I bought a ES 11mm based on the reviews that I was reading a couple of years ago. I wanted to see if the ES eyepieces were as good as people claimed. YES they are that good!!! The 11mm is considered the best of the series. As you can see from my sign line I've bought all of the ES 68° and 82° eyepieces. I have nothing bad to say about any of them. With 4 scopes they all have a place and are excellent for the money. It would cost some big $$$ to get a little more performance. With my age and eyesight I couldn't see spending that much money for the ultra premium eyepieces!!

I would take the 12mm XF over the 11mm ES82. I think the 12mm XF is one of those eyepieces that is significantly better than its reputation on this forum would suggest. Most of the criticism of the 12 XF is with regard to field curvature, but I have never found it to be as bad as the criticism would suggest. It is an incredibly sharp eyepiece with excellent pinpoint sharp star images, excellent lunar/planetary sharpness and it works extremely well with a barlow.

Hi to everyone.

Would any of you be a fan of the ES 82° 14mm instead of the 11mm for Mars, Jupiter and Saturn?

Absolutely! I consider the 14mm to be one of the finest of the ES82 line. I don't see any of the field curvature some people have reported. In fact, in my 12" f/5 newtonian with Paracorr (which gives a nearly completely flat, coma-free field), my 14mm ES82 is tack sharp right to the very edge, which means the eyepiece itself has a superbly flat field. However, some people have tested more than one 14mm ES82 and in some cases, there have been strong differences between samples! Some have strong field curvature, others, like mine, are completely flat and have superb performance. This will explain the very different reports from different people.

I bought mine in September and it has since become one of my most used eyepieces. Its lunar-planetary performance in my long-focus refractors is spectacular and it is a wonderful deep-sky eyepiece in my 12" dobsonian.

For strictly planetary observing in most telescopes, its focal length may be a little on the long side. In larger cassegrains it should be excellent.Clear skies!

I agree with Thomas, I find my 14mm to be the best of the line.

I also find no field curvature, it is very flat, I must have got lucky.

Closely following the 14 is the 4.7 in my set anyway.

I know it has nothing to do with the Nitrogen or Argon gases used but is it the earlier ES 14mm Nitrogen filled eyepiece that people claim to see field curvature?.

The 14mm ES 82 has it, the Meade 14mm 82* 5000 UWA has it, All of the 14mm ES 82's have it. Younger people see less of it, older ppl see a LOT more of it, (field curvature).

Not to hijack Mike's thread - how would the ES 6.7 82 compare to the Meade UWA 6.7 4000? I have the later but have been impressed with the ES 24 and 16 68.

I have them both, plus the 6.7mm. I use 8.8 as my highest power in my 8" SCT for 225x only on great seeing nights. If it's not to good seeing, I'll drop down to the 11mm.

The 6.7mm is used for highest power in my other smaller scopes.

Great EP's for the money!

Hi, Thomas.

Thanks for the answer.

How would you rate your 14mm and 11mm in short tube refractors?

I use the 4.7mm to collimate my C8 when the seeing is great (once or twice a year where I live).
Then the 6.7mm can be used for amazing views of Jupiter or Saturn or small planetary nebula or tight doubles. Don't be affraid to push it when the conditions are good.
Under average seeing, the 11mm is perfect in that scope (or for wider targets). The 11mm is very good, confortable and offers a crisp view.

On a very good transparent night, I used the 11mm in my 8"SCT on M13, it blew me away! Filled the entire FOV with averted vision.
