Telescopic comet Mrkos, Orimattila, Artjärvi, Tähtikallio

124P / (Mrkos) The periodic comet of the Jupiter family was filmed on the second night of the March work. The asteroid-like comet is now closest to the earth and thus well described. The comet was discovered by Czech astronomer Antonin Mrkos at the Klet Observatory on March 16, 1991. Antonin Mrkos has found a total of 13 comets and 274 asteroids, source Wikipedia https://en.wikipedia.org/wiki/Antonín_Mrkos . In his youth, Antonin was an avid amateur astronomer who also made his own telescopes. The largest lens was as much as 65cm, source BLANSKÝ FOREST & NETOLICKO http://www.blanet.cz/cz/doc-rndr-antonin-mrkos-csc-/144/ . Antonin Mrkos became the director of the Klet Observatory in České Budějovice in 1965, the telescope was a 0.57m / F5.2 telescope with which observations were made until 2002, when the KLENOT telescope was added, source Wikipedia https://en.wikipedia.org/ wiki / Kleť_Observatory . The comet already had a highly concentrated coma (star-shaped) when it was discovered, source GARY W. KRONK'S COMETOGRAPHY http://cometography.com/pcomets/124p.html . When photographing the comet was 0.785au away, the closest it was 2 days later 0.765 au on March 16, 2019. 1Picture. Average stack by comet. No coma or tail was observed.
