Celestron 93325 1-1/4-40 mm Omni Series Eyepiece

Great wide field lens for Celestron 6se telescope. I use it every time I take the scope out. Feels like solid quality and image is great. Can get a large amount of Plaides and Andromeda but not all of them. Awesome for comets, clusters, other larger objects.

First off, let me start this review by saying, for an eyepiece made in China, this thing feels very well built. It's solid in your hand, actually weighs a good bit for an eyepiece. The view is incredibly clear, and the field of view is very wide. This is great for viewing large swaths of the sky at a time, not so good for small targets like planets. This is more of a nebula/star cluster eyepiece. It is a plossl design, so there are two doublet lenses inside. It added no extra chromatic abberation, so it's perfect for reflector and Cassegrain telescopes that don't produce CA on their own. On my 102mm refractor, the views were great, but because that scope is an achromat, there was chromatic abberation, but not from the eyepiece. For under $50, I can't see why you wouldn't buy one of these if you're on a budget. Eye relief is about an inch, so you don't have to hold your eye on the glass for once.

A surprisingly good optic. Great finish, overall a very good low power eyepiece for the price. I use it primarily to center objects before increasing power with other eyepieces. Would definitely buy again.

I bought this to go with my new Celestron 130EQ 5-inch reflector so that I could have the widest possible actual field of view. Images were bright, flat, and well focused throughout the entire visual field. However, I ended up having to return this eyepiece because the resulting 16x magnification was just under the usable magnification for this scope and I would see a blurry shadow of the secondary mirror and support if my eye got too far from the eyepiece. I bought a Newer 38mm instead...which I hope will be as good visually but not show the diagonal mirror [enough to be annoying].

I like the way these eyepieces are made. They are high quality and well built. I like the lower power eyepieces, due to the wide field of view. These Celestron Omni eyepieces are in my opinion, the best bang for the buck, providing clear and sharp views.

I bought this 40mm lense for use with my 127mm(5 inch) Newtonian Reflector.I wanted something that would gather as much light as possible, for viewing deep sky objects, such as Galaxies, Nebulae, and Globular Clusters.The Celestron Omni series 40mm was perfect for this application.I can see quite a few deep sky objects through this lens that were nearly invisible through smaller lenses I own.It also lends a great amount of clarity too the easier ones like The Orion Nebula.The Omni Series is a great line of high quality lenses for hobbyist prices.The lens is made of metal, not plastic, and is made with fairly rugged design.It could survive an accidental drop, as mine unfortunately has.It still works perfectly.The rubber eyepiece folds out, which works great, and has not shown any age or wear after a year and a half of use.I recommend it.

Looking at the stars at night, nothing beats a good time with a telescope. The Moon, in particular, is my favorite astronomic object to look at... Recently, I got a Newtonian Reflective Telescope from a buddy of mine but all of the eyepieces he had were the kind that you need to have your eye almost touching the eyepiece. So I wanted a brighter and easier-t-use eye piece. This is it! It's definitely beginner friendly and the 40mm size made for wonderfully bright images. Also makes it much easier (it's still tricky) to take photos of the Moon with a phone. Not for gazing at the rings of Saturn, but perfect for staring at the Moon.

Longer focal length eyepieces often get overlooked, especially by those just getting started in amateur astronomy. Most beginner astronomy kits (Optical Tube Assembly w/finderscope, mount, eyepieces) usually include two focal lengths to get you started: a 25mm and a 10mm. My own experience tells me that anyone who wants to start a successful observing run needs to have a 40mm eyepiece to perform field narrowing from finderscope to eyepiece. a 40mm may not exactly be an "observer's eyepiece" except for the most extended objects, but it is an absolute must-have to narrow the field around a target. In fact, since I typically run several rigs at once at my college's star parties, I found that I needed to have at least two of these eyepieces. I already had a Sirius Plossl 40mm from Orion, and the Celestron Omni is an equivalent (nay, nearly identical) optical stack to work with a second 'scope, so I wouldn't have to keep hunting for a 40 when acquiring a target in the eyepiece. This is a great, yet often overlooked, workhorse eyepiece.

Excelente opción para tu telescopio

Aunque el angulo de visión no es muy alto, poco mas de 40º, la definicion, la nitidez y el contraste son excelentes. Es un muy buen ocular para la localizacion de los objetos. Es muy recomendable para telescopios de f alto, en los de focal corta puede dar alguna distorsion muy al borde, aunque casi inapreciable. En resumen un buen ocular.

ممتازة

Excelente ocular para centrar objetos, ver campos amplios de estrellas, nebulosas y la luna.
