Latest images I have taken of Comet Catalina in the early hours of 19th Jan show no ion tail. Should have been clearer than in first images taken on the 15th as much higher in sky and after street lights turned off. Much more moonlight though. Dust tail better in more recent images. I have been thinking that moonlight might affect visibility of ion tail more than the dust. Otherwise, I suppose it could be a line of sight geometry issue? Any useful comments would be welcome.
