Hi,
Calibrations of UCAC1 values near V4739 Sgr vs the Loneos data (at least those that positionally match...), show that UCAC1 values in the magnitude range 11.5 to 14.0 are about 0.3 magnitude lower than V for acceptable comparison stars, ie those with B-V<0.8.
A real pity that Arne's telescope will scratch some part of the structure when trying to measure this field...
Regards,
Berto
