Should You Buy A Used Telescope? The Pros & Cons

If you are an aspiring astronomer, you might be wondering whether you should buy a used telescope or a brand new one. The truth is, buying a used telescope can be a great way to save money while still getting a high-quality instrument. However, there are several things you need to consider before making your purchase.

First and foremost, you need to decide what type of telescope you want. There are three main types: refracting, reflecting, and catadioptric. Each type has its own advantages and disadvantages, so it’s important to do your research and figure out which one is right for you. Once you’ve decided on a type, you can start looking for used telescopes that fit your needs.

Factors to Consider


When it comes to buying a used telescope, your budget is one of the most important factors to consider. Telescopes can range in price from under $100 to over $10,000, depending on the type, brand, and features. Determine how much you are willing to spend before you start your search. Keep in mind that a good price range for a used telescope is between $200 and $300.

Condition of the Telescope

The condition of the telescope is another important factor to consider. Check for scratches, dents, or other damage to the body and lenses. Look for signs of wear and tear, such as rust or corrosion. If you are buying a reflector telescope, check the mirrors for dirt or scratches. It is also important to check the mount and make sure it is stable and sturdy.

Type of Telescope

There are three main types of telescopes: refractor, reflector, and compound. Refractor telescopes use lenses to focus light and are great for viewing planets and stars. Reflector telescopes use mirrors to focus light and are ideal for deep-sky objects. Compound telescopes use a combination of lenses and mirrors and are versatile for both planetary and deep-sky viewing. Consider which type of telescope best fits your needs and interests.

Brand and Model

Brands and models can vary greatly in terms of quality and features. Do your research and read reviews before making a purchase. Some popular brands include Celestron, Meade, and Orion. Look for models that have a good reputation for performance and durability.

Accessories and Extras

Consider what accessories and extras come with the telescope. Some telescopes come with eyepieces, filters, and carrying cases. These can be valuable additions and save you money in the long run. Look for telescopes that come with a warranty or return policy in case you are not satisfied with your purchase.

Pros and Cons of Buying a Used Telescope


Buying a used telescope can be a great way to save money while still getting a quality instrument. Here are some advantages to consider:

  • Lower cost: One of the most significant advantages of buying a used telescope is the cost savings. You can often find a used telescope for a fraction of the cost of a new one, which can be especially helpful if you’re just starting out and don’t want to invest too much money upfront.
  • Access to higher-end models: If you’re interested in a high-end telescope but can’t afford to buy it new, you may be able to find a used one for a more reasonable price. This can allow you to get a better instrument than you would be able to afford otherwise.
  • Less depreciation: Telescopes hold their value well, so if you decide to sell your used telescope later, you may be able to recoup most of your investment.


While there are many advantages to buying a used telescope, there are also some potential downsides to consider:

  • Uncertainty about condition: When you buy a used telescope, you don’t always know how well it has been cared for or if there are any hidden issues. It’s important to thoroughly inspect the telescope before you buy it and ask the seller any questions you have about its condition.
  • Limited warranty: Used telescopes typically come with little to no warranty, which means that if something goes wrong, you may have to pay for repairs out of pocket.
  • Outdated technology: Depending on how old the telescope is, it may not have the latest technology or features. This could be a disadvantage if you’re interested in using your telescope for specific types of observations.

Where to Buy a Used Telescope

If you’re considering buying a used telescope, there are several places you can look. Here are some of the most common options:

Online Marketplaces

Online marketplaces like eBay, Amazon, and Astromart offer a wide range of used telescopes and accessories. These sites often have a large selection, which can make it easier to find the specific telescope you’re looking for, and prices can be very competitive. However, you should be careful when buying from an individual seller, as you won’t have the opportunity to inspect the telescope in person before purchasing it. Make sure to read the seller’s reviews and ask for detailed photos and information about the condition of the telescope.

Astronomy Clubs and Forums

Many astronomy clubs have classified sections on their websites or forums where members can buy and sell used equipment. This can be a great option if you’re looking for a specific type of telescope or accessory, as other club members may be able to offer advice or recommendations. Additionally, buying from a fellow astronomy enthusiast can give you peace of mind, as they are likely to have taken good care of their equipment.

Local Classifieds and Garage Sales

Checking local classifieds or garage sales can be a good way to find a used telescope at a lower price. However, the selection may be limited, and it can be difficult to find a seller who is knowledgeable about telescopes. Make sure to thoroughly inspect the telescope before purchasing it, and ask the seller about its history and condition.

When buying a used telescope, it’s important to do your research and make sure you’re getting a good deal. Take the time to compare prices and read reviews, and don’t be afraid to ask questions before making a purchase. With a little patience and careful consideration, you can find a high-quality used telescope that will provide years of stargazing enjoyment.

Tips for Inspecting a Used Telescope

When buying a used telescope, it is important to thoroughly inspect it to ensure that it is in good condition and will meet your needs. Here are some tips to help you inspect a used telescope:

Physical Inspection

Start by examining the telescope’s physical condition. Check for any dents, scratches, or other damage to the tube, mount, and accessories. Look for signs of rust or corrosion, which can indicate that the telescope has not been well cared for. If the telescope has been stored in a damp environment, there may be mold or mildew on the optics or other parts.

Next, check the eyepiece and focuser. Make sure that the eyepiece is securely attached and that the focuser moves smoothly and without any resistance. Test the drawtube to make sure that it extends and retracts smoothly.

Optical Inspection

Inspect the optics carefully to ensure that they are in good condition. Look for scratches, chips, or other damage to the lenses or mirrors. Check for any signs of degradation, such as fungus or haze, which can affect the telescope’s performance. If possible, use a flashlight to shine light through the optics to check for any defects.

When inspecting the optics, also check the alignment of the mirrors or lenses. If the optics are misaligned, this can affect the telescope’s performance and may require expensive repairs.

Testing the Telescope

Finally, test the telescope to ensure that it is working properly. If possible, take the telescope outside and test it under the stars. Check the focus and make sure that the image is sharp and clear. Move the telescope around and test the tracking to ensure that it is working properly. If the telescope has a motorized mount, test the motors to make sure that they are working smoothly and without any noise.

If you are unable to test the telescope under the stars, you can still test it indoors. Point the telescope at a distant object, such as a tree or building, and check the focus and image quality. Move the telescope around and test the tracking to ensure that it is working properly.

By following these tips, you can ensure that you are buying a used telescope that is in good condition and will provide you with many years of enjoyment.


When it comes to buying a used telescope, there are certainly some advantages. You can save a lot of money and potentially get a higher quality telescope than you would be able to afford if you were buying new. However, there are also some risks involved.

Before making a purchase, it’s important to do your research and make sure you’re buying from a reputable seller. You should also carefully inspect the telescope to make sure it’s in good condition and functions properly. If possible, try to test it out before buying.

Another important factor to consider is the type of telescope you’re buying. Refractor telescopes are generally more reliable and less likely to have issues than reflector telescopes. Additionally, it’s important to make sure the mount is in good condition, as a faulty mount can make it difficult to use the telescope effectively.

Ultimately, whether or not you should buy a used telescope depends on your personal preferences and priorities. If you’re willing to take on some risk and do your due diligence, a used telescope can be a great way to save money and get a high-quality instrument. However, if you’re not comfortable with the potential risks, it may be better to invest in a new telescope instead.
