Sky darkness: -- <Limiting magnitude>
Binoculars: Vixen Ultima 9x63 + tripod
|Star hopped eastwards from
nu and xi Dra to find this pair. One component (more southerly) is dramatically
brigther than the other (mags 5 and 7.4), with estimated PA about 30 degrees.
No colour was discernible.
The dimmer component (TYC 3916-698-1) drifted in an out of view - averted vision helped, but it was definitely there. Separation is 89" and thus not a problem to split.
According to SMP, 39 Draconis is itself double, but obviously beyond my binos' capability to split.

|With these binoculars, I
could find this star only by following a line of sight upwards from the
r/f refractor centred on the star and comparing the views. Using this method,
I confirmed that I was observing the correct star but couldn't detect any
companion using the binoculars. Perhaps a darker sky is needed or a sturdier
mount for the binocs is obligatory to split this star.
For the record: - the rich field 80 at X20 split the stars into a white primary with a very faint pale orange companion. A nice view of a wide double star.
