Dear ivanhsiu,ivanhsiu 寫:首先要多謝黃Sir、蔡Sir及各位師兄、師姐的教導、指點，獲益良多，再次衷心感謝。辛苦你們。
已試鏡，望月影像清晰，好滿意及開心。
我的子女開始為鏡設計圖案及選色，有排玩！
遲些配鏡mount、脚架等。請問有沒有好介紹？

Good to know that your children love your homemade telescope.
I will arrange a meeting later, may be early October, since at that time the temperature is more suitable to have a gathering in our farm.
Usually, I will give an advance course on telescope making.
In the meeting, tele accessories, such as finder, barlow, tube mount, tube balancing, equatorial mounts, different kinds of telescopes... will be introduced.
Hope we will meet again later.
