是南極嗎?

從logo、調焦筒等看是了。

Sky Watcher的母公司叫Synta，數年前已收購了美國Celestron、歐洲Acuter，也為Orion等貼牌生產，據講已是全球最大的望遠鏡生產商，我也每年到總部一兩次。另外去年初金融風曝時也有幾間世界級的望遠鏡生產及天文儀器銷售商拍門求售，都被Synta婉拒了。她現時沒有出品最頂級的光學，但有點像Toyota吧，從入門至中高檔產品，服務了大多數愛好者的需求，你在Cloudynights上可以看到EON 120、ED120等的評價，而Maksutov的水平也備受稱道。

ED Pro系列有藍色和金色筒版本。雖說Equinox系列用上了德國Schott玻璃(Zeiss Foundation的公司)，但已被其更短的F6.25焦比抵消了一些威力，所以不計造工問題，其實目視上兩者應相若的。其實上次星點測試時也拿了一台80ED Pro出來，我個人看沒有明顯分別，或許Willis可以補充一下。

我唯一担心是調焦旋鈕上那圈橡膠圈，若我要投訴的就是經常遇上極端天氣時會斷掉　

Yes! We also tested the 80ED Pro. We cannot tell the difference, which means the difference is very small. I guess if we really want to tell the difference accurately, we need to set two mounts and do a side by side comparison. The point Xiaoer bought the Equinox 80ED is because Equinox got a dual speed focuser and the finish is more beautiful!

這亦是為何我到今天還供應這個型號，實際上有不少同戶忽略了一幾點....

1. 這台鏡可以配Sky Watcher原厰平場減焦鏡，合成焦距跟Equinox 80一樣
2. 作長時間曝光時，其調焦筒以及抱箍其實很穏固，我甚至認為比Equinox更適合
3. 目視上我不認為比Equinox看得出實質分別

當然，Equinox系列的造工的確勝一籌，而雙速調焦也很順滑，而Equinox在外國可說是備受讚賞的。
