tried to find BRT 343 (Halifax)

Chose 17214+4552 BRT 343 from the WDS which appears to be a neglected double star. It was viewed once in 1894 and never again since. That's 125 years. Ordered BGO to aim at TYC 3508-0354 1 in Hercules.

possible location of BRT 343 in luminance

Luminance only, 1 second subexposures, 12 stacked shots. FITS Liberator, Paint.NET. North is up; east is left.

From the database:

WDS id: 17214+4552BRT 343
discovery year: 1894
position angle: 213
separation: 4.5
magnitudes: 11.48 and 11.7
precise coords: 172125.19+455221.5

Hmmm. Tycho 03508-0506 1 in SkyTools is at shown at this location. This is the somewhat bright star up and left of centre, north-north-east of Tycho 0354 1. ST3P says 0506 1 is magnitude 11.4.

I'm looking for a star of similar magnitude near to or touching. Assuming the PA is correct, it would be to the south-south-west. Nothing super-close at that position.

Know what's at the position angle of 213° that's magnitude 11.7? That Tycho star! That separation is handsome though: 1' 57" or 117". Not 4.5".

Neat star patterns in the field. The string to the south-east and the oval to the top-right.
