EACONN's 80mm refractor is the eighth entry in this guide. It is a fully coated 600mm focal length refractor sold with two eyepieces (K20mm and K9mm), a 5x24 finder scope with crosshair, a phone adapter, a bag and an adjustable tripod, at £69.99. The same EACONN 80mm/600mm refractor with the same K20 and K9 eyepieces turns up twice in this guide, once at £69.99 and once at £99.99. This page covers the £69.99 listing.

Where three of the listings in this guide have an aperture and a focal length that do not agree with each other, this one's numbers hold together. An 80mm aperture on a 600mm focal length is f/7.5. The two eyepieces give 600 ÷ 20 = 30x and 600 ÷ 9 = 66x, which is what the listing claims, and 80mm ÷ 66x = 1.21mm, exactly the exit pupil printed in its spec table. Everything on this page comes from the Amazon listing, not from a test of our own.

## Questions people ask

**What magnification does the EACONN telescope give?**

The listing quotes 30x-66x, from the two supplied eyepieces, K20mm and K9mm, working on the 600mm focal length.

**Do the aperture and focal length agree with the rest of the spec table?**

Yes. An 80mm aperture over a 600mm focal length is f/7.5, the quoted top magnification of 66x comes from the K9mm eyepiece, and 80mm ÷ 66x gives 1.21mm, the listed exit pupil diameter.

**What does the 'Zoom Ratio 64' entry mean?**

The listing states a zoom ratio of 64, but the same listing quotes magnification of 30x-66x from two fixed eyepieces, a range of about 2.2x. The two figures do not agree.

**What comes in the box with the EACONN 80mm refractor?**

Two eyepieces, K20mm and K9mm, a 5x24 finder scope with a crosshair, a customised mobile phone adapter, a bag and an adjustable tripod, according to the listing.

**How heavy is it and how big is it?**

The listing gives an item weight of 3.15 kg and dimensions of 43 cm deep, 12 cm wide and 23 cm high.

**Is it suitable for beginners and children?**

EACONN describes it as easy to assemble for beginners and kids, with a detailed installation manual and video instructions, and the listing presents it as a gift for ages 8-12.
