Ahh, forgive my ignorance! How does that size compare to when you look
through in real life? I've got a 76mm reflector and mars to my eye is
tiny.


The webcam image is much larger than you will see through a 26mm eyepiece.
I don't know the exact figures but try using the following simulator

I use 8"SCT f/10 and Meade DSI (similar size ccd to toucam)
I hope this helps.

Cheers
