在太空人已登陸月面三十多年，Pau sir仍能憑一台以Royce主鏡自組裝成的254 f6牛反，在人煙稠密的香港島上環自家陽台，配個Toucam便可不下一次發現月面地貎，可說是業餘天文愛好者的典範，也真的能夠做到 "Put Hong Kong on the map" (Lunar map
)多謝Pau sir介紹，日後小組活動時又多一個具挑戰性的月面地貎了。

Enclosed image shows the Manilius and its nearby region. There is a small rille that was found by me at the end of 2003. It is unofficially named as Rima Pau and is listed in the Danny Caes' Unofficial Lunar Nomenclature http://the-moon.wikispaces.com/Unofficial+Names+(M+to+R)
It's another challenging feature for your Dob 16 to watch out or image. The location of the rille is near the north-east corner of crater Boscovich P, just south of crater Manilius. The rille runs diagonally from north-east to south-west. When I first found it, I thought it may be an artifact or just a streak of light. I sent this image to the Geological Lunar Research group to notify the other members. Very soon, its existence is confirmed and imaged by other amateurs too. They nicknamed it as Rima Pau. The rille is best seen when the morning terminator is not far away from Manilius. You may try to image it with your APM refractor or Dob 16. Good Luck to find something new on the moon!
