Re: 誠徵43mmep holder adaptor

AFAIK, for commercial products, you may ask the vixen dealers to sell you a 43 - 36.4mm ring and a 36.4- 31.5mm eyepiece holder. ( I interpret your request as : telescope draw tube 43mm thread - holder as requested - ep ) of course, you may directly buy the 43mm camera adaptor and use the front sect...

上個星期日去咗東霸玩guide 星, 用m8 + f/6.3 reducer + 300d ( 合成焦距 : 200mm*1.6*6.3 =2016mm), 係五分鐘時段內共按RA鈕修正約十多下. GUIDING並不困難. 電方面, 整舊12V 3A LEAD ACID便可玩半晚,當然,玩GOTO多D , 電就少D, 12V9A 就保證你全晚點goto都得(SS2k + gpdx, TOTAL PAYLOAD為M8+guide mount + C記80mm f/5 guidescope +GA4 + EOS 300D,共重 約18磅) ="LT"]嗯~~不過skymemo 既準確度較GP Mo...

一分錢一分貨, 試過一支代理自用的大陸五吋短焦折, 結果是土星環的清晰度比在下支四吋vixen ss100 差. 結果呢 ,代理自己都買番支ss100看門口

其實, 很多人都不知道vixen ss100( 及姊妹鏡ss80) 只不過是供中小學生用的入門鏡. 台灣同好陳培坤就著有一書, 講ss80 set up ( 坐井會藏有該書, 我就是從坐記看到的)

印象中, 網友BILLY 支鴨記五吋折便是刻上SKYWALKER 牌, 星期一SIDEWALK 時他便是用此鏡去推廣的. 諸位可有看過他的愛鏡?
