It's a triple. AB are very tight. In Draco.
Luminance, 0.2 seconds, 20 subs. FITS Liberator, GIMP.
C is the obvious bright star to the south-west.
I don't think I can split A and B in this image. According to SkyTools 4, the PA is 225° with a separation of 2.70" (as of 1998). That angle is roughly the same as C.
The star west of A and north of C is J171259.2+540815 at magnitude 16.46.
First imaged this target on 25 Sep '18. Imaged again on 20 Sep '21, at a 1/10th of a second, oh, and with the SBIG sensor.
Is there a partner to C?!

WDS entry updated! There's no B. The tight companion is near C. See the 29 Aug '21 blog entry for details of the change.
