returned to 16 Eri (Halifax)

Centred on star GSC 05878 00248, I tried to image 16 Eri, aka tau 4 Eri and JC 1, again. Previously imaged this object on 7 Jan '1820 Jan '18, and on 25 Sep '18. Wanted to have another go.

multiple star 16 Eri in luminance

Luminance only, 0.1 seconds subexposures, 12 stacked shots. FITS Liberator, Paint.NET. North is up; east is left.

I continue to try to coax out the B star in this system. According to SkyTools, it should be to the west. On a line between D and E. Um...

The primary sure doesn't look round but there are registration issues.

I think it's time to let this one go, at least in terms of imaging. A is too bright and B is too close.
