Fig.24a - Comet C/2018 Y1 Iwamoto and the galaxy NGC 2903 in the constellation Leo on February 13, 2019. Image taken through a 16-inch f/4.5-Dobsonian
("Ninja") on a dual-axis equatorial platform created by Tom Osypowski. A Canon EOS 450Da camera and a TeleVue Paracorr coma corrector (multiplying the
focal length by 1.15) were used. Stack of forty-three 1-minute exposures at ISO 800 (total exposure time 43 minutes). Strong moonlight partly ruined
the colors of the image.
