50mm f/3.5 refractor and ST-402ME camera


12P on the evening of 2024 April 20 UT was magnitude G=4.5 as calculated from 8x15 second images taken thru a green filter in an aperture diameter of 10'. The images were collected as twilight started to fade only to be replaced by Moonshine from the 87% illuminated Moon. It also did not help that all the images were collected below an altitude of 6 degrees. Most of the tail and coma were washed out by light pollution, twilight, Moonlight and atmospheric interference.
