Andromeda Galaxy is one of the most popular 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 or a telescope, here you have the complete guide to photographing the Andromeda Galaxy.

Andromeda Galaxy Facts
The Andromeda galaxy is our nearest spiral galaxy neighbor, but the closest galaxy in general to our own is the Canis Major Dwarf Galaxy. Also, the M31 is one of the brightest objects on the night sky, which means that you can photograph it very fast (in minutes, not hours).
Yes, even with naked eyes, if you are in a dark place (outside of the city). A pair of good astronomy binoculars is helpful, but not mandatory.

How to Find the Andromeda Galaxy (Location on Sky)
The M31 is located in the constellation Andromeda, close to Perseus and Cassiopeia. Finding it is quite easy as the M31 is visible by the naked eye (outside of the city). You can easily observe the Andromeda Galaxy using binoculars.
If you are not familiar with the night sky, then I recommend you to use software that will help you in locating astronomical objects. For iPhone and iPad users, I have my astronomy apps for iPhone compilation. If you are not an Apple user, then you can use some multi-platform apps like Stellarium.
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. Generally, the lower the designated photography object is in the sky, the more work you will have in post-processing, and the worse effects you will have. Higher the object on the sky = less atmosphere, and less light pollution. So reserve some time during August to December and shoot the Andromeda galaxy then.
Andromeda Galaxy Through a Telephoto Lens
The biggest surprise for a lot of people is you don't need to use a telescope to photograph the Andromeda Galaxy! Of course, if you have a small refractor scope, you can use it, the final picture resolution will be higher. But to reveal some details of the Andromeda Galaxy, the only piece of optics you need is a telephoto lens!
- Rokinon Ultra Multi-Coated (UMC) Optics. One extra-low dispersion (ED) lens element reduces chromatic aberrations
- Minimum Focusing Distance of 2.6 ft. with fast apertures of f2.0 - f22
- Features 9 diaphragm blades and includes a removable lens hood
- Includes lens pouch, front and rear lens caps, removable lens hood and 1 year Rokinon warranty
Astrophotography Equipment for Photographing the M31
Cooled, expensive astronomical CCD cameras are not needed! Andromeda galaxy, thanks to its brightness, is a perfect astrophotography target for simple DSLR and mirrorless cameras. Almost every Canon, Nikon, Fuji, Olympus, Panasonic, and many other cameras from this decade can perfectly capture this galaxy. So don't rush to the photo store, use what you already have.
If you don't yet have any photography gear and you are looking for some advice, then check out my beginner astrophotography equipment guide.
As I said before, you don't have to have a telescope to photograph the Andromeda galaxy. Of course, it all depends on the level of detail you want to capture. The longer the focal length, the bigger "zoom" you have. But to photograph some level of details, I recommend a minimum 90mm lens.
Using the astrophotography "500 rule" and, let's say, a 100mm lens, theoretically you can photograph the M31 without an equatorial mount. Calculate exposure time (500/100 = 5s), set very high ISO, and you are done. But the truth is, you won't capture any details on such short exposure time like this. 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.
- PORTABLE NIGHTSCAPE TRACKING PLATFORM: Motorized portable tracking platform perfect for capturing incredible detail of the Milky Way, eclipses and other astronomical objects
- BUILT-IN ILLUMINATED POLAR FINDERSCOPE: The included illuminated polar finderscope allows for easy and accurate alignment with Polaris.
- RUGGED BRASS AND ALUMINUM GEARS: Using rugged brass and aluminum gears provide smooth, motorized, night sky tracking for easy, portable nightscape and eclipse photography.
- BUILT-IN AA BATTERY COMPARTMENT: The built-in AA battery compartment provides reliable mobile power for up to 72 hours, and an additional 5v mini-USB input allows for external power source using a cell phone charger or other device.
- LIGHTWEIGHT AND PORTABLE: Weighing just 2.4 lbs, the Star Adventurer is lightweight and portable enough to pack in a camera bag or backpack for astrophotography on the go.
A Stable Tripod
I used to use a cheap tripod for my wide-field (135mm) deep-sky astrophotography. In quietly, non-windy conditions, it worked. But any small breeze appeared, and my exposures were blurred. Today I use a very stable Manfrotto 475B and those annoying nights are gone.
- Slim profile shoulder - allows for the tripod legs to be more compact when folded.
- Anodized aluminum twist locks - only require a quick half turn to lock and unlock.
- Arce-Swiss style camera plate - Blue anodized aluminum Arce-Swiss style quick release plate with a d-ring 1/4"-20 camera screw.
- Lightweight magnesium shoulder - features 3 leg positions and each leg can be positioned individually for uneven terrain.
- Removable single action Billhead - Oversized ratchet style lock knob for easy operation and a panoramic scale.
- All black anodized aluminum construction and unrivaled in stability
- Unique center brace strut system
- Reliable quick-action leg locks
- Non-rollback three-faceted center column, spirit level and rubber/metal spiked feet
- 74-inch maximum height with center column, 26.5-pound maximum load
An Intervalometer (Optional)
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.
Andromeda Galaxy Photography Settings
Generally, camera settings for deep-sky astrophotography depend on many factors:
- Camera's sensor noise
- Lens focal length
- Lens aperture
- Equatorial mount Periodic Error
I am not able to tell you what exact settings should you set your camera on. But I can give you a starting point to experiment with:
|Exposure time||2 minutes (120 seconds)|
If you have a 2.8 lens, then set ISO to 1600 OR extend the exposure time to 4 minutes (240s). Also, check twice that you shoot in the RAW mode because that way you will get the maximum quality. JPGs are not that good as RAWs.

Andromeda Galaxy through a telescope
As you can have really nice results with a telephoto lens, using a small APO telescope will set the game to a whole new level.
