SVBONY 40mm 1.25" Plossl Telescope Eyepiece Fully Multi Green Coated Metal 40 Degree Apparent Field 4 Element for Astronomy Telescope

Muy buena calidad de imagen, tiene un campo de visión amplio ideal para observación lunar y planetaria.

Impressive quality as to materials and build. Solid metal and multi-coated glass. Blackened internally to reduce stray light reflections. I have yet to view through it in the field, but am very confident that I will be very pleased, based on a thorough review by my highly trusted and very reliable YouTube reviewer, Jason of Small Optics. I purchased a second one for my neighbors, who are giving their young daughters a Celestron beginners' refractor telescope for Christmas 2023. A 40mm eyepiece is a great tool to be used with the stock eyepieces of any beginner scope or with more advanced scopes, as it provides a wider view of the sky. That wider view enables one to be well-oriented as to where to look and move the scope for bringing desired viewing targets into the center of the telescope's view. Then, one can simply lock the scope to that position, then replace the 40mm eyepiece with a 25mm, 10mm, etc. for greater magnification of the desired target, loosen locks of telescope, and off to viewing the target close up with the more powerful stock eyepiece. Alternatively, the 40mm can help provide beautiful sweeping vistas for those who enjoy simply scanning the night sky full of many more beautiful stars, planets, and clusters, etc. than the naked human eye can ever detect.

Hi I bought 2 for my binoculars wasn't quite confident for the price.but better than some of my expensive eyepieces

The 25mm eyepiece magnifies too much for Pleaides, which touches the perimeter of the field of view for my 10" Newtonian telescope. This 40mm eyepiece is better for magnification of larger fields of view. Nearby Jupiter and 4 of its moons are a great deal less across and need the 25mm because the 40mm isn't enough.

The field of view is sharp from edge to edge. I feel like I have a better view with this eyepiece than using a 25mm or 18 mm eyepiece because it’s so much clearer.
