5a 16th Century Danish Astronomer Just back from a week-end break and find that the answer to this appears to be the First name of BRAHE i.e. TYCHO Brahe, in order to fit with 6d Y-AXIS. Unless of course there is an R-AXIIS but if not then the setter is somewhat amiss by misleading us in using the first name of BRAHE in order to fit in with 6d.
Hello supersuezy, You obviuosly did this clue before the 6d and "Hit Lucky" because it is the first time I can recall that a setter has asked for the first name without printing the surname i.e. __________BRAHE
