10 second exposure can capture quite a good deal of the sky, and you don’t have to worry too much about star trails. What stands out is the large variations in the colors of stars, from cooler deep reds, to hot bright blues.

M44 Beehive Cluster

Image

In one of my previous post I mentioned how Messier 44, the Beehive Cluster, would be an easy find the evening of April 22-23, so even if I took this photo on the 21st, the same evening that I took a photo of the Moon, all I needed was to moved a few degrees north after observing the Mooon to image this large open cluster.

Photos of open clusters with small refractors always lack the diffraction spikes that really make the stars stand out.  So a little photo editing did the trick to spice up the image.

Never Wait for a Full Moon

The Moon should be the first thing you look at the day you get to peer through a telescope. It should also be the first thing you photograph.  However don’t wait for a Full Moon.  Sure a large round moon over the horizon can be breathtaking, but most of the subtle details of the lunar surface disappear under a Full Moon.  The lack of shadows blends away the peaks and valleys, crevasses and ridges. It is really this dance of light and shadows that makes the craters stand out.
