spotted HD 36073 B (Halifax)

BGO robot imaged HD 36073 aka β891. This is a multi-star system in Taurus at the outer edge of Collinder 65. When I first tried to observe in 30 Mar '13 I did not meet with much success. In this image, I can see the B star of the quad. w00t!

multi-star system HD 36073 in luminance

Luminance only, 4 seconds subexposures, 20 stacked shots. FITS Liberator, Paint.NET. North is up; east is left.

The B star is very faint compared to HD 36073 A. It is to the east-south-east of A. Delicate. C is the bright star to the north. But I cannot split C and D in the image. Then again, they are very tight, at less than 2 arc-seconds. I've still not spotted D so I'll leave it on my View Again list...

HD 35985 is to the south-west of Burnham 891, equally bright. I split the tight pair back in 2013 but they just look like a rod or elongated blob here.

South of BU 891 is HJ 3274, a tantalising faint equal pair. Also previously split.
