Astrocafe 優惠 - Sky Watcher AZ4 經緯台
發表於 : 2010-02-11, 20:21星河科研社剛引進一批Sky Watcher AZ4經緯台，並為Astrocafe會員提供優惠，數量有限，售完即止。有興趣會員需以Astrocafe登記電郵發至 admin@astrocafe.hk 訂購，售完即止。
AZ4經緯台堅固實用，可承托150口徑望遠鏡，配合大面積Telon軸承及阻力調節，可讓望遠鏡運轉流暢之餘，又能於微風環境下抑制振動，適合中低倍天文觀測。
此經緯台適合承載各中小口徑天文望遠鏡，作個人、小組天文觀測、推行路邊天文活動等。
原價 港幣1580 / 會員優惠 港幣1280
Now Serving Optics on the Rock. (Neither shaken nor stirred)
The AZ4 (the Rock) mount is a true rock-star. It performs like a champ dampening vibrations so they don't compromise your viewing. It will hold steady in a modest breeze, and won't "shake, rattle and roll" at the slightest touch like less capable mounts. The AZ4 manual mount is servable for small aperture telescopes up to 6", spotting scopes, cameras, video cameras. The AZ4 is perfect for serious Casual Observing. While the observing experience starts with consideration of an appropriate optical system, the telescope's optical mounting platform comes in a close second in importance.
The telescope's mount can make, or break the perceived quality of the viewing experience, regardless of the optical system chosen for use. The superbly designed Sky-Watcher AZ4 mount is remarkably portable with heavy-duty, yet relatively lightweight construction - a veritable paragon of stability - perfect for demanding terrestrial and astronomical applications.
A mount's stability and ease-of-operation during the process of viewing stationary terrestrial or moving sky objects can make the experience a consistently enjoyable pastime, or render it perhaps momentarily brilliant, but generally frustrating as images appear to dance around uncontrollably in the eyepiece in a breeze, or at the slightest touch. Mechanical stability and fluid tracking are the keys to mount quality.
The high-performance Sky-Watcher AZ4 mount excels admirably in both these important attributes. The Sky-Watcher AZ4 pan-handle mechanical tracking motions about both axes glide on large thrust-bearing surfaces lubricated by industrial-standard Teflon bearings producing smooth, fluid motion. Control knobs adjust the mount of drag (stricture) to ensure ease of movement without loss of precision.
The mount and tripod head are constructed of rigid, cast aluminum. The tripod are sturdy, light-weight aluminum (AZ4-LJ1). The AZ4's altazimuth design also adds to the mount's stability as the center of gravity is directly over the tripod.
