I do not like the new eye-ring that consumes some of the eye-relief.
まず、このアイリングはアイレレーフを消費していて、改悪だと思った。
But, later found it was replaceable.
でも、簡単に取り外せることが分かった。
The field stop is as large as 47mm as before.
視野環径は以前の通り、47mm。スペック表示の85度は相変わらず??ですが、(正のアイピースとしては)2インチバレルで最大限の実視界を確保していることには間違いありません。(見かけ視界の上げ底表記はほぼ全メーカーがやっているので、仕方ないでしょう。)
低倍広角用として、非常に抜けの良い快適なアイピースだと私は思いますが、視野周辺までの点像等を最重視する方はまた違う選択肢があるかも知れません。ただ、双眼使用では、目幅によって外径の制約がありますし、このコンパクトな32mmは少なくともBINO用の低倍用アイピースとしてお勧めできると思っています。
Makers seem to be well aware that the more FOV display will promise the more sales.
It is very like actors or singers fudging on their height for their popularities. But I think they never fudge by inches, for fear of the fudge to be exposed, while there seems to be so many eye-pieces in the market as too much FOV displayed in the specs.
Local armwestling tournament, open category, was held last night in Tottori City. Most of the competitiors seemed to be near local, but several experts came all the way from Sakaiminato City,far west of Tottori Prefecture.(Tottori-City is located far east.)
I entered in the Beginner’s Section, but “Beginner” really didn’t mean a beginner to the letter. Most of them were actually advanced persons and very strong. I could only get two wins, each one win on right and left respectively, on the consolation match. I was a bit dissapointed with the result, but at the same time I told myself it was a small one step of my Armwrestling carrier.
After party was held at the snack bar,”South Orange”, in charter, and I was very happy to join the local members and to be introduced to the experts. Armwrestling table was also brought in the bar and we enjoyed practice matches over a glass of beer.
Not only they were so strong but also they were so nice. There was a common value of a kind of “Investigator” in all of us, and found all of us are very serious in improving ourselves.
Finally, I completed the 4″ refractor FC-100DF binoscope assembly,
It’s a view of fantasy, nothing can be compared.
I took apart of it and taught my friend (the binoscope’s owner) how to assemble it by himself today, it took me half a day, much longer than my expectation, then I finally aware of something 🙂
let me share it with you…
People with some basic understanding or experience, only very basic is enough to learn quickly. but if people are lazy or hesitate to try or people with strong subjective (generally it’s wrong), they are really hard to learn new, they can not master binoscope well for sure.
However, I completed the “technical transfer” and my friend did adjustment pretty well at the end.
I have to thanks for your very good instruction in Web, and your great product.
Thanks

Comment by Matsumoto;
Thank you Ted for allowing me to introduce your e-mail report in my website.
Congratulations on your finishing the fine binoscope, and I am much appreciative of your effort in sharing your experience with your followers in your country.
The Altitude Sensor is set on the center of the base plate in the first photo.
The Sensor, I have developed with my friend, includes WIFI system; and it offers the perfect PushTo System with SkySafari on iPhon or iPad.
この傾斜センサーは、私(ケース加工担当)と友人(電子回路担当)の手作りで対応しており、生産台数が少ないために積極的に宣伝して来ませんでしたが、このご投稿のように、将来に向けても、大きな可能性を秘めたシステムです。当初は、NEXUS等のWIFIアダプターと併用するものでしたが、AAS-2以降、そのWIFI機能まで包含し、単体で水平軸エンコーダと併用することで、SkySafari(Pro or Plus)が使用できる仕様となっています。
