Celestron EdgeHD Schmidt telescope 迎春推廣

文章 BossKwan » 週二 17 2月, 2015 20:22

剛到新貨,迎春推廣。

論壇朋友對Celestron的EdgeHD鏡還好像比較陌生,現介紹下,兼來次破例超優惠推廣(低過美國零售價,只限論壇會員)

C8 EdgeHD OTA 鏡筒:HK$ 9,900- (只售兩套,只限論壇會員及限期至二月底。)

摘錄部份資料:
- For astroimaging, the EdgeHD optics produce aberration-free images across your favorite CCD or DSLR camera. All EdgeHD optics are designed to produce an extremely flat focal plane precise enough to match the strict tolerances of the largest commercial ccd detectors, allowing all stars to be in tight focus to the very edge of the chip.

- EdgeHD optics not only produce diffraction limited stars on axis, but maintain diffraction limited stars across the entire field of view of many of the most popular astrophotography cameras. Even at the very edge of a DX format camera chip, the EdgeHD 8" delivers star sizes of less than 1.5 arc seconds.
