7lbs and $1200 (roughly) 3" diagonal and focuser (much more money). I can't see doing this but, can you? Are you going to buy this eyepiece? If it is a dob, is your secondary large enough to illuminate this eyepiece? Are you going to increase the size of your CO to accommodate this giant? I think it could possibly be worth doing in one of those giant refractors like a 10" f15 or the like but, for the rest of us, I really think it is crazy.

Same here. No possible rationalizations :-(

I hear that Admiral Ackbar is going to buy two of them to binoview with.

Me too...my main reason would be that the increase of actual and apparent FOV compared to an already large FOV 31 Nagler is not very much, and to get that extra would cost a difference of $750 compared to the fairly easily available used/nearly like new price of a 31NT5 (which I bought new in the incredible Hayneedle + TeleVue sale a few years ago -I bought it new for nearly the same price as a used one).

I thought this was the response I would get. I did expect someone with a giant observatory mounted refractor to be excited about the prospect though. I am certain that I read at least one comment about someone looking forward to this eyepiece so maybe we'll get a yes or two later:-)

Other than a huge observatory scope, I would think that a large aperture refractor would be the best candidate for this, like the Stellarvue 160 mm Apo.

It comes with a 3.5" focuser and should be able to make use of the full field stop. And the cost of this EP is less disproportionate to the cost of the scope. Once you've bought the 160 mm Apo and suitable mount you've dropped $20 grand or so. What's another $1200?

Yes, I have preordered one for a large refractor. (The exit pupil is too big for my Newtonian)

Kudos to Explore for taking risks and pushing things a bit.

If they make it suitable for a big cat with no loss of light then never say never :D

Large refractor for the win.
I believe the large secondary makes this EP impossible for the scopes that would be the best customers for this. Because it would be great to have the extra fov in a large dob but, balance issues would be hard to deal with as well. The 25mm is probably the best we can hope for.

I am first in line to buy it, and I have reasons to believe this will be the very best eyepiece in the world available commercially.
This eyepiece will be perfect for any scope that meets four requirements: flat field, coma correction and good illumination at 52mm circle (eyepiece field stop), and f/5 or slower.
So, C11HD and C14HD meet all perfectly.
Any refractor with 3.5" focuser and focal length starting at 1200mm will meet all requirements perfectly.
Dobs will not comply until a larger coma corrector is available. In any case given the trend of dobs to go faster these days (f/3 to f/4), a 30mm focal length is not important. Large f/5 dobs may like it when large coma corrector is available.
I plan to go with a 24" f/3 in the future, but I will use a Ethos 17 there. Meanwhile, the 30/100 will be master of the 7" apo and C14HD.
That is it, as simple as that. I don't understand why people keep repeating this eyepiece has a very small target audience. I think they do not understand how many C11HD, C14HD, and >=6" refractors are out there, increasing every day. Of course a $1500 eyepiece does not need to sell as much as a $300 eyepiece.

I plan on buying it as soon as I can get a hybrid .965 to 3" diagonal for my 60mm refractor. :foreheadslap:

If I had a scope that could make use if this eyepiece, I would get it. I already want the 9MM 120* one.

Definitely NOT in the market for this......BUT I think it will find a home. 20 years ago no one would have believed a $500 100' would dind a home. Back a bit no one had a 2" focuser.

Once the EP is here I would bet it finds buyers and they will prompt other manufacturers to make scopes that will work with it. Just the same as years ago no one made F5 newts with 2" focusers.

For E is peobably more of a Formula 1 product, it gives them credibility to say "we are advanced, we are cool, we have the biggest and best etc etc' its pebably worth the development cash just to be able to put it on the shelf even if they never sold a single one.

Not me! I would buy 30mm 82 degree! ES100 30mm is 7 lbs is almost as heavy as my refractor! Diffcult for simple mount for balancing unless you stuck with just one eyepiece ES100 30mm! I perfer to use 3 eyepieces for the night!

A Ha! I knew all that astrophotography stuff couldn't keep you away from eyepieces forever Helder.

I would be interested in one as well. I'm hoping the have the prototype at NEAF in April.

I am inline for one. Over twice the field of a 31 Nagler Will give me about a degree in a 25 F5....... Its not cheap, Neither is the 3" feathertouch but you only go around once.... Part of the rationalization if there could ever be one is it gets me the field bang of the small fast scopes at 10% of the cost (that is until a 3" paracorr comes out).... do the calcs with a starmaster F3.7 and paracorr with a 31 nagler (and I still get to keep the ladder).... Big Dobs F4.5 and slower is the only place this thing makes sense.

If you plan to get a 24" f3 why wouldn't you want a 3" focuser and secondary to accomodate the ES100 30mm (you would get for your other scope)? It might save you from having to transport so many scopes.
