Making of 16 inch PTC telescope - 9, Telescope Finished
Dear ATMers,
The telescope was completed. Under very limited budget and tight schedule the telescope was still finished well before expected.
The whole telescope was made by wood – the “All Wood Telescope “. As I have mentioned earlier – wood is cheap and friendly to work with and this showed a real proof of my saying – the OTA was finished just in two days, with only a handful of primitive equipment – a jig saw and a router. No milling machine, no lathe and no specialized machines required.
After two nights of trial and testing the whole telescope showed a stable structure and smooth turning. One word – it is a pleasure to use this scope, despite of its ugly outlook.
There is only one thing left to be done – coating of the primary mirror.
Best regards

Dear Mr. SiuSiu,
I am sorry. Just asked WongSir - on 19 July Astrofarm is not available. I think the first light must be arranged in some other days or some other place.
Best regards

不如十八或十九號呀? 而且,話明是 北潭涌簽名版,在北潭涌開光會否
更好?
不過,如果是因為踱膜的關系,那就無所謂吧!
You are absolutely correct !
I am afraid that the mirror will return not until 18th. The plane on 20th is a morning plane and thus the only available first light will be on 19th.
How about 19th first half on PTC then ? Will not stay overnight since we have a plane to catch next morning.
Best regards
