Position: RA 12:21 DEC -11:29
Description:
A wide pair easily split at low power. In the same FOV there is a third star somewhat removed, which gives this overall an appearence similiar to STF 1619: a long, narrow acute tirangle. Of the target pair themselves, the primary is blue, but it is hard to tell about the fainter companion - perhaps it might have a tinge of yellow. I measured the separation at 14.9, and the PA at 174.6 (ave of 5 meas).
