Merlin66,

Attached is a screenshot of the field in UCAC3 (left) and UCAC4 (right).
It's easy to pick out stars that UCAC3 missed and match them to the
previous photograph of the field (the brightest star at 10 o'clock from the
cursor, for example).

Thanks for recommending the upgrade to UCAC4.

Cometcatcher, you can do a similar comparison with a photograph to test
the accuracy of star brightnesses in Stellarium (or any other planetarium
program).

Clear skies,
