What is Astronomy?
Many people have an incorrect definition of what Astronomy is. Astronomy is the study of the planets, cosmos, and space. This includes gas, dust, comets along with other things. If you’re looking for a simpler definition, NASA defines astronomy as, “the study of stars, planets, and space.”
Years ago, scientists classified astronomy and astrology in the same class. Unfortunately, this is no longer the case due to astrology not being an official science. Astronomy and astrology are no longer associated with each other in the science community.
If you’re a person whos’ interested in Astronomy, continue reading. In this article, we’re going to list the best spotting scope for astronomy. We’ll discuss anything you need to know.

What is a Spotting Scope?
To put it simply, a spotting scope is a small telescope. The difference between a telescope and a spotting scope is designed for day use. They’re used for hunting, birding, scenery watch, and target shooting.
There are other factors that make spotting scopes different from telescopes. Firstly, spotting scopes produce upright images, and telescopes for astronomy produce reversed (and upside down) images. Secondly, spotting scopes are smaller and designed for portability. Thirdly, a spotting scope has a far lower magnification level than a normal telescope. Furthermore, spotting scopes can be mounted on camera tripods. Telescopes, on the other hand, require specific mounts.
I thought we’d include that most, if not all, spotting scopes are waterproof, shock-proof, and fog-proof. This is mainly due to the fact spotting scopes are designed for more “physical” activities such as hunting, birding, target shooting, and many other things. Personally, I have yet to see an astronomy-based telescope that has these features. We’re not saying it’s possible, but it’s rare.
Here’s a list of activities spotting scopes is used for:
- Birding
- Surveillance
- Archey
- Target Shooting
- Hunting
- Viewing Landscapes
- Some Astronomy
- Long-distance Photography
People who are looking for extra magnification go for a spotting scope. Binoculars do not have the magnification power of a spotting scope.
With spotting scopes, there are three numbers you should pay attention to. The first two numbers represent the range of magnification. The last number represents the size of the front lens. For example, Gosky HD Porro Prism Spotting Scope (15-45×60), means this spotting scope has a zoom magnification range of 15-45x and the front lens has a diameter of 60mm.
Magnification
The magnification of a spotting scope is what separates it from binoculars. The higher magnification of a spotting scope, the better. There are two things you should keep in mind when it comes to a spotting scope’s magnification.
You always should keep in mind the atmosphere you’re in. Are you going to be in a hot condition with heat waves? Dusty desert? Snow? Basically, many weather factors that can affect the scenery. These weather conditions affect the quality of your image. Not only that but with greater magnification, the worst your image quality gets.
Dry high altitudes climates thrive with high magnification levels. Low wet, humid low-altitude climates fail with high magnification levels. Always remember this. It’s very rare for a location that requires more than 60-80x during the day. If you have a spotting scope that maxes out at 60-80x should be fine.
The optical system within a scope is the second major limit. No matter the model or brand, image quality goes down as the magnification goes up. Period. This is the fault of the optical system in place.
Objective Lens
The bigger the objective lens, the better the image quality. You’ll see more details, clarity, and color depth. But, bigger doesn’t always mean better. A big cheap lens, no matter how big, will never be as good a small higher-end lens. Like all things, never just buy off size but the quality of the product.
The performance of all spotting scopes can be improved with special quality glass (HD glass, ED glass, APO glass, Fluorite glass) in the objective lens. Obviously, there will be an additional cost but it’s possible.
Straight vs Angled
Most manufacturers create two spotting scope styles which are straight and angled. If you want to know which is better for you, continue reading. There are a few things to consider when you’re talking about angled and straight spotting scopes. If you generally go scoping solo and use a tall tripod, you may want to use straight spotting scopes. Plus, straight spotting scopes are great for a downwards view.
If you’re looking for a scoping scope for multiple people, an angled is the way to go. Especially if the size of the people is different heights. In my opinion, an angled eyepiece works better for an upward view.
Eye Relief
This is important for all buyers to remember. Eye Relief is the distance your eye can be from the actual eyepiece on a spotting scope. This important is important for users who wear glasses. Due to the fact they can’t immerse their eye in the eyepiece like non-glass-wearing users.
We recommend users with eyeglasses get a spotting scope with at least 14mm of eye relief. If you have very thick glasses, you’ll need to get a spotting scope with bigger eye relief.
Lens Coatings
When you’re buying a spotting scope please pay attention to lens coating. The lens coating basically improves light transmission within the spotting scope. Why is this important? It’s important because it increases the quality and performance of the spotting scope.
There are 3 types of coatings you’ll find on the market. The first one is the “fully coated”, the second is the “multi-coated”, and lastly, is the “fully multi-coated”. All truly high-end spotting scopes will be “fully multi-coated. All manufacturers use different methods and chemicals for their coatings.
Image Quality
“You get what you pay for..” is what it is in the spotting scope world. Obviously, this is a universal saying but it’s absolutely true with spotting scopes. There’s always a large gap in performance and price. This applies to low-quality recreational scopes and high-grade scopes for serious hobbyists.
We don’t want to scare you away from spotting scopes or anything. For many users, you can get by with low to medium-priced spotting scopes. But, don’t expect super great quality performance or images.
Cheaper vs. Expensive: Spotting Scopes
There’s a big difference between inexpensive and expensive spotting scopes. With “cheaper” spotting scopes, the image quality gets lost faster as magnification goes up. This doesn’t matter if it’s big or small or the type of scoping scope it is. Cheaper spotting scopes lose image quality faster than expensive scopes.
With higher-end spotting scopes, you lose very little image quality during heighten magnification. Image quality is still lost but by a small margin. But, you have to remember, with higher-end spotting scopes, you will be paying a lot more.
If you’re an avid enthusiast, invest in a high-quality spotting scope. If not, go with a cheaper option. Most observing activities such as birding, hunting, and target shooting are done at low magnification levels. This is about 30x-40x on a magnification scale.
Can You Use a Spotting Scope for Astronomy?
Yes, but to an extent. If you’re getting a spotting scope mainly for astronomy, get a telescope. If you’re looking for a spotting scope for flexible uses like birding, hunting, and the occasional astronomy, that’s a different story.
Remember: the larger the aperture on your scope, the more light you can capture. This is crucial at night if you’re using it for astronomy. An objective lens of at least 65-70mm is required for basic astronomical uses. You need to also remember using a spotting scope at nighttime pushes the capabilities to their limits.
If you plan on getting a spotting scope for astronomy, it’s preferred you get a high-end model. Get a scope higher quality optics, fully multi-coating, and a high-quality ED glass.
So, can a spotting scope be used for astronomy? Yes, it can but there are other scopes (telescopes) that are better for astronomy. If you want to learn how our recommendations for spotting scopes for astronomy continue reading.
Conclusion
So, are spotting scopes good for astronomy? Absolutely. Spotting scopes can be used for astronomy but they aren’t the most qualified for the task. If you’re an avid hunter, wildlife observer, and/or target shooter but need a device for both astronomy, then the above recommendations should be strongly considered.
In my opinion, hands down the Celestron 52306 Regal M2 100ED Spotting Scope is the best spotting scope for astronomical uses. But, even though it’s my top recommendation, I still recommend getting a telescope if that’s your main driver here. My second recommendation would be the Celestron Ultima 100 Angled Spotting Scope if you’re looking for something more budget-friendly.
