今明两晚，继续为4月份现货销售S30 Pro前，预订了朋友提供免费工作坊。早上还是大雾迷漫，可幸一如天气预测晚上云云散去一大部份，工作坊得以顺利进行，完成室内讲解后，到户外示范了地平及赤道模式，拍了月亮及M3球状星团，又让大家实习，并到天文台用Celestron EdgeHD14看月面。很高兴今晚有十多位朋友週五晚专程来星河科研社大美督基地参与，明天再有另一场，6月还有两次机会，所有预订朋友务必把握3个月有效期参与。 Tonight we held another free S30 Pro workshop for customers who had pre-ordered before the April in-stock launch. Morning fog was heavy, but the sky cleared as forecast, so the session went smoothly. After the indoor briefing, we demonstrated alt-az and equatorial modes, imaged the Moon and M3, let everyone practice, and viewed the lunar surface through the Celestron EdgeHD 14. Glad to welcome over a dozen friends to our Tai Mei Tuk base tonight. Another session is tomorrow, with two more in June — all booked participants should make use of the 3-month validity period.
