Celestron 93317 Omni oculair, Omni Serie - 6 mm

I know that this isn't the best plossl eyepiece on the planet (i bought the 12mm) but it is LEAPS AND BOUNDS better than the stock eyepieces that came with my scope (Celestron Astromaster 130eq). I plan to slowly upgrade all of my eyepieces but dang, I love this one! The Omni line feels nice, like the build quality is good (i also have the 2x barlow). Overall, i'm quite pleased with my purchase.I took the attached photo by using a phone mount to the eyepiece (i have an iPhone XS), taking a short video and then using software to stack the images and remove noise. :)

Good value and quality

Oculaire célestron omnie 9 mm monté sur lunettes skywatcher 910 x 90.Possesseur de plusieurs oculaires deux fois le prix de ce 9 mm, ce dernier malgré un champ de vision légèrement restreint (mais suffisant) à de bien meilleur contraste et détails !!!!Impressionnant de précision pour la lune, et déjà largement suffisant pour planètes exemple détails sur Saturne: 4 bandes séparation tempête bien visible ainsi que la tempête "spirale" permanente, le tout malgré une observation avec pollution lumineuse grande ville...Bref pas la peine de dépenser plus !!!!😁👍

I got the 4mm eyepiece to use with a 114mm reflector with a FL of 500. At first I was skeptical, I read reviews and had many "experts" tell me it would provide too much magnification. I assume they saw 114mm and assumed the worst. This thing provides excellent magnification and produces a detailed image!Full Review:For people looking at this eyepiece there are 2 factors more important than the size of the primary mirror. The first is quality, I'm using an Orion telescope but there are other good brands out there. Is you are using a cheap barska or some other department store brand you are sadly wasting your time. The second most important thing is focal length. Based on my research the best a ground based telescope can do in magnification is about 300x simply due to the atmosphere. There are exceptions like remote locations and unusually calm atmospheric conditions but those will be rare occurrences. In my experience there will be times when atmospheric conditions won't let you see much detail at 100x, that's just the way it goes. Additionally if you want to get the best view of planets you want to wait until they are as directly above you as possible to minimize how much of the atmosphere you are looking through. So that said, to figure out a eyepieces magnification simply take your focal length and divide it by the size of the eyepiece. So (500/4 = 125x)... That is well below the scopes limit of 228x. You can figure out a reflectors limit by multiplying its size by 2 so (114 x 2 = 228). So the greater your FL the more magnification this will apply. This eyepiece will certainly give you more bang for your buck with a FL of 700 but it's still great on the lower ends and I recommend it. Knowing what I know now the only way to potentially do better is get a 5mm and a Barlow 2x, I have the latter.

Es gibt aber keine Box oder so, das Teil kommt halt in einem kleinen Pappkarton mit Schubdeckel. Aber beide Enden sind mit entsprechenden Kunststoffkappen geschützt. Das Okular hat auch ein inneres Feingewinde zur Aufnahme von Einschraubfiltern. Ich bin zufrieden :)
