Canine constellation

Canes Venatici is a somewhat vague constellation and may not be easy to find.

The constellation Canis, located on both sides of Capricorn, is located in a slightly barren area in the night sky. For at least hundreds of years,

Canis Canis is considered as a pet in Mu Fu, but this constellation may not be "isolated" before the end of 17.

At that time, Jahani Hevelius named the two tengu Astri Weng and Zara (maybe he named them.

This constellation is separate from their "main" constellation.

Perhaps the most impressive star in Canis is Star Y, also known as La Superba.

Variable stars with brightness ranging from 4.7 to 6.2. The dimming period is 158 days.

What is more attractive to the observer is its bright colors. It is located in the night sky, about 700 light years away from us.

One of the brightest carbon stars can also show striking red in the smallest optical equipment.

Although it is unusual to find an open cluster so far away from the plane of the silver plate, it is so in Canis major.

There is an open cluster-Upgren1(right ascension 12: 35, right ascension +36 degrees 17). Phil Harrington.

In the book "Around the Universe through Binoculars", we will

Our attention was drawn to a bright cluster of about ten stars, which is located in the southwest of Alpha Canis.

Upgren 1 is only 380 light years away and is one of the oldest known star clusters.

In the past 3 billion years, the number of stars in Upgren 1 has gradually shrunk to its present state-surplus.

They were all abandoned in the long years. Upgren 1 is 1965, which was first taken by Rubin and Upgren.

Canis Canis also has a globular cluster.

It's certainly not bad (well, maybe it's quite spectacular for M3), but it's true.

The flash lies in deep space objects outside the river. There are at least 367 quasars (but the brightest) in the constellation Canis.

A dwarf galaxy was discovered in 2000, which is strikingly similar to "our" large magellanic cloud.

The child is like an irregular rectangle. Among them, the star cluster is quite young, because astronomers think that galaxies are rod-shaped.

Many stars found in this structure are less than 5 million years old.

In the DSS picture, just next to the north vertex of the galaxy, you will notice a well-defined hook.

Like a galaxy, it is quite spectacular in a big telescope.

With a larger mirror, you can even see the companion galaxy in the DSS picture.

There is some controversy. I have heard some sayings that this is just an illusion caused by photography, but this is not true.

It exists, but for me, it is really eye-catching. I was once in a mirror as small as 4 inches.

I've seen traces of the Star Bridge. This requires excellent conditions, but this is exactly what I do at this time of year.

Almost every observation will pay attention to one of the celestial bodies.

I saw traces of the structure of the rotating arm in a mirror as small as 4 ",but in a telescope smaller than 8- 10".

There's really nothing attractive about it. I clearly remember a very transparent night in my old house.

In the 10 "mirror, the rotating arm is easy to see. 15 "or 18" mirrors can be displayed under almost any conditions.

Rotating arm structure. Recently, in the dark night sky, I was lucky enough to observe it through a 25 "mirror. I saw far when I was 25 years old.

From the left and right binoculars, the target is indeed a bit like a long-exposure photo. Specifically,

A lot.

I also found that (like other celestial bodies), the detection of details such as visual spiral arms depends on observation.

Conditions and observation experience-don't give up hope if you observe it for the first time, the second time or even the twelfth time.

I can't see the details when I rotate the galaxy. Put it on the target list and come back from time to time-

There's a lot of fun here.-a lot of fun.

However, don't think you need a big telescope to find M5 1-not at all. I used to.

It has been seen in many binoculars and small telescopes of different sizes (less than 4 ").
