It looks similar to those sold in Ap Kee, but I am not sure because my telescope is second (or third) hand. BTW, I saw your Jupiter photo, how did you center the target and focus?

No big deal as photos. Both pictures were taken on 06 Mar at the rooftop of my home. As expected, Central is the brightset part of Hong Kong and no star can be seen. However, it is interesting to see the difference between the IR and visible sky.

The camera is actually a small DC (see dpreview.com for specs). I used an universal T ring from Ap Kee. The ring can be clamped on the focuser tube.

其實我想問: 咩野係infrared photo 呀??
The Photo captures infrared light coming form the Moon ranging from 0.7 microns to 1.1 microns, but I think the cutoff is not very sharp.
