One very interesting and easy to locate constellation is Lyra, because it includes the fifth brightest star, Vega. In northern hemisphere Vega is the second brightest star with its 0.03 magnitude, and it is one of the three stars of the Summer Triangle. Lyra includes several double stars, which makes it an interesting target to observe. Additionally there are even two Messier objects, M57 and the Ring Nebula. Anyhow, I will not go into details in this article because the point in this article is to tell how Lyra can be located with binoculars.
In order to locate Lyra constellation, take your binoculars and look at the figure on left side. The figure is a screen shot from my Cartes du Ciel sky charts program, which is a free software tool for presenting star charts on a computer. The tool is configured based on my location, which is in Helsinki in Finland. If you are located in central Europe, United States or even on southern hemisphere, you need to take into account that sky looks different from your location. Anyhow, the first figure shows the location of Lyra, which is low in south when observing in Helsinki. Lyra constellation is located next to Cygnus constellation (left side) and Hercules constellation (right side).
When looking for Lyra, start by looking towards south first. Search for the brightest star close to horizon, which is Vega. As soon as you have found Vega, you should be able to locate the other stars of Lyra as well and you should see the formation of the constellation. For closer look at Vega, see the other two pictures of the constellation. Those figures are just zoomed to show better the Lyra constellation.
These three figures are star charts. In order to locate Lyra constellation, print out the charts, place them on top of your head in straight hands, and turn so that southern side of the figures is towards south. By this you should see the sky above drawn in the chart just like it is above your head. Below are more details for locating Vega.

2very sad and this website is not very helpful at all. It is to complicated to read, yet complicated all in the wrong ways. It doesn’t really tell people what they need to know about this topic.

3Hi Bob, I am sorry if I make mistakes with English. I am a Finn and I try my best with this blog, but every now and then I make mistakes with the language.
Bob, are you trying to find Lyra constellation or Vega star? Cannot find it? May I ask what is your location where you are observing? Please give me more details and I’ll try to help you. In afct, I would like to ask you what would you do different in this site?
Thank you for visiting and taking your time to write your comment.
