Lunt 確認12月出貨,貨運資料:187 x 66 x 74cm,總重 41kg。

剛收到客戶通知,要求我們參與驗收,屆時用Paramount 或 Skywatcher EQ8架起來拍些照片吧。

為了答謝David你的幫忙,我會確保下月西藏星空派對時,你每天會不少於8小時的充足氧氣供應,晚間睡覺時室温比外面氣温高15度以上 :mrgreen:

作為 150 > 230 的潛在升(星)級客戶,歡迎歡迎 :mrgreen:

不過到時容許測試的日子不多,因為要馬上交給客戶,到時真的要你遷就一下時間了。

看過LS160F後你會知道跟LS152T不在同一層次上:

The photo is not taken by LS230Ha/T but a modified PST of 1A bandwidth only through a 230mm F11.2 (Ha wavelength optimised) DIY scope.
This demonstrates the very exceptional & surprisingly good quality of PST under high magnification.

According to this imager from South France with very good seeing , many photos taken by modified PST even surpass the new released
Quark 0.5A Ha eye-piece using the same setup.

This makes a hard choice between the mature product slightly cheaper PST (1A) and the good spec newly developed Quark (below 0.5A) Ha EP.

Raymond 你應該也留意一下新出的Lunt LS50T的後模組,也是PT的。

LS35T在外國稱為PST Killer,那Lunt的PT後模組.... ;)

邏輯上,Andy Lunt及其老爸David Lunt十多年前創立Coronado,後來賣給Meade,後來David Lunt過身了,Andy Lunt 在2008引入APM的德國技術(部份東西是Philipp Keller設計了,他也是世界各地一些米級科研鏡的設計者,以及ASA的靈魂人物),以及NEAF主席做股東,這幾年你也看到Lunt在技術上的發展了。

Dear Savio,

Any link or photo of this
"Lunt LS50T的後模組" ?

To take advantage of the maximum aperture benefit of the front objective, usual PST modification at the rear would involve a F10 converging light beam system.

Not sure whether LS50T use a parallel beam or converging beam.

按 Andy Lunt的說法,就算是鏡前濾鏡,接受的入射光線也不是平衡光線,因為太陽本身也是有面積的,所以重點是Sweet spot有多大。

除了ERF外,另一構思方向是用無鍍膜的反射鏡,但涉及大多我未試過的細節,下刪5000字..... :roll:
