I used an homebuilt astrograph, like Newton , D = 130mm F / 2.8 (optics made by Massimo Riccardi). Sky very clear, temperature -3 °C, dry, without Moon. The comet was at maximum altitude above the horizon, and the minimum distance from Earth.They will note the dust tail well evident and pink, and then the ionized tail which forks and farther also shows detachments.
