Comet 45P, at last there were some subframes usables, with individual background extraction, so that I could integrate some of them. Now the split tail is well visible.
Parallel exposure on ASA DDM 85 mount:
(1) 7 x 60 sec Hyperstar C14/F1.9, Lumicon comet filter, ASI 1600 mono, cooled (-32° C), processed as emerald green in the RGB image.
(2) 7 x 60 sec RASA 11"/F2.2, L-filter, ATIK 490 color, cooled (-18° C)
FOV 1° x 0,9°, location: Tenerife 1180 m altitude. 19:20 h - 19:50 h UT (with many missing subframes due to clouds)
