2022-04-03 NGC5055 M63 from Buford Mountain, MO

I imaged NGC5055 M63, the Sunflower Galaxy, on 03 April 2022 UTC 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.

32 Luminance frames x 5 min binned 1x1 and 8 RGB frames x 5 minutes each binned 2x2 for a total exposure of 4 hours 40 minutes. 16 flats, bias and darks frames.

This is an enlarged, cropped view of the galaxy that better shows the spiraling durst lanes.
