Best Overall: Orion quality Barlow len

Buy on Amazon

Here, we present len that manages to win our hearts. It's the orion quality barlow len and it's widely considered as one of all-around great len you can buy. If you wear glasses, a Barlow saves you from having to use a short focal length eyepiece (with short Eye Relief) to double the power. It is small and light, and the eyepiece rests firmly in it. It is great with web cam for planetary imaging. It is great for looking out at ships way out on the water.

Not only does the orion shorty 2x barlow's power-boosting ability mean you can enjoy two different viewing magnifications with each 1.25 inch telescope eyepiece in your collection, but the shorty barlow can also make observing at high powers more comfortable. If you have a telescope, this is a MUST accessory.

• Works well for over land/sea and the stars
• Doubles power with easy change over
• Delivers what they promise

Best For many eyepiece attachments: Celestron quality Barlow len

Buy on Amazon

The celestron quality barlow len's superior materials makes sure that it ages well with use. It is great to improve night viewing of stars and planets. This particular one uses common 1.25 inch eyepieces, and the receiver on your telescope needs to be the same. It features a 1.25" eyepiece adapter. The 1.25” barrel will fit in standard 1.25” focusers and diagonals, and the Barlow will accept 1.25” eyepieces. It will instantly double the power of whatever eyepiece you have (20mm, 10mm, etc,) and enable you to really see things a lot better.

When you put this barlow in, the lens takes the last few cm of that cone and stretches it, lowering that angle, so your scope acts as if it is twice as long with the same size mirror/objective lens, thus doubling its f number. The scope actually turned out quite nice, but with its short focal length, the effective magnifications even with a 4mm eyepiece were pretty low. It comes with a lot of ota's and all in one telescope kits.

• Pairs well with the omni-series plössl eyepieces
• Larger barrel, rubber hand grip, brass compression ring to safely grasp heavy eyepieces
• Noticeable chromatic aberration compared with the cheaper barlows

Best with certain eyepieces: SVBONY quality Barlow len

Buy on Amazon

We know from years of feedback from readers, customers and amazon sellers, what most people want in a convenient and appropriate len. The svbony quality barlow len is exactly that - it's a simple len that hits all the right notes. The difference between the two Barlow lens is that magnify the magnification of the telescope by 2 and 5 times again. This barlow has 5x etched on the side but produces 3x images. It fits over an eyepiece and is a magnifier. It fits most celestron scopes.

The Orion Starblast focal length is only 450mm and useful magnification is. It is a little long and heavy, but it gives high magnification power and clear image quality only for $. This lens is really good because it brings the moon up way closer makes it easier to see the details for an excellent purchase.

You can feel the quality when you handle this all-metal 2" 2x Barlow lens. It's sturdy, well constructed.
