It's difficult to find this
double. Therefore, it will be essential to have a good skymap. The field
here is faint and rich.
Using 163x magnification I observed the companion without difficulty. The colours noted were pale cream for the primary and orange for the secondary. It was a pretty faint close pair. Using MicroGuide at 263x I obtained some measurements which from an average of 7 measures gave a PA of 147º3 with a separation of 2"1. Rating: 3
