Steve's Notes
=====
NGC 147
17.5" (10/13/90): fairly faint, very large, elongated almost 2:1 SSW-NNE, 5'x3', very low almost even surface brightness. A mag 13.8 foreground star is superimposed just north of center. The halo gradually fades into background.
17.5" (8/29/92): appears larger (8'x4') using 20mm Nagler in the White Mountains (elevation 12,500 ft).
8" (8/28/81): very faint, moderately large, slightly elongated, diffuse.
24" (1/1/16): Hodge III is the brightest globular cluster in NGC 147 at V Å 16.5. At 450x and 500x it only occasionally popped but was verified at the same position using a detailed finder chart.
I first identified two mag 13 stars at 1' separation oriented N-S, which are situated 5' SSE of the center of NGC 147. These stars are just outside the halo of the galaxy. A mag 14.7 star is 1' further NW, forming an obtuse isosceles triangle with the two mag 13 stars. Hodge 3 is 41" N of the mag 14.7 star and nearly forms the 4th vertex of a parallelogram with these three stars.
