2022-10-23: NGC0246 the Skull Nebula

I imaged NGC0246, the Skull Nebula, with NGC0255 over four nights from September 27 to October 18, 2022 at the Buford Mountain Conservation Area. They were imaged through a 200 mm aperture, 730 mm focal length F/3.65 Boren-Simon PowerNewton Astrograph with 0.73x focal reducer and coma corrector. The imaging camera was a QSI683wsg-8 with Astrodon II filters and cooled to -15C, with off-axis guiding. The system was mounted on a Losmandy G11G2 equatorial head on a permanent pier. The system was controlled with Sequence Generator Pro and PHD2 and the image was processed in PixInsight.
