為紀念廖生對香港天文界貢獻,我認為太空館負責人日後應該考慮向政府建議張何鴻燊天象廳改為廖慶齊天象廳。

The memorable Joseph Liu's group photo at the AstroPark opening ceremony on 30-01-2010, when Liu was invited by Space Museum as their advisor to come back.

He was always a good astro teacher. When I sought his advice, he was still very keen and kind to advise me in details how to make a motorized roll-off observatory.

My email with him :-

Dear Raymond,

Thank you for your message and the attached photos, and also your nice Web Site. You surely are lucky to own a private observatory in Hong Kong, and your main telescope mount is beautifully and strongly designed. I also own a Takahashi EM200 mount, but it was produced about 20 years ago and thus does not have the goto convenience which is so handy and important to an old man like me. The both EM10 and EM200 that I have are still doing excellent service. As a matter of fact, Takahashi products are usually very reliable.

The motor which I employ to move my observatory roof was manufactured by DAYTON that I purchased it together with the two winches from local hardware stores in 1990 or 1991. The motor is of 1/8 H.P. , and works very well for my heavy roof which measures 12' x 22' and is made of ridiculously heavy wood materials ( required to conform with the silly local city building codes ! ). The nylon rope that I mentioned to you earlier has served me since the building was completed in March 1991, without the need of a new and clean-looking substitute, and it is, to me , much safer to work with instead of steel wire that when snaps, it would kill or seriously hurt anyone working nearby. I use only one motor which is reversible in order to safe space and money. In fact the motor was not expensive. It seems that I paid less than US$200 for it. You would need to make a metal coupler( a simple brass or iron short tubing) to connect the motor and the winch(es) to allow the winch(es) to turn. The motor hand control switch box(es) was designed and made by our mutual friend --- HKAS former chairman Mr. LEUNG Kam Cheung when he came to visit me and stayed in my house for about a week in 1992(?), with the help of my younger brother. I must say, however, that my whole roof running system must look very primitive and old fashioned, and you may not like it. So, the materials (attached images) are just for your reference. Don't forget that I am an aged and old-fashioned fellow.

Along with the motor system illustrations, you may notice I have also included a few pictures of my observing equipment and a couple of astro images for your interest. Hope you would like them. The M33 picture comes from a stack of three 10-minute exposures taken with a Canon EOS 10-D through a Takahashi Epsilon -160, F3.3 in 2004. It appears to me to be a rather "noisy"one, yet still quite acceptable from a 16cm instrument which I bought from Japan about 30 years ago.

Thank you once again for your kind message, and I wish you clear skies and good observing and imaging.

Regards,

Joseph

Dear Mr. Joseph Liu, Here is a group photo taken with HKAS members for your attention. Further, I am quite interested in the motor (with pulling distance for 25 feet) you mentioned, as I am now planning to install a motor to pull open/close my roll-off canopy (moving distance about 10 feet), as shown in the attached photo. Do you have the particulars of the brandname/model no. ? Or a website link ? My next step is to remote control the roof top observatory which is located in Sai Kung, about an hour drive from my home.

And when I had a chance to go on a working trip to San Francisco in 2010, naturally I visited his home observatory, and
enjoyed an afternoon tea/biscuits in his house.

雖然從未有機會和廖前輩會面,但對他的離世也深感遺憾。相信他對其徒子、徒孫今日的成就也一定會欣慰。

You can go to the Space Museum to sign on the Memorial Book. There will also be an exhibition on Mr. Liu.

老人家的記憶若沒錯的話,有一本雜誌叫"科技世界"曾介紹過廖生上水天文臺。後其,這本雜誌改了名,好像叫 什麼呢?
