Lots of wide field EPs out there.

 

Any experience with this new addition:

Where does this one fit in the hierarchy?

 

Any good for binoviewing?

I'll have an APM 20mm 100 HDC by Friday, as soon as I get some good seeing I'll plug it in, though I've never used an EP with field larger than a Nagler.

I have the 20mm HDC and is a great eyepiece. It is not going anywhere from my case (= it's a keeper). If the 9mm has the same quality as the 20mm, it's another bargain. The HDCs are also considerably lighter than the other equivalent 100s.

The weight is a big issue, especially with binoviewing and a smaller scope.  Pull the EPs out and the scope wants to do a nose dive!

It gives an excellent wide, contrasty view, but the er trips me up. I'm to spoiled with delos,es92,xw,morph.

As for bino-viewing, heavy and awkward possibly. I have the william optic version, at least I can rest my forehead

on the edge eye part to keep my eye a close constant. Never would of attempt to bino view thru it.

I am coming to appreciate the solid twist up eye cups of the XW and Baader zoom. From the marketing photos the WO-100 look similar in design to the Baader zoom eyecup.

Bought the 9mm 100* over the ES 9mm 100*. Hope I made a good choice tongue2.gif

You did.  I did a correct comparison of these two eyepieces and they were close, but the 9mm XWA was a little better than the ES100 and more comfortable to use.  The 9mm XWA presented more like the Ethos than the 9mm ES100.

Lot's of entries - getting crowded.

 

This implies greater than normal profits, encouraging new suppliers and new entries where they expect to succeed.

 

When Televue started their niche market with their first Ethos; they could have kept it exclusive by either filing a patent or not setting prices/profit so high.  The more entries into a market ultimately brings prices/profit down as more are competing for sales.  For the customer competition is excellent, and I love 100+ AFOV!

It is excellent for the customer, but gets harder to 'pick' the right EP for ones own set-up.  Need reviews and postings from CN members and their experience at the EP in the field to help choose.

When you are the company making the investment in R & D, price and profit have to account for that upfront investment.  ES, and those that followed, had those costs and the required optical designer expertise taken care of by Tele Vue's investment and could undercut them.  Take for example the ES 92 series.  These are currently a unique design of HW eyepieces, and ES is charging its customers for that R & D, i.e., no free ride.

Most firms attempt to maximize Total Revenue = Price x Quantity, and they know quantity will increase as they decrease price, or vice versa.  When ES entered the market they chose to undercut TV with what seemed like never ending continous sales.

 

ES now has a niche market in 92 AFOV, and TV has a niche market in long eye relief and Dioptrix correction.

I don't mind if it is crowdy or not in the (ultra) wide ep department. I stick with my XW's  cool.gif
