NGC 2371 aka NGC 2372 or NGC 2371-2 or whatever

Yet another weird entry in the NGC, NGC 2371-2, is a lovely bi-polar planetary nebula that got two names because it visually looks sort of like two separate objects.

NGC 2371-2; 20 x 120 luminance, RGB 10 x 120 binned 2x2.

NGC 2371-2; 20 x 120 luminance, RGB 10 x 120 binned 2×2.

Images make it clear that both objects are part of the same expanding shell of a fine planetary.  This was a really crisp clear night, in the 20’s.  I had real problems with the corrector plate  dewing up and freezing, especially on the RGB frames which were done last.  The image above is cropped.  I measured it in Photoshop to be  about 2.3 x1 arc-minutes.
