Corwin's Notes

=====

NGC 1731 is an association in the LMC centered about two arcminutes west of 
JH's position (very good) for the double star towards the eastern side.  DSS2R 
(from which I've estimated the position) provides a very good view of the 
object; it is about 5' x 4.5' across with some very faint nebulosity involved.

Steve's Notes

=====

NGC 1731

18" (7/9/02 - Magellan Observatory, Australia): at 128x this is a large region of nebulosity (LHa 120-N4) and scattered stars (association LH 4), 6'-7' diameter, involving the double star h3710 = 10.7/12.7 at 12" and a number of fainter stars.
