tried V378 faster (Halifax)

Diminished returns. I asked the Burke-Gaffney Observatory to shoot M47 again but with a 1 second exposure. In hopes of split V378 A and B. They are about 5 arc-seconds apart. But B is magnitude 12. I don't see it.

Luminance only, 1 second subexposures, 20 stacked shots. FITS Liberator, Paint.NET. North is up; east is left.

First shot on 20 Dec '16.

Then again on 12 Nov '17.
