123P/West-Hartley is a 12th magnitude Comet appearing in the constellation Ursa Major. It orbits the sun every 7.6 years at an average distance of 3.9 AU.
The comet last passed perihelion on 2003 December 9. Magnitude estimates generally exceeded 15 as 2004 began and peaked at between magnitude 14 and 14.5 during February. Close approaches to planets: This comet made 2 close approaches to Jupiter during the 20th century. It makes no close approaches to within 1 AU of any planet during the 21st century. (From the orbital work of Kazuo Kinoshita)

They are rare objects but it is worth trying. They can be photographed with short exposures with traditional VA chips such as the IMX224 or the IMX294. Better to use a small FOV to see them better. The Skysafary shows them on live screen
Thanks Chris and Ken for you comments
