Guide camera..old DSLR?

Wondering could I use an old cannon 300d as a guide camera. Although old it would seem to have a big enough chip...anyways can someone tell me why it won't work...the scope 80 x 400 refractor doublet...

Hi Alex,

I'm not sure if you meant using it as a guide camera to feed a signal to an auto-guided mount, but if you did, then no. The camera does not generate the right sort of control / correction signal for the mount (EQ5 or 6, etc..) to use.

Also although the 300D has a composite video output, it was before Canon employed live view (on/after 450D??) , so I doubt you will be able to see LIVE what the camera sensor is seeing, BUT plug a monitor in to the video output and see what is shows. If the 300D did show the image live (doubtful) you could use it to hand guide the mount with a suitable lens.

Best
JA

Hi JA
I don't think there is much hope for the idea but thank you for considering my question.

It seems the load star camera is on the top of the list at the moment.
