When possible I like to monitor fainter objects. Here I have imaged Comet/2017 M5 TOTAS at 2x2 binning, a plate scale of 1.02" per pixel using an Rc filter.The comet's average  altitude was 38 deg.  Seeing was steady, but  with some high  thin high cloud.

Using Astrometrica  10 x 90 sec images were stacked by addition  on the comet's motion.  Mag R was determined to be 18.25 +/- 0.04.  Measuring aperture radius 6".
