Luminos 7mm 1.25" Eyepiece for High-Power Planetary Viewing | High-Power Moon & Planet Views, 82° Ultra-Wide FOV, Twist-Up Eyecup, Fully Multi-Coated Optics, Retractable Rubber Eyeguard

I PURCHASED THE 7mm, 10mm, 15mm And i use them with 2 different Newtonian Telescopes: I was Gifted a Celestron 76mm Newtonian Telescope by my Wife, and it came with 2 Celestron Plossl EyePieces 10 & 20mm... Passion took over and shortly after i got my hands on another Newtonian Telescope, 150mm that came with a 25mm Kellner Eyepiece. STARGAZING LIFE CHANGING MOMENT: My Brother gifted me a LUMINOS 10mm EyePiece and i got hooked! These EyePieces give you a really wide field of view and rise brightness to another level. My 2 Telescopes have 700mm and 750mm Focal Lenght, so very similar, but they are very different in Diameter, Double to be precise, so one is an F10 and the other is an F5, yet these EyePieces made me see the sky a whole other way with both! Some people complain that the Luminos are affected by Edge Of Field Brightness, but i noticed a bit of that only when i am in areas with Blue Light Pollution... I'd say it's a professional Defect: these EyePieces are all about Bringing Luminosity to your Eye, and that's exactly what they do. If i am in a darker area, i don't see any Bright Ring around my Focal View and the views are beyond Fantastic, they really opened up the Sky for me. As the name suggest, these LUMINOS Eyepieces bring out the Luminescence of the sky; so beware if you try watching the Moon... You may need SunGlasses. ... Well, better use a proper filter. The Eye Releif is very comfortable, i can easily move my head around a bit, and still see the object i am observing, which is quite a great feature since far Planets tend to move very quickly. I should note I don't have an Electronic Mount, so i have to manually re-adjust the Tripod periodically... with the other Eye pieces i had to do it every few seconds, with these LUMINOS i get a couple of mins of good view before i have to re-adjust... quite a nice trait. The adjustable EyeCups make it easy to re-find the proper head position after each re-adjustment, and i find it a comfy feature. But BEWARE: these EyePieces are HEAVY, very HEAVY, so you will need to adjust the DoveTail to compensate for it, or maybe you'll have to put other CounterWeights, especially if you are using a Barlow too. With the Wide Field, i can place Jupiter, or Saturn in the edge of the view, and it takes a good couple of minutes, or even more, before it crosses over the whole Field of View, giving me all rhe time needed to focus and get a good view if the passing object. There is a slight Aberration towards the edge view when i use it with my 150mm F5 Telescope, but it didn't borher me, and to be fair: I corrected that by applying a 2X Barlow Lens. And man! at that point you might as well be walking on the Moon. I loved the LUMINOS 10mm so much, that i ended up buying the 15mm and later on even the 7mm, so now i have all the 3 LUMINOS Eyepieces in the 1,25" Barrel size. These EyePieces are a bit Expensive, yet so far i found them to be worth the investment and i am enjoying them a whole lot. Do not expect the view quality of a higher priced eye piece like a Pentax or a Televue... but we are talking about completely different price ranges. I believe in this Mid Price Range, this is the best you can find. Make sure you buy a good case for them, they come only with a Foamy Box and it doesn't hold them very tight, so you will need a proper case to keep em safe... I bought myself a case where i could safely put them together (in picture) I hope you'll find this Helpful

This is a great Eyepiece. On my ZWO ff107 I get 107x magnification. Price was very good.

Great upgrade from what I had before which were eyepieces that were included with my telescope. Images through this eyepiece are really clear and the wider field of view is amazing! It is a great purchase for the price. I highly recommend this eyepiece as an upgrade.

This is a good high-powered eyepiece. Whether in my 10" Dobsonian (where it gives 171x mag, and true field of view ["TFOV"] of 0.35 degrees), or my 90 mm refractor (where it gives 94x mag and a TFOV of 0.63 degrees), views are crisp and clear, and the 82 degree apparent FOV gives an immersive feeling. Jupiter and its four Galilean moons look especially great in this eyepiece. Recommended - although this is not ESSENTIAL, since a Plossl eyepiece of similar focal length would be sufficient, why not upgrade to this if you can afford a few extra bucks?

Sorry for the pun, but it's true. The FOV is incredible. It's so nice to get that magnification, and not have to constantly adjust to keep the target in the sights for more than a few tics. Clarity is good, and if it's a smidge darker, that's not a bad thing in my location because things are so bright I usually need a filter or put the cap on my reflector. I will say that I have to sit down to use this. For some reason, when viewing, it seems like the scope is tipping, or I'm falling over? Neither of which is true, but it's strange sensation. Update: I've loved the 7mm so much in my 750 f/5 Skywatcher, nothing compares, and I've tried, so I completed the set with the 10 and the 15 and with these three I'm sure to get a great view of planets and moon items.

This eyepiece is incredible! Its views are definitely on par if not better than my tele view ep that costs twice as much. I wish they made this in a 4-5 matthaglund but I combine it with a Celestron 2x Barlow and the images are still very bright and clear. Definitely an excellent ep for the money

For most (the casual user), and especially the beginner, this Celestron Luminos series eyepiece is what you should use (for under $100.00)! It is of much higher quality than the lesser eyepieces, that usually accompany a new telescope. Plus besides the higher quality lenses they use, the Luminos series has spectacular eye relief, and has a much wider AFOV, (apparent field of view of "82" degrees). With your new telescope, most all manufacturers will include 1 to 2 eyepieces, usually of lower quality, and most always at or near 52 degrees, to 56 degrees, AFOV. These are as easy as any made, to use, regarding the adjustable eye relief. They are an excellent choice, until you've decided to commit to much higher quality equipment (and have become highly proficient with telescopes), such as a large Dobsonian telescope, smart/computer controlled telescopes, and then the much higher priced "Explore Scientific", or "Televue" eyepieces. For me, being a casual user, the Luminos eyepieces are as much as I need, and have found them to be Celestrons best eyepiece, for the money. I really do love these! High quality and affordable!

This is an excellent eyepiece for planetary observations. The FOV is very wide, as advertised, which is also really helpful. On a clear night, I was able to use this with a 8" 1200mm Dobsonian, (effective magnification about 171x), and Saturn and Jupiter with its 4 Galilean Moons were very clearly visible. You can buy one of the green brand eyepieces, and it may be somewhat better, but they cost more than 2x

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.

lo compre junto a un telescopio sky watcher evostar 120/1000 para sustituir el ocular de muy baja calidad plossl de 10mm que trae de serie el telescopio para asi probar si la calidad de este telescopio con un ocular de categoría iva a verse con bastante nitidez.probe le telescopio y con el plossl se veía bastante niebla en toda la imagen y al cambiarle a este ocular celestron se veía aun peor no me lo podía creer pero asi fue.asi que todo el conjunto lo devolví

High quality product and crisp optics. I love it!

Muy buena calidad por el precio que se paga
