How to find Andromeda?

Here’s the technique most people use to find the Andromeda galaxy. Just be sure you’re looking in a dark sky. Look northward for the M- or W-sha ped constellation Cassiopeia the Queen. Now locate the star Schedar in Cassiopeia. It’s the constellation’s brightest star, and it points to the Andromeda galaxy.

What is the most important thing you need to see the galaxy?

Just be aware – bright moonlight or city lights can overwhelm the faint glow of this object. The single most important thing you need to see the galaxy is a dark sky.

Where is the Andromeda galaxy?

Here’s another way to find the Andromeda galaxy. The constellation Andromeda can be seen as 2 streams of stars extending from one side of the Great Square of Pegasus. See the star Alpheratz? It joins Pegasus to Andromeda Now notice the star Mirach, then Mu Andromedae. An imaginary line drawn through Mirach to Mu points to the Andromeda galaxy.

With the eye, or with binoculars, or with a backyard telescope, the Andromeda galaxy won’t look like the image below. But it will be beautiful. It’ll take your breath away.

How to get to the Andromeda Galaxy?

To get to the Andromeda Galaxy, start at Alpheratz and proceed along the chain past Delta Andromedae to Mirach (Beta Andromedae). At Mirach, hang a sharp right turn to Mu Andromedae, and then go past Mu the same distance as Mirach to Mu. That will put you exactly on the position of the Andromeda Galaxy. Practice these paths several times …

Why is it important to hunt Andromeda?

An absolute essential is a good dark sky. This means getting away from light pollution, which will obscure all but the very brightest deep sky objects. Note that light pollution definitely includes moonlight: one reason for hunting Andromeda tonight is that there will be no moon to spoil the view. You will need a red flashlight to study your chart;

What do you need to study a starhop?

You will need a red flashlight to study your chart; a white light will spoil your dark adaptation and make it impossible to see faint objects. A binocular, 7×50 or 10×50, is very helpful in "practicing" the starhop before you attempt it with your telescope. A hand-held binocular is much easier to handle and point than a mounted telescope.

What is the best tool to use to find stars?

There are several tools which will help this process. The first is a good star chart, such as this one produced by Starry Night. A good star atlas, such as Sky & Telescope’s Pocket Sky Atlas, will do as well.

What is the method used by amateur astronomers to find objects in the sky called?

The method most amateur astronomers use to find objects in the sky is called starhopping. This involves navigation from bright, easily seen objects, stars, to faint, hard-to-see objects, such as galaxies.

What is starhopping in science?

Starhopping involves finding a path from bright star patterns to the fainter objects you are looking for. There is often more than one path to be found, and different observers will find their own paths which work best for them. To get you started, we will talk you through two paths to the Andromeda Galaxy.

Why are all star charts so difficult to read?

The difficulty with all star charts is that they represent the skies on a much smaller scale than the real thing, and beginners often find it difficult to relate the stars they see to the chart on paper. For example, The Square of Pegasus, in the lower right of this chart, is much larger in the sky than it appears on the chart.

What is the most popular target for astrophotography?

Andromeda Galaxy is one of the most popular fall astrophotography targets worldwide, and no wonder! It’s beautiful, bright, and easy to locate in the night sky. If you are a complete beginner in the astrophotography field, but you would love to take a picture of our neighboring galaxy using a DSLR/mirrorless camera and a telephoto lens …

What mount do I need to take pictures of the Andromeda Galaxy?

Unfortunately, to take a good photo of the Andromeda Galaxy with a DSLR or a mirrorless camera, you need an equatorial mount. I use the Fornax Lightrack II mount, but you can select from many other entry-level options, including iOptron SkyTracker, Sky-Watcher Star Adventurer (or a Mini version), or AstroTrac 360.

What camera can I use to capture deep sky?

Almost all of my current wide deep-sky imaging I do with my Rokinon/Samyang 135mm f/2. It’s fast, razor-sharp, and very affordable. And it will capture the Andromeda galaxy with ease in seconds!

What is the resolution of Fuji X-T20?

Fuji X-T20 (APS-C sensor), Rokinon/Samyang 135mm, F/2, ISO 800, 240s, tracked by Fornax Lightrack II. A full resolution (6000 × 4000 px) picture straight from the camera, no crop, no proce ssing. As you can see, a short telephoto lens can reveal this galaxy nicely. And the picture was NOT post-processed in any way. Even a simple one-step background extraction in PixInsight would be a huge improvement.

How many exposures can you do with an astro camera?

If you want to take a high-quality astro picture, then you have to stack many exposures into one frame. You can do, let’s say, 40 exposures manually. But you can just plug an intervalometer into your camera, program it to take exposures you want, and chill on the chair and watch the night sky when your rig is photographing on autopilot for you. I highly recommend using some kind of intervalometer for any astrophotography work.

What mount do I use for a Fornax Lightrack?

I use the Fornax Lightrack II mount, but you can select from many other entry-level options, including iOptron SkyTracker, Sky-Watcher Star Adventurer (or a Mini version), or AstroTrac 360.

When is the Andromeda Galaxy visible?

Andromeda Galaxy Visibility During the Year. The M31 is close to the Polaris, which means it’s visible almost all year! Yet the best time to photograph it on the Northern Hemisphere is from late Summer to Winter when the galaxy is high on the sky.
