This is a private sale! Before I come to the actual offer, let me explain first why I have to sell this telescope even it hurts me a lot that I have to sell it. I own this telescope now for 4 years and it was simply perfect for taking pictures with my Canon 600D, especially after I made some tuning. (some pictures you can see attached) Last year I had an accident which caused a dislocated shoulder and splittered several bones. Now I have a plate in my shoulder which makes it impossible for me to lift the telescope or even try to balance, it is just too heavy for me and is very painful. 會員名稱: 洪湯姆 名稱:GSO RC10/F8-ALUMINIUM-OTA天文望遠鏡 賣價:45,000 NTD (三吋線性滑軌條焦座) 賣品所在地:基隆市, 台北市, 新北市 賣品起止時間: 賣出為止 交貨方式: 面交 保證期限及保證書:無 售後服務: 非人損個人保固1週 聯絡方式: 電話: 0960532293 信箱: thomas.lv(at)gmail.com
