Kermit,

as asked, data is as follows :

PA Zet Cap       64.55 degrees

Altitudes, including Dip & Refraction

 Peacock    16d 49'

Alnair           33d 57'

The Zet Cap altutude of 28d 22' previously given is corrected altitude ( clear of dip & refn )

NOTE :   these results are only given to nearest 1' of angle because of several factors.

1.     the picture scale gives a resolution of a little over 2' af angle per pixel in the centre

2.     the lens distortion I estimate to reach about 6 pixels in the extremities, but the pattern is not known

3.     the Dip used is 3'.   See the Suwarrow beach picture shows the island is maybe 5 ft above high water

        and the star picture was likely taken on a tripod or table for steadiness for long exposure, so perhaps 10 ft above S/L

It is good luck that Peacock is at the centre if the star picture. If it was not, the PA's calculated would have unknown

errors.

Over to you then.
