Image of comet C/2018 Y1 (Iwamoto), passing the open clusters M38 and NGC 1907 in Auriga. Obtained on 2019 Feb. 28 (21h40-22h47UT)
with 15-cm, f/6 Maksutov-Cassegrain astrograph and Canon EOS 6D DSLR. Exposure time was 22x180 seconds at ISO 3200.
Total exposure time 66 minutes. FOV is 2.29o x 1.52o. Image scale is 6.0 arc sec/pixel. There is a ghost reflection
between the comet and clusters due to optics design and relative proximity of bright star Capella. The comet left a fuzzy trail because
telescope guiding was on stars. Copyright © 2019 by H. Mikuz, Crni Vrh Observatory.
