每次我們搞星空派對時，都會集中用兩款目鏡，TMB Supermonocentric及Televue Ethos，間中也會用上Binoviewer。

上週的星空派對我們談起，下次大家可以把手上的Ethos拿出來組合成雙目，用Binoviewer觀測。讓我粗略數一下大家的Ethos，如有遺漏請更正....

社長：Ethos 21, 17, 13, 8, Baader Mark V Binoviewer
David : Ethos 13, 6, 3.7, Denk II Binoviewer
Willis : Ethos 3.7
Xiaoer : Ethos 3.7, Sky Watcher OEM Binoviewer
benben88 : Ethos 8
Sharkfin : Ethos 10

即目前可以併起來的就是Ethos 3.7、８、13

Benben88 : Ethos 8 & Baader Planetarium Maxbright Telescope Binocular Viewer

Willis: Ethos 3.7mm, 6mm, 10mm, Sky Watcher OEM Binoviewer

Ben,
How's the performance of this Baader Bino? The price is good!

David : Ethos 13, 6, 3.7, Denk II Binoviewer

Willis : Ethos 3.7, 6, 10, Sky Watcher OEM Binoviewer

Xiaoer : Ethos 3.7, Sky Watcher OEM Binoviewer

benben88 : Ethos 8, Baader Maxbright Binoviewer

Sharkfin : Ethos 10

原來數漏了，那我們可以做Ethos 3.7, 6, 8, 10, 13 雙目了。

17及21是2"的，雙目不了，亦好像17比較尷尬，21回來後便沒怎樣用過。唯一是David的18"UC好像和Ethos 21不合焦　

每次这么多宝贝，是否需各人贴上标签，以示识别，避免混淆…

xiaoer : Ethos 3.7, 8, 13, Sky Watcher OEM Binoviewer
唉，嚴重重複了，早知不用買啦~

Here are the counts so far:

Ethos 21: 1
Ethos 17: 1
Ethos 13: 3
Ethos 10: 2
Ethos 8: 3
Ethos 6: 2
Ethos 3.7: 3

We overbought. Oh dear....

Willis ,

I didn't try side by side test with other binoviewers but I am satisfy with its performance . Maybe next time organise a test for the various binoviewers ...

17及21是2"的，雙目不了，亦好像17比較尷尬，21回來後便沒怎樣用過。唯一是David的18"UC好像和Ethos 21不合焦　

I looked through the above combination and it did reach focus and I think it is something to do with the coma of the 18 UC , paracorr type 2 should make most of the stars in the field sharp.....

David brought a Paracorr type 2 right after he got the 18" UC, but we never bother to use that.

no need to test, mine Baader Mark V is rated the pinnacle of binoviewers on Cloudynights. no need to test, no, no, no, no..........

很簡單，通常那一堆Ethos中，成色最好的就是我的。

David的目鏡通常在地上滾來滾去的

But Mark V's price is at zenith too. According to opt's info, the Maxbright verision is the China OEM of Mark V.

So maybe worth to try....

so we over-accumulated Ethos eyepieces, may be we should shift residual purchase power to Nikon NAV HW Eyepieces? Anyone want to try?

so Willis why not order one for testing?

Ha Ha! Benben got one. Try his bino next time.

剛才帶了三個新玩具去曬雲來雲去中的月光光。80/600 + 3.7 mm的感覺最特別，就像...就像"食波餅"！可以看到FULL DISK的，但眼睛的視野7根本不能同時看到這麼闊，就像整個月球壓過來一樣，很好玩，不過實用性不高，反而用更長焦距的鏡子放更大來看細節可能幾好玩~ 8 mm可以同時看到整個月亮有多，即是未用盡眼睛的視野，我想6 mm應該剛剛好，有機會找你們交換個試試看。 期待帶它們去曬太陽和看deep sky~
另外，我知道8 mm和13 mm的那口screw有什麼用了。剛才上1.25"的barlow，真的要用那口screw才上得實啊！
