returned to STF 2146 (Halifax)

Returned to Struve 2146 aka HD 156162 or SAO 30299. Still trying to wade through my confusing notes.

It's a triple. AB are very tight. In Draco.

Struve 2146 in luminance

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.

Is there a partner to C?!
