I have been imaging 9P/Temple 1 which is brightening but the other night it was very close to a bright star so I elected to image it’s nearest neighbor comet, 62P/Tsuchinshan 1.
62P has a relative motion of 0.5 arc seconds per minute. With my sampling density of 2.5 arc seconds per pixel with the E160 and SXV-H9, I was able to take 6 minute guided (on a star) subframes without undue comet blur. 62P is about magnitude 13, a magnitude or so dimmer than 9P, but it is also about 15 degrees higher, so less atmospheric extinction – and skyglow, which I have lots of!
