Found the double with the 19mm Panoptic and then split the double at 90X with the 6mm Radian. You could note the 2 mag difference with the secondary much dimmer because of the almost full moon. Both white.

Had a hassle with this little pair . . . it was high up by now, and I kept losing it! Primary pale orange, no color noted in little secondary.
