Frequently Asked Questions (FAQs)

1. Can I use a Barlow lens with any telescope?

Yes, you can use a standard Barlow lens with a refractor, SCT, or other telescopes that use a diagonal. It can be inserted between the telescope and the diagonal or between the diagonal and the eyepiece. However, it is important to be cautious and ensure that the Barlow does not protrude too far into the diagonal, as it may damage the mirror.

2. What is the disadvantage of Barlow lens?

One disadvantage of Barlow lenses is that they add bulk to the setup and can provide narrow views. Barlows with magnification factors of 3x and higher usually have longer barrels, which can protrude more. This can be a concern when stacking multiple Barlows or using larger 2-inch eyepieces.

3. What does 5x Barlow lens do?

A 5x Barlow lens is a magnifying multiplier, not an eyepiece focal length multiplier. It increases the magnification of the telescope by a factor of 5. For example, in a telescope with a focal length of 600mm, using a 25mm eyepiece with a 5x Barlow would result in a magnification of 600/25 or 24x.

4. Why can't I focus my Barlow lens?

If you are having trouble focusing with a Barlow lens, it could be due to the use of a diagonal. Try detaching the diagonal and connect the eyepiece/Barlow directly to the telescope. Although this may result in a less comfortable viewing angle, it often solves the focusing problem.

5. Why is my Barlow lens blurry?

Blurry images with a Barlow lens can be caused by atmospheric conditions such as heat radiating from the ground, high altitude winds, and other weather conditions. These instabilities in the atmosphere can limit the maximum magnification you can use and result in a blurred image.

6. What does a 2 times Barlow lens do?

A 2x Barlow lens doubles the magnification of the eyepiece it is attached to. For example, if you are using a 20mm eyepiece on a telescope with a 1000mm focal length, you would have 50x magnification. Attaching a 2x Barlow lens to that eyepiece would double the effective magnification to 100x.
