Sightron nano tracker 攝星儀
我都忍不住就去買了壹個 Sightron nano tracker 攝星儀。
人有我有，我喜歡佢體積極之細小及輕，我相信佢係目前可以買到最細小及最輕的攝星儀 ，放在手掌上就見到佢幾細小， size = 98 mm x 60 mm x 44 mm，weight = 400 gram。

Sightron nano tracker 攝星儀，
佢本來那個對極軸的小孔不好用，我將壹枝國産極軸鏡改造了個座裝上去。
又將壹個舊款的 “哈雷”微調雲台加壹件鋁角改給23.5 度北緯使用但仍可再作微調給其他緯度用，裝上輕便相機三脚架 (Velbon 640)。
要等好天拿出去試下先，這是壹套十分便攜的星野拍攝裝備。
﹣﹣﹣﹣
外國有天文同好將 Borg 折射鏡連 Borg 有微動經緯儀裝上 Sightron nano tracker 攝星儀作為超迷你的便攜目視觀星裝備。
全套可以放入一個小背包，到郊外可以拍攝星野及進行一些目視觀測。
