Get PriceBarlow Lens vs Eyepiece – Magnification Battle
20mm eyepiece + 2x barlow = 100x magnification. 10mm eyepiece + 2x barlow = 200x magnification. The telescope's focal length doubled (from 1000mm to 2000mm), hence the double magnification with the same eyepieces. Now you have 4 eyepieces and 4 magnifications using one Barlow lens. Another advantage here is that you can use an eyepiece with ...
Get PriceGuide to Focal Length in Photography (+ 7 FAQs)
For example, a typical zoom lens might have a focal length of 18-55mm, or 24-70mm. Focal length comes from the distance between a specific part of a lens (the 'optical centre') and the image sensor (or film plane) where the image is recorded. The wider the angle of view that a lens offers, the smaller this distance, and the lower the number.
Get PriceHow To Increase The Magnification Of a Telescope
Dividing the 1000mm focal length by 10mm and 20mm eyepiece results in 100x magnification with 10mm eyepiece and 50x magnification with 20mm eyepiece. As you can see, it is essential to have more eyepieces if you want different magnifications. Using a shorter focal length of the eyepiece is increasing the magnification of the telescope.
