Thanks Rick, I have just checked it with Ron Wodaski's CCDCalc - and I get 4.2 arcsec/pixel with the reducer. I was pretty sure that I entered in 255mm for the focal length - buuut - it was late so anything is possible. Although surely the focal length it calculates from the image after solving should be correct??

hmm.....what? Can you repeat that more slowly for the intellectually challenged among us (ie: me!)
