Is There a Best Telescope for Astrophotography?
Budget and desired targets are the primary factors. Read on!
Can’t I just throw a dart at a dartboard?
To simplify the choice a bit, if you want to photograph planets or small galaxies, look for longer focal lengths, something near or above 2000 mm would be a good starting point. If you want to image larger galaxies or smaller nebula, go for a medium focal length of 800 to 1200 mm would be a good range. If you want expansive views of large nebula, the Moon or Sun, swaths of the Milky Way, or nightscape photography (celestial objects with landscape backgrounds), go for less than 500 mm. These are not hard and fast numbers since many telescopes fall between those ranges and would do just fine for multiple types of objects.
Keep in mind that these are just general recommendations. Camera sensor size is another factor to consider. For example, a smaller sensor will allow smaller objects to cover the entire sensor. This is similar to the effect of increasing the focal length. By contrast, a larger sensor will make the object look smaller since it will cover less of the sensor. The net effect will be similar to decreasing the focal length. Use a tool like Telescopius.com to get an idea of how a target will be framed depending on the telescope and camera combination.
I understand you’re intrigued by astrophotography. Picture this: capturing the grandeur of a distant galaxy, the radiant dance of a nebula, or the stoic presence of our moon, right from your backyard. It all starts with choosing the right tools, and at the heart of that decision is your telescope.
Astrophotography merges the ancient art of stargazing with modern photography, allowing us to immortalize the night sky’s beauty. You may have a camera ready to go, but the telescope you pair it with can make or break your celestial endeavors. And trust me, selecting a telescope is more complex than picking the one with the shiniest lens; it’s about matching your intent with function.
Typically, we have three primary workhorses in the realm of telescopes for astrophotography: refractors, reflectors, and compound telescopes. The most common type of compound telescope is the catadioptric telescope. Each shines in its own right, depending on what you aim to capture.
Are They Expensive?
Your wallet isn’t forgotten in this equation either. Balancing price with performance is essential; after all, a telescope is an investment. You’ll find solutions for every budget, from entry-level scopes that offer a window to the cosmos without breaking the bank to those high-ticket devices that promise features cosmic enthusiasts dream about. Keep in mind that you generally get what you pay for. Some very inexpensive telescopes make all kinds of promises, and there is just no way they can deliver. That’s not to say that quality can’t be found at affordable prices.
I’ve set the stage with must-know information. Now, keep these takeaways in mind as you prepare to navigate the market. Learners like you will soon understand how different telescope features align with your astrophotography goals, and you will step closer to capturing the night sky with clarity and brilliance.
Navigating the Market: How Telescope Features Align with Astrophotography Goals
Astrophotography isn’t just about pointing a telescope skyward and snapping a picture; it’s a delicate blend of art and science. Every aspiring astrophotographer should know how critical telescope features are to the end result. You’ll want to pick a telescope that not only suits your current skill level but also your future aspirations as an enthusiast. I would argue that your desired targets should really impact the type and size of telescope you purchase. Once you make that decision, price should come into play.
A telescope is a telescope, right?
The nature of refractor optics and cost limit the aperture of the scope. Because it is a straight-line light path, the focal length really limits the length that can be used for home or remote purposes. At a certain length, a refractor would become unwieldy. Because of the shorter focal lengths, these scopes are best suited for larger objects like nebulae and larger galaxies or the moon. In theory, refractors, known for their clarity and contrast, are ideal for high-resolution images of planets and the moon. Although the lack of a central obstruction makes for great contrast in planetary images, the small size of planets requires a long focal length. Refractors can only achieve this with a Barlow lens to extend the effective focal length.
Reflectors, on the other hand, offer larger apertures at a reduced cost, making them suitable for both planetary and deep-sky imaging. The folded light path makes longer focal lengths achievable, so planetary imaging becomes doable without Barlow lenses that might otherwise be necessary to extend the focal length.
Compound telescopes offer the best of both worlds, with built-in features that cater to advanced astrophotography techniques. The folded light path makes long focal lengths inherent to the design. Despite the central obstruction to the light path, compound telescopes are very suitable for both planetary photography and smaller deep sky target photography.
The aperture size, which refers to the diameter of the telescope’s primary optical component, is an important consideration when capturing celestial details. A larger aperture enables more light to enter the telescope, which is crucial when you’re trying to photograph distant and dim celestial objects. This is why reflectors and refractors excel in light gathering because of the large affordable apertures that are possible.
It’s also crucial to consider how well a telescope will work with the additional gear you’ll need. Most accessories that attach directly to the telescope come in 1.25-inch diameter or 2-inch varieties. If you are serious about getting good results, go for the 2-inch connection since we already know that a larger aperture means more light gathering.
Also, think about compatibility with cameras, laptops, and specialized filters – all of which can make or break your astrophotographic venture. This is especially true if you already own some equipment. Unless you want to start from scratch, make sure everything “fits”.
Lastly, although it might be tempting to rush into a purchase, take your time. Weigh the features against your goals. Research and join communities to learn from experienced astrophotographers who often share valuable insights. Doing your homework will pay dividends when you capture those awe-inspiring images of our universe.

When it comes down to it, the best telescope for astrophotography is one that meets your personal ambitions and fits your budget. If you’re just starting out, don’t get overwhelmed by the most sophisticated equipment out there. A modest refractor (say 80-90 mm aperture) or a small-aperture reflector (say 4 to 6 inches) can do wonders as you learn the basics.
For those with intermediate experience, a mid-range telescope offers a great middle ground. This could be a larger aperture reflector or an advanced compound telescope with a computerized mount. Such telescopes provide brighter images and the ability to target fainter objects.
Veteran astrophotographers will likely look for more sophisticated equipment. The investment in a high-end telescope pays off with exceptional quality A large aperture and high-quality optics are typically non-negotiable features for serious enthusiasts focused on capturing specific or dim celestial bodies.
Remember, no matter the level you’re at, investing in your knowledge and skills is just as crucial as the equipment. Exploring forums, books, and tutorials can be INVALUABLE. Networking with the astrophotography community can provide insights into making the most of your telescope. Don’t be afraid to ask specific questions right here at Astrophotoguru.com.
Before making a purchase, consider product reviews and ask for recommendations. Don’t hesitate to experience the telescope hands-on if possible. Sometimes the ‘feel’ of the equipment can be the final deciding factor.
The universe is vast, and so are the possibilities in astrophotography. With the right combination of equipment, knowledge, and passion, you can capture the marvels of the night sky. The perfect telescope for you is out there; it’s just a matter of matching it to your dreams and giving yourself the permission to reach for the stars.
