香港天文論壇

Wongsir, Thank you for the link which I can see content of the《天文望遠鏡製作》講義。The wording display is normal after setting to Big 5 from Unicode (default setting) in Chrome referring to your guideline. However, I noted that some pictures are still no display, see image in attached file. With best regards...

Wongsir, please teach me how to obtain electronic format (e.g. PDF) for the 《天文望遠鏡製作》講義 caused I can't find it.

Thanks with best regards,
Peter Chu
