Currently, I mainly use a 10″ f/6 Newtonian reflector for my visual observation and imaging of the Moon and Planets. For high resolution imaging, I use a 5x barlow and a Philips Toucam Pro webcam. The advantage of using webcam is that it can catch the best seeing moment during the image capture process. Then the AVI file is processed and stacked with Registax and the resulting image is further processed with Photoshop. However, my CN212 is also a fine telescope for visual observation and imaging too. I used it to take many fine lunar images before I acquire the 10″ reflector. I am a workshop instructor in a local vocational institute.

My observing site is located just on the outskirts of the city center of Hong Kong. It’s surrounded by skyscrapers. During the night, flood lights from commercial buildings illuminate the sky like the day. Under this sky condition, I limit myself to observe bright heavenly objects such as the Moon and the Planets. However, the hot air currents dissipated from neighbourhood air-conditioners affect the seeing condition very much. The seeing condition at my site is always around 4~5/10 and seldom reaches 7/10 or higher. The only way I can do is to wait for the short but best moment to press down the CAPTURE button.
The waiting time may be an hour or more. I am lucky that my apartment has 2 balconies facing at E-S and W-S direction respectively. Usually, I observe at the W-S location because I can easily get access to my computer and other facilities.
Anyway, I have to wait for the objects to come out from the neighbouring skycrapers.
