呵呵,终于坐到了沙发.又有毒品上来呀.

這鏡頭可以說是全球80mm折射鏡的最高水平之作，一般兩片空氣頭，可以造到影像很銳，但色差修正度不足，三片式修正了色差，郤因為鏡片校正水平不足而柔化了影像，這些例子多不勝數了，我們最近數次小組室內星點測試也有所體驗。

LOMO、LZOS的工藝正在這方面體現，我的203APO能夠造到f7這麼大光圈而又能推上500、600倍實效觀測，便是一例。

剛好這台鏡又很容易配到合適的平場鏡，TS2平場鏡、SkyWatcher 0.85x平場減焦鏡等便是。

因為這鏡很難找到了，有興趣要趁早下手。

xiaoer & I test this lens intensively. What I can say is that with proper back focus adjustment, most flatteners can work with it in full film DSLR. e.g. TS2, AstroTech, Borg 7887, SW etc...

其實這鏡的真正威力，應是在星點測試上吧?

至少我們至今尚沒有找到一台星點表現比它好的鏡，同意吧?

當然一台頂級目視鏡，若花千多兩千多元配個平場鏡可以拍全片幅深空的話，還是比較合理的。

題外話，上一張APM-TMB 105/650 配 36x36mm片幅的16803晶片拍的M45，這照片無論曝光及後期處理都沒怎麼樣，但我比較關注是其像場修正度，例如四邊及角上的星點銳利度。

可按照片左下角download圖片檢視，我特別留意，超135全片幅的範圍外，星像也沒有缺角星芒的問題。

社長，
這明引我姐！ 那個 Focuser 換 Feather Touch 要多少錢？

是否將來可更換 Feather Touch Focuser?
光軸已軸好嗎？
是否先前測試那個鏡頭？

死啦~~~ 原本已放棄的，又被你引起。破產啦~~~
唯有放棄 Skywatcher ED80

[社長]

誰告訴你我的80/600要調光軸?

我有兩個頭，你可以來做星點測試然後任挑一個。

但因為只有一枝鏡筒，而APM-LOMO 80/600不再生產了，所以我要訂一枝全新的William Optics Megrez鏡筒回來。

將來換Feather Touch? 按理應該可以的，但要看實物，我剛好手上有一個3.5" Feather Touch motor改2"的原厰adaptor，數百元而已，那你便可以跟130/780的互換了。

現在都有些人在問，若你確認的早點PM我。

[funoooo]

我要啦! 但要 Willis 測試那個鏡頭. 其他詳細就另談!

[社長]

Willis 是你的指定望遠鏡測試員?

我17日離開香港，要到馬來西亞組裝天文台，又要到寧波開會，之後到西藏拍星，最好這兩星期做了。

No! I just tested xiaoer's LOMO 80/600 not other. She bought the telescope & we tested our 80/480 & 80/600 together.

[社長]

我印象中你測試過我的80/600

[willis]

我印象中你測試過我的80/600

Yes! Star test & terrestrial observation for a short period of time, but not an extensive test as xiaoer's 80/600. My impression is excellent. Eagle eye!

[社長]

I am the 2nd owner of my 80/600, but the first owner never use it, so basically it's new. The first time you saw through my 80/600 was at Lake Egret Observatory, with a TMB Aspheric Orthoscopic 25mm eyepiece, I guess this eyepiece may sell for US800+ at 2nd hand market. Then we did artificial star test at my old office at 3/f.

on a very clear Summer night last year, I pushed up to 270x with TMB Supermonocentric 4mm eyepiece + 1.8x ED Barlow, and the lunar image is still solid, even at this ridiculous high magnification. I won't use the term "never run out of power", but for premium APO refractor, the real power only show off above 2x per mm aperture. Well, just like your Italian sport car, only show off it's real character at over-speed.

The real value of a premium APO is, it give me a peace of mind, never interested in any 80mm refractor.....

My 203 f7 APO is not as well corrected as the f9 model, but it's very unique, you never find any APO made, no matter by Takahashi, Astrophysics, TEC.... being as short / portable as mine.

Is 203APO big? yes by typical amateur standard. But considering it's power, it's really as "small" as a Porsche.

哈哈哈，奴老闆有興趣要一支經御用試鏡師willis品質檢定的80/600，我唯有忍痛割愛！
拿，又試過晒Dflattener, reducer，又配置了feathertouch focuser，又係有型靚仔的碳纖筒，一次過滿足晒三個願望！
收返你一萬+幾千都值啦~

[社長]

我唯有忍痛割愛！

割愛? 妳想造雙筒?

小兒！ 上次我先已割愛給你啦。今次無理由同我爭播！

[社長]

男人不壞，女人不愛，小兒把有型靚仔割愛給你，或許心有所屬.... 是否一個壞孩子?

社長，

Willis 測試結果如何？
