shifted to NGC 1975 (Halifax)

As expected the skies cleared over Halifax. I had 4 items in the queue.

The BGO robot imaged NGC 1975 for me. aka Ced 55c. Previously, I had aimed directly at 1973 and 1977, all in the area of the Running Man Nebula, north of the Great Orion Nebula. 1975 is above (north) 1977; 1973 is below and to the right (south-west). It seems that 1975 is the faintest of the reflection nebulae, centred on the multi-star system STF 746.

This whole area is considered one of the RASC Finest NGCs. The RASC Observer's Handbook has the entry notation NGC 1973+ meaning 3, 5, and 7.

Luminance only, 30 seconds subexposures, 10 stacked shots. FITS Liberator, Paint.NET. North is up; east is left.

There are problems in the bottom-left corner of the frame.
