Celestron 93430 7 mm Luminos Eyepiece,Silver/Black

Good delivery, good service. Great product

When I first bought my telescope the shop and other astronomers said, get good eyepieces as when you upgrade kit your eyepieces tend to stay with you. Added to the fact that when you look through cheap optics you will be doing the glorious heaven a injustice. I have the 7mm, 10mm, 19mm and 31mm Luminos's that I use on my Celestron Edge 8 HD and now I have the 15mm. I can honestly say that I'm not disappointed with any of them. The build quality is excellent and being of aluminium/alloy construction so they are a bit more hefty than many other eyepieces, especially Plossls and cheap eyepieces. I get no issues with clarity almost all the way across the FOV with just slight abberations at the edges. Looking through these EP's is like looking into a bucket rather than the spyhole feeling with Plossls. The 80+ degree FOV is truly amazing and you have to look around inside the eyepiece to see everything. There is a retractable eyecup if you wear spectacles and the whole range of Luminos EP's are Parfocal, which means when swapping between EP's you virtually haven't got to refocus. A word of warning the 31mm is mahoosive. It's the size of a cola can and weighs in at over 1Kg!!

I love this eye piece for seeing the moon crater, it's such a wide view for the 1.25 fitting, you may get about a minute of viewing before having to adjust your mount, unless you're lucky enough to have an electric mount, which wouldn't matter in that case. You get a lot closer with this 10mm but have a view much similar in width as if you where using a 15mm for example. The rubber eyepiece adjustment is great because I use glasses and it stops me worrying about damaging them. Now i've had this for over a year the planets are a bit small to see but can be viewed, i have a 2 x barlow lens which help but does loss the clarity and it is an expensive barlow, so i wouldn't buy one unless you really need the extra size. That being said the lens itself is one of the sharpest i have and is very comfortable on the eyes. Don't forget to use a good quality moon filter as you will need it with the lens to protect your eyes, stay safe and hope you have some wonderful clear skies.

Celestron luminos 10mm eyepiece. Build quality is excellent. Good weight to this and has a rubber hand grip. It has a nice feature where an eyecup is hidden and a twist of the barrel and out it comes great idea. I was a little disappointed that it did not come with a storage case at the price it is. Nice lens cap for protection. Would recommend this to the serious astronomer.

Purchased this EP from Amazon , it arrived and had clearly been used before which wasn't a good start . Amazon accepted this and gave a discount that I accepted . Now ,onto the EP . It's big , no , it's huge and it weighs 1.3 kgs !!! Please make sure your scope can cope with this weight as I'm sure balance will be a problem for some . Build quality is excellent with a big rubber ring around the centre which doubles as the twist up mechanism for the eyecup . I had to extend the eyecup to its fullest to have the best views . Now onto the view . I found them to be excellent, on the whole but at the edges the field of view seemed to brighten somewhat which was a bit off-putting . Also the view didn't seem entirely flat . Having said that , the viewing area was breathtaking and the 82 degrees of viewing angle is fantastic. I used this EP in my Nexstar 8se.

Excellent and high quality eyepiece. I bought the Celestron HD Edge 11 inch and the eyepiece you're provided with is rather generic and not good for planetary details (although great for viewing the moon.) This 10mm is much better

Just meh, I thought it would be a great piece to have. But it’s really average considering it’s nearly a 300 euro piece.

I had head that an expensive eye piece would make all the difference to my viewing - but did not really believe it until I bought this EP - clarity is so much better than the standard EP's - can clearly see the bands and some of the turbulence. Bode's nebula clearly visible. This was using an 8" SCT scope. I am looking forward to the winter months when I will really be able to test it's quality. Might be asking santa for the 32mm EP...

The 23mm Luminos is at the top end MASSIVE weighing in at 1.1kg, make sure your focuser can lift it Nice field of view, not TV but for the price, amazingly good Remember this Luminos is not for the faint hearted, its big and heavy In the league of Terminagler, Enjoy :)

This eyepiece is a superb complement to my 6se. A forgiving scope, as far as eye pieces go, nonetheless, this is an excellent match for my orange tube. I've been able to compare the 15mm Luminos against the less expensive stock piece (25mm), the starter kit I have (6, 8, 13, 17, 32 mm) as well as a more expensive ES 20mm. This is currently my favourite eyepiece both for magnification and field of view. And the views are crisp with no noticeable distortion from edge to edge. Good eye relief too. The Luminos 15mm is a very nice eye piece for the money. I can't say how well it works with a faster scope but for my f/10, SCT this is an excellent choice. I've since ordered the 7mm and I'll probably buy the 10mm too.

super

Después de mucho investigar y pedir consejo, finalmente decidí adquirir este ocular en lugar del ES de la serie 82º de 6.7 mm. No me equivoqué. El ocular me llegó en solo dos días y en perfecto estado. Luego de revisarlo con mucha paciencia, no encontré ninguna partícula extraña en el interior de la óptica, ni arañazos en algún lente o manchas internas. Los recubrimientos se ven oscuros y con tintes verdes o púrpura, según el ángulo de la luz y totalmente uniformes. Gran calidad de construcción. Solo he tenido oportunidad de probarlo en dos sesiones, pero ha sido suficiente. Todas las preocupaciones que tenía al respecto han sido borradas, te comparto algunos detalles: - Es pesado. Si tu telescopio tiene un enfocador de plástico muy endeble, es probable que sufra para moverlo con facilidad. Yo lo estoy usando en dos tubos medianos sin problemas. (6" y 8") - El "eyecup" (el protector retráctil) es por mucho, el mejor y más cómodo que he utilizado en un ocular. Te permite ajustar por completo la distancia al ojo dependiendo de tu configuración facial, y evitar por completo los posibles "blackouts." Yo soy MUY sensible a las aberraciones de la pupila de salida y en general a los blackouts; este es el primer ocular que puedo usar sin problemas desde el primer momento. Esta era mi principal preocupación. - El campo de vision de 82º es una delicia. Este es mi primer ocular de campo ultra amplio. Hasta ahora, el de mayor campo que tenía es un UFF de 65º y la diferencia es enorme. Te puedes "asomar" por los bordes y sigues teniendo campo disponible. De hecho no se ven los bordes si centras tu vista y dejas que tu visión periférica los busque. Es una delicia. Es una experiencia que es un poco dificil de describir... tienes que verlo con tus propios ojos. - Al ser 7 lentes, la corrección en los bordes es muy, muy buena. El astigmatismo es prácticamente nulo y tienes que ir a buscarlo hasta el extremo del campo de visión y aparece muy tenue solo en el extremo. - Y bueno, también al contar con 7 lentes, es ligeramente menos brillante que un ocular con menos lentes, pero maneja mucho mejor la dispersión de luz (obtienes mejor puntualidad en las estrellas) y el contraste es MUY superior a un diseño óptico con menos lentes. Al menos comparado con mis goldlines, plossls, kellners y zooms económicos. - Es una focal corta. Si tienes un telescopio con mas de 800-900 mm de distancia focal, este ocular producirá un aumento considerable, que solo resultaría util para planetas o nebulosas muy pequeñas. En mi caso, lo estoy usando con focales de 750mm y 800mm y me da un aumento de 113x y 121x (en realidad su distancia focal es de 6.6mm) y para mi son los aumentos que más uso para observación de cielo profundo, de objetos compactos. Si tienes un MAK o un SCT, este ocular seguramente entregará demasiado aumento que podría ser poco util en noches de cielos mediocres. En general estoy MUY satisfecho con esta compra y si estás considerando un ocular de campo ultra amplio en esta focal (7mm) no lo dudes. Te lo recomiendo al 100%. Salud y cielos claros!

Very well built and has a good weight to it. I have yet to try out extensively but from the couple of times of usage, the optics are clear and bright. Excellent quality at this price point.
