imaged FOX 134 (Halifax)

BGO imaged FOX 134, a neglected double-star in Perseus, a bit east of ν (nu) (off frame). This image is centred on Tycho 28710 1584 1. The target is the obvious tight double in the large triangular grouping of stars down and right of centre.

Luminance only, 2 seconds subexposures, 12 stacked shots. FITS Liberator, Paint.NET. North is up; east is left.

SkyTools 3 Professional did not include a reference to FOX 134. It does show a single star at that location: GSC 02871-1837.

I plated solved the image with astrometry.net. It returned:

Pixel scale: 3.59 arcsec/pixel
Orientation: Up is 0.00274 degrees E of N

I pulled the line item from the Washington Double Star catalogue:

03467+4241FOX 134      1923 2017   10 104 108   6.1   5.9 10.0  10.4            -040+004 +029-006               034645.01+423927.4

The 2017 entry shows:

position angle 108

separation 5.9

With magnitudes of 10.0 and 10.4.

Stella Doppie shows 3 sets of entries:

2007 5 108 5.8

2010 8 106 6.2

2017 9 108 5.9

With matching magnitudes.

Using Visio, I made a scaled ruler and measured the PA and Sep:

separation calculated 6.6 arcsec

position angle calculated 106.9 degrees

That's interesting. My numbers are similar to the SD data from 2010.

Curiously, Tycho 28710 1584 1 looks like a double!
