Hi Ian,

It certainly is difficult with a hand mirror because if you stick it in there too far it blocks the reflected image from the primary mirror anyway. You can get it using just the very corner of a small rectangular mirror, but a dental style mirror (as sold by some car accessory shops) is better I have found.

Cheers
