Top Choices for Telescope Accessories

Some folks consider the telescope accessories in this section necessities. We’ll leave that determination up to you!

Barlow Lens

Planets look very small on nights when the Moon shines at its brightest, so a Barlow lens is a great telescope accessory to help. It enlarges your view with an extra magnifying lens in front of your eyepiece.

A well-made Barlow lens doubles your collection of eyepieces. But, of course, verify you’re purchasing the correct size for your telescope.

Choices like this Celestron Omni 2X Barlow Lens fit into 1.25” focuses and diagonals. It also accepts 1.25” eyepieces, making it a versatile and inexpensive option.

A good pair of binoculars enhances your telescope viewing by giving you a wide field of view. Look for 7×35, 7×50, or 10×50 binoculars for astronomy

You might think bigger is better, but 10×50 is the most potent beginners need. Larger binoculars have narrower fields of vision. Plus, they’re heavier, so they’re harder to hold steady.

Roof-prism and porro-prism binoculars both make excellent astronomy choices. Roof prisms are often lighter and more portable, making them perfect if you also plan to use them for bird-watching. Porro-prisms are a little heavier but have wider views and excellent magnification. 

Bushnell offers roof-prism and porro-prism binoculars that are easy to use and high-quality telescope accessories.

Dew Prevention Shield

Preventing dew keeps you out there star gazing, but once the dampness sets in, you’re pretty much finished for the night. Luckily you have some great choices to shield your telescope from dew. 

First, you can make your own dew shield with just three items.

  • Coffee container to fit your telescope
  • 6mm self-adhesive neoprene
  • 3mm self-adhesive neoprene.

BBC’s Sky Magazine details the steps for this simple dew prevention solution.

Next, you can purchase a dew shield. Or you can get more high-tech with a USB-powered dew heater. Either route you take will improve your night sky observations.

Buying additional eyepieces is part of telescope ownership. Standard 1.25” fitting diameters are universally compatible with telescopes with 1.25” focusers. 

This highly-rated and affordable SVBONY telescope lens set has 4mm, 10mm, and 23mm eyepieces. This focus range suits broad-field Moon viewing, nebulae, and star clusters. As a result, you’ll get more detail across a wide field of view.

Of course, eyepiece price range from affordable to not so much. It all depends on your personal needs and budget.

A good set of color filters make it easier to see detail in the Moon and planets. Buy filters individually or as a set for a better price. Beginners can’t go too far wrong with an entry-level set, but once you’re ready for higher-quality filters, Orion makes excellent ones. They come in a sturdy carrying case with a quick-glance guide showing each filter’s benefit.

Finderscopes point your telescope in the right direction to find celestial objects. The Telrad finder sight (or a similar option) makes an excellent addition to your telescope accessories bundle. And in some cases, it may replace inferior finderscopes.

A multi-degree bullseye helps you target and lock on to your chosen planet or star. So it makes it easy to aim and align your telescope. Protip: Remember to turn off the Fingerscopes (battery-operated) LED when you’re done for the night.
