imaged NGC 2359 (Halifax)

BGO imaged NGC 2359 or Thor's Helmet for me again. I had first tried on 7 Dec '16. I cranked the stretch in FITS.

Thor's Helmet in luminance

Luminance only, 60 seconds subexposures, 10 stacked shots. FITS Liberator, Paint.NET. North is up; east is left.

Took Oxygen-III data this time.

NGC 2359 in O-III

Wow!
