I seem to remember this came up a while back. My solution (theory only never tried), which came up as an offshoot of some work I was doing on the effects of tilt errors on a mirror AH, was that if, you could set the mirror accurately to any angle, you could get rid of 20 degrees of height sextant required for every 10 degrees of mirror tilt. It did rather look as if you might possibly have to place your body in a rather unusual position in order to do the shot. Appologies if I,ve use this photo before. Dave P
