我原先想過買lightbridge 16'',但實在不能接受它的重量,而且又沒有David 寫:Yes, it is about 65 pounds. That's why, if you don't make your own scope, 15"UC and 18"UC are the next lightest dobs beyond 12" lightbridge.WFPC2 寫: UC15'' ,都應該仲輕過Skywatcher 或lightbridge 12''
12''和16''之間的尺吋...
15'' UC 是最合適的選擇,可惜價錢太貴,除非日後香港或國內有二首的
UC 鏡。
