Re: 特別天文儀器用戶聚會:美國 Celestron 星特朗

Dear Tommy, Thanks for arranging such seiminar & gathering right after HKSM's afternoon talk. Early bird for me, 1 person. Q to Celestron : Why it takes so long for C9.25 EdgeHD to develop a dedicated 0.7X reducer and whether such reducer will be developed at all and if yes how long ? Raymond Tse 28...
