Details:
As the window for observing Comet Lemmon comes to a close, it will be remembered as the very long period visitor that put on a good show.
Although the comet is at its peak brightness, it is considerable smaller since its closest approach 10 days early. However, its long blue ion tail seems to be the longest during its journal around the sun.
This image combines 25x20s subs using a Fujifilm X-T5 (raw), Nikkor 180mm f/2.8 @ f/5.6, iso 800 under 64% moonlit skies with a Bortle sky brightness of 5. Fixed on stars with comet showing minimal drift.
The 2nd image: Using PixInsight, I took 75x20s sub fixed on Comet Lemmon and muted the stars. This image shows the fine structures within the narrow ion tail (left) and broad dust tail (right). Tail length in this cropped view is ~5 degrees long.
