Well my E.S. 9mm 100º eyepiece is shipping today. I really wasn't sure about getting this eyepiece. I even canceled my original order to give me another week to think about it. So today I called Astronomics had a short discussion about the 9mm then put my order in. So they said the eyepiece which is now in stock will ship today. Really hoping I like this eyepiece.

Well, judging by your sigline, you'll be using it in entirely different scope size/types than i do, but in my Dob the ES9-100 is a total killer! The FoV is immense, tho quite usable IMHO, and the quality is nearly Ortho-like! When i've viewed planets with it, it is only *slightly* edged out:
1) IF i replace it with a 10mm CZJ Ortho, and
2) IF the seeing conditions are quite good!

If there's one aspect that ain't quite perfect it's the eye-relief; with wearing eyeglasses i can just comfortably see the full field of my 13mm Ethos (rated at 15mm ER), whereas the 12.5mm ER rating of the ES9 is about right, and i can't quite get the full 100 with eyeglasses... tho prob'ly 90 of 'em. A minor nit, really.

Optically i'm VERY pleased with this EP!
Here's hopin' you are, too!

Please keep us posted once it arrives, and you've tried it a bit.
:grin:

I do recommend if you use eyeglasses stay away from ES100 (9mm to 20mm - the 5.5 and 25mm versions I hope will have better useful eye-relief) or Ethos SX. With my Ethos 17 I can see 82 to 95% of the field of view (with and without rubber eyeguard, respectively), as opposite to <50% on an Ethos SX3.7 or an ES100 14mm... :bawling:
But I also mainly use these during day light and ER is even more important...

I was at an outreach event Saturday night and used nothing but 100° eyepieces (ES & Ethos). I asked everyone who wore glasses to remove them and focus for their eye. No one had any problem viewing with these eyepieces (over a dozen with glasses).

I can see where it might be problematic for folks with significant astigmatism, though.

HOLY SMOKES this is a big eyepiece!!!!!!!!!! :bigshock: :bigshock: I haven't owned an eyepiece this big since I sold my 20mm Nagler typ2. I am going to have to go back to using a TV Equalizer with my lighter eyepieces. Here is a picture of the eyepiece loaded onto my car!! Mike :jump: :jump: :jump: :jump: :jump: :jump:

Thank you...the TV Equalizer is just what I was looking for to help balance my (relatively) diminutive ES 6.7 with the bigger 9mm and 14mm 100° eyepieces.

And yes, the 9mm is a very nice eyepiece.

When I bought the ES 9mm 100º Series eyepiece I thought it was big! Now that my ES 30mm 82º Series has been delivered I know what a BIG eyepieces looks like!!!!!!! Here is a picture of the 9mm, and 30mm together. All I can think to say is WOW. :bigshock: :bigshock: :bigshock: :bigshock: :bigshock: :bugeyes: :bugeyes: :bugeyes: :scared: :scared: :scared: :scared: :scared: :scared: :scared: :crazyeyes: :crazyeyes: :crazyeyes: :crazyeyes: :crazyeyes: :crazyeyes: :crazyeyes: :twitch: :twitch: :twitch:

I forgot to mention this eyepiece is a N.O.S. item that I purchased from Woodland Hills Camera, and Telescope for $189 with free shipping.

I am thinking of picking up the 9 myself. I already have the 14 and the 20 along with the 30N2 82. The 9 would replace my ES 8.8 82. The only question is where to buy it. Astronomics has the CN discount. Agena has free shipping plus they throw in a plastic bolt case. Decisions, decisions.

I'd been thinking about the 11mm 82 but no one has shown it in stock in months. So now, I'm thinking this one sometime in January. Too much for an 8" Orion Dob? I've been getting great views of Jupiter with the 5mm stratus so I'm thinking this would work pretty well to fill the gap.

Or should I save it for a 16" LightBridge?? Ah, decisions!!

The ES100 9mm is nice... Barlows well too (GSO 2x ED barlow) and works well with only the bottom element of that barlow as well, giving you ~6mm (1.5x).

Garsh, Mike... i don't wanna say that 30mm EP is big... but with its cap on it could double as an equipment table at your observing site.

I have the Zhumell version of the GSO Barlow. I should just screw that into my 14 ES which would give me about the same mag and field as the 9. I have done that before with the 14.
