Was wondering if anybody does have a colour webcam collecting dust / not realizing there is one in the box unused.
You have a colour webcam in the form of crop movie 640X480 from your Canon 60D

sorry as the Mat Salleh would tell me "RTFM".

That is a 7X crop factor inbuilt. Coupled to the 4X barlow your effective magnification is 28X. Tambah lagi the 1.6X inherent in the 60D.
Effective focal length for in my case 500mm with an added 1.4x converter is 7800mm!
So jupiter or saturn will appear football size relatively speaking instead of current ping pong ball size

Now your video capture using the movie crop mode is in mov format.
you need to convert to avi mode acceptable to Registax 6.
I use the programme
eRightSoft SUPER Download and install. Take care NOT to install the BADWARE programme REAL PLAYER that tenggek with the software.
Should you terinstall REAL PLAYER google how to uninstall if the usual uninstall is not sufficient.
Using eRightSoft SUPER. set the following parameters.
Output COntainer: AVI
Output Video Codec: Raw UnCompressed
MEncoder
Video: Scale size: No Change, FPS:60 Bitrate:29040, Options: High
Quality, Stretch it
Audio:Disableor ask Shahgazer how to do the conversion using VirtualDub at a bit lesser quality .
cheers
