Star collimation/APT

[Guest]

APT has a collimation aid. According to the general descriptions about star collimation you have to use a high magnification. I was wondering if I'm using APT and I use the x10 zoom feature is that the same as using a high magnification through an eyepiece?  I'm not quite sure how you'd calculate the equivalent magnification with a 1000mm focal length telescope and a canon 450d at prime focus. If that was equivalent to say x20 and I use the x10 zoom then I suppose that would give me an overall magnification of 200 which is what's suggested for this kind of collimation but is that the same as having x200 through an eyepiece?

Cheers

Lots of opinions on collimation, I would start with eyepieces, working up to say 300X, but final check with the camera with magnified LiveView, which hopefully won't need any adjustment.
