What Makes a Deep Space Telescope Different?
Standard telescopes are great for viewing nearby star systems. High-powered models may even give you a glimpse of planets like Jupiter or Saturn, which are hundreds of millions of miles away from the Earth’s surface. But even then, those telescopes don’t hold a candle to deep space devices.
Ultimately, the difference between standard telescopes and deep space telescopes comes down to capabilities. The best telescopes to observe distant galaxies and nebulae are those that offer extremely high magnification power and better light-gathering abilities.
There’s no exact definition for “deep space.” But in the telescope hobby, deep space objects are celestial targets beyond our own solar system. To put it into perspective, the nearest star system to planet Earth is Alpha Centauri. The main star is visible to the naked eye and looks beautiful through a traditional telescope. It’s about 4.367 lightyears away.
The nearest nebula to our planet? That would be the Helix Nebula, also known as God’s Eye. It’s an eyewatering 700 lightyears away! The nearest galaxy is the Andromeda galaxy. It’s 2.537 million lightyears from us!
Traditional star-gazing telescopes won’t be able to help you see those targets. But, a deep space model will.
That’s because they’re designed to gather a lot of light. Even from millions of lightyears away, the light from deep-sky objects eventually makes its way to Earth. The problem is that most telescopes aren’t able to collect it or manipulate it efficiently.
A deep space telescope usually features an ultra-wide aperture and some carefully engineered optics to make those distant targets more visible than ever before.
What Does a Telescope for Deep Space Objects Need?
There are a few important specifications to consider when choosing your deep space telescope. Telescopes can vary widely in terms of design and capability. The following specifications will have the biggest impact on what a telescope can view.
Telescope Types
Before we get into the nitty-gritty, it’s important to understand the difference between core designs. There are a few main telescope designs you’ll encounter.
The first is the refractor telescope. It relies on a series of lenses to manipulate light and magnify the image. There are several sub-categories that telescopes can fall into, but they all still rely on lenses.
The second type of telescope available is a reflecting telescope. These telescopes harness the power of mirrors to create the image. Like refractors, you can get specialty designs. Some options include the Dobsonian reflector and the simpler Newtonian reflector.
Lastly, there are Cassegrains. Cassegrain telescopes are technically reflectors. But, they also use lenses to bounce light uniquely. These models primarily utilize curved mirrors. Schmidt-Cassegrain telescopes use a convex mirror with a corrector plate for a high-quality image. Meanwhile, Maksutov-Cassegrain telescopes use spherical lenses and weak meniscus lenses.
So, which one is best? All core designs are good for deep-sky viewing. What matters most is the key specifications like aperture and focal length.
Wide Aperture
The aperture is the diameter of an optical device’s outermost lens or primary mirror. Refractors have an objective lens. It’s the very first surface that refracted light hits as it enters the telescope. For mirror-based telescopes, the aperture measurement reflects the diameter of the primary mirror.
A wider aperture is key to viewing deep celestial objects. The light that emits from those objects is fainter, so you’re going to need all the help you can get to guide it into your telescope. A wide aperture lets light flood in, which can ultimately improve the clarity and overall brightness of the image.
Long Focal Length
The focal length is the distance that light has to travel within the telescope before creating the image on the focal plane. With a refracting telescope, the focal length is the distance between the objective lens and the focal plane. Usually, the overall length of the optical tube coincides with the focal length.
Refractors are a bit trickier because they bounce light several times before it reaches the focal plane.
Either way, the focal length is a very important measurement for deep space astronomy. This is because it directly impacts magnification power! A higher focal length means that you’re getting more magnification.
Higher Focal Ratio
An easier way to gauge a telescope’s capabilities is to examine the focal ratio. Sometimes referred to as the F-ratio, this is a single number that indicates both focal length and aperture. It’s simply the focal length of the unit divided by the aperture.
A higher focal ratio is best, as it means that you’re getting better magnification. But, the higher ratio also means that you’re getting a narrower field of view.
It’s not easy to get a wide field of view when you’re looking at far-off targets, so this is to be expected. But, it’s still something you should keep in mind.
Other Important Considerations
Beyond the basic specs, you need to take a look at everything a telescope has to offer before committing. Telescopes are complex devices. One low-quality feature could ruin your entire experience as you gaze up at the night sky!
Mounting System
The mounting system is going to play a big role in pointing your telescope in the right direction. We’re not talking about a tripod or base here. The mounting system is what connects the optical tube to your base.
A simple altazimuth mount is just fine for deep-sky viewing. It lets you move horizontally and vertically. For greater precision, look for mounts that have some sort of slow-motion control.
If you want to view the object throughout the night, you may be better off getting an equatorial mount. These mounts have an integrated counterweight and a unique positioning angle. They account for the Earth’s rotation, making tracking your target a cinch.
Finally, there are computerized mounts. As you can guess, these mounts are fully automated. They take out a lot of the guesswork so you can spend less time lining things up and more time enjoying the view.
Technology
Speaking of computerized mounts, advanced technology in your telescope is always a plus! If you’re an amateur astronomer, GPS technology and sky tracking systems can help you find targets in minutes.
Some brands even have large databases filled with thousands of objects to find. Just dial in your target and let the telescope do the rest!
Finder Scopes
A finder scope is the small optical device that attached to the primary optical tube assembly. With lower magnification levels, you can use the finder scope to point your telescope in the right general direction.
Red dot finders take things a step further. With specially coated glass, you can use the scope to line your target up perfectly.
Accessories
Some additional accessories are always welcome. You can get complete kits that have everything you need to start observing the universe. At the very least, we recommend getting telescopes that come with a tripod and protective carrying case.
Having multiple eyepieces is beneficial, too. Different eyepiece sizes and magnifying Barlow lenses can help you get a crystal-clear image.
If you’re a fan of astrophotography, you can also get telescopes with smartphone or camera mounts!
Tips For Viewing Galaxies and Nebulae
For astronomy hobbyists, viewing deep space objects is something that many strive for. It’s easy to point your telescope at the moon. But finding deep space objects and making them clear enough to view? That’s no easy task!
Luckily, the best telescopes for nebulae and galaxies are built to take care of a lot of the hard work for you. That said, there are still some tips and tricks you can follow to get the best results!
Wait for Clear Weather
This tip applies to all stargazing activities. But, it’s even more crucial with very distant targets. Even the slightest cloud covering will get in the way. You need as much light as you can get, so wait until you have a clear and dark night to enjoy the cosmos.
Adjust Your Eyes
Believe it or not, your eyes will continue to adjust after a few minutes. For most people, the pupils dilate enough to let more light in after about 15 minutes. But, your night vision will keep developing for another 90 minutes or so.
When your eyes are adjusted to the dark skies, you can see objects much clearer. Those faint objects become more visible, allowing you to enjoy a better view of all their glory.
For the best results, let your eyes adjust for at least 30 minutes before you start setting your telescope up. Once you have everything aligned and ready to go, your eyes will be ready!
Find the Closest to Complete Darkness You Can Get
This goes without saying, but you need to get as far away from light pollution as possible. We’re not talking about turning off porch lights and going into the backyard. We’re talking about going to a distant hill or hiking up to a mountain.
Light pollution will interfere with the image in your telescope. Make a trip out of it! Go hiking and camp out in an area that’s free of city lights, car headlights, and any other form of illumination.
Use Telescope with Optical Coatings
Many brands these days have telescopes with optical coatings. Anti-reflection and transmission coatings can do a lot to improve the final image. Some of the best transmission-based coatings will allow up to 99.99 percent of all light to come through.
As we mentioned earlier, you need all the help you can get when it comes to light collection. Multi-coated optics will make all the difference.
Conclusion
You don’t need access to the Hubble telescope to view deep space objects! There are many great telescopes on the market to help you appreciate the universe on your own time.
Thanks to advancements in optical technology, stargazing devices are only going to get better. Until then, check out one of our recommended picks to see what galaxies and nebulae you can see!
